Is Digital actually better than Analog?

Dear T bone: Very good point. I totally agree with you.

Regards and enjoy the music.
Raul.

Shadorne, I note your point on anechoic chambers. I have beeen in one once and it was wonderful, but the person I was with couldn't handle it for more than two minutes. My point was not that they are comfortable environments without appropriate references, simply that... in order for a M-Ch system which produces spatial cues to be perfectly accurate, room interactions still need to be dealt with. One way is extreme nearfield listening in a room with no delayed reflections. This goes with your point that room effects are a huge factor.

The thing which noone has mentioned, but which I find to be a crucial part of live music, and a fundamental difference between live music and music at home, is the listener's visual interaction with the performer and vice versa. Is the performer interacting with the audience, the stage space (wandering around a big stage or only inhabiting a small space, controlling it or not, comfortable or not, familiar or not), his/her own performance (smiling at his/her mistakes or frowning, improvising slightly or faithful to the music that everyone knows)?; do the band members grin like little kids when they really nail something well together? Do they joke with each other and the audience? Does the solo cellist hold on to a vibrato in a certain way precisely because he can, precisely because he knows it will thrill the particular audience he is playing for tonight? All of these are, for me, a sine qua non of live performance. Hell, not all live venues have as good sound as my living room, but I daresay watching Hiromi Uehara jump up and down on her piano stool as she's playing, or watching a great cellist subtly change the decay of the coda of a sonata from piano to pianissimo because the venue is small enough and well-enough-designed to handle it, or watching Bill Frisell play with reverb tools while in mid-song just because it'll have an effect he hasn't tried before - all these are the things which make for the most interesting live music. To those who have said that live music is their reference... I'd ask them to think about that. It's a wonderful ideal but I know of no stereo system which will improvise because the audience would welcome it, or where one will be visually surprised because the pianist stuck out her tongue to reach the high notes.

...the rise time and, more importantly, the decay time is appropriate to reproduce the sound of a real instrument

As you say, the decay is extremely important. This is related to how well the electronics perform reproducing the medium and, in particular, to the "audible dynamic range": the sound of decay may be there -- but imperceptible due to noise, etc.
Strangely, some systems sound pleasantly "fast" and crispy (both) when there is minimum sound of decay that is reproduced. OTOH systems I've heard with considerable rendition of decay are much more involving -- and "dynamic" in the audiophile sense: the "sudden clash" is VERY sudden.

D_edwards sez

...I claim that surround is better for digital

Actually, I like the effect of well executed surround sound. Also with an image attached to it:)!
I have a 2-channel system, myself. I like the sound -- and I'd better like it: I can't afford multichannel, and the paucity available music is irksome -- although one can create a livable "surround" artefact even with two channel stuff...
But as I said, I can in no way afford such a venture.

I think that as long as we all enjoy some music, there is little reason to pontificate one way or another. I even have friends who listen in mono!

“as we have already discussed my two-channel system is at least equal to your system.”

Sure Eddie. Pray tell the good folks on the board just what system do I have that your two channel can match? Of course you know what system I have, as you wouldn’t blatantly make such a statement without knowing the facts would you? I mean, you only make statement like these when you know the facts, right?

Sorry Eddie, from what you describe you have little to no idea of what analogue is capable of, but at least I now understand the source of your confusion.

To kind of add to this thread, moving on from the Analog or digital, surround or stereo divides, I suggest that it is hard to create reality from a few squiggles (Analog or digital, mono, stereo or 7.1). There are a couple of areas that can be improved though...

IMHO, the most obvious difference between live sound and playback is dynamics. Music loses impact without dynamics and detail is less audible too. A very good system in a good room can usually produce timbre so well that it hard to tell the difference tonality (at least not without a direct A/B comparison; instrument versus speaker). Unfortunately most recordings (even some of the best) are compressed ...so even on a good system they often won't sound anything near life-like.

There may be good reasons for mild compression; it is more comfortable to listen to and it limits distortion/speaker damage from nasty high SPL transients. Some soft sounding instruments and some vocals may fair quite ok with compression, but most music/instruments are played to be heard at a distance, such as the piano forte, and in real life these instruments have huge dynamics and one can easily sense the lack of convincing dynamics on a stereo playback.

A good system test for dynamics is Yim-Hok Man "Poems of Thunder" CD (Naxos).....plenty of transients and dynamic range on this one. This recording is one of the more convincing life-like ones; Yim-Hok appears to be playing live, in front of you. The drumming is alternately soft and then loud and the transients will make your heart jump. Totally exhilarating, somewhat deafening and a litle tiring to listen too for anything but brief periods ....just as it would be with Yim Hok and a real drum set brought into your living room, six feet in front of you. This drum recoding comes across without the slightest hint of boominess...nearly all transients.

The second big difference, IMHO, between live sound and playback is the room itself....more often than not our ears are well aware of the room size from the reverberant sound field and this tells us that the orchestra playing from the stereo does not fit or else there is some reverberant sound in the mix that cues us that the real venue was indeed much larger than our living room or, in most cases, we get some combination of the two reverberant fields (confusing/conflicting information).This may explain why we close our eyes when we want to listen critically and why a great mix can make us feel that we are there in a larger room. Surround sound, I suspect, can help to counteract this reverberation problem, but it won't completely eliminate the room. Anyone who is skeptical of our ability to detect spatial clues, needs only walk through a church door to immediately recognize that our hearing is capable of sensing the dimensions and space from the reverberant field. Blind people use this everyday to get around; they sense their surroundings by using a stick tapped on the pavement as well as the reverberation of natural sounds. This phenomenon also allows us to sense when someone has quietly crept up from behind because they alter the reverberant sound from behind us.

BTW: An anechoic chamber makes most people feel nauseous, due to the complete lack of spatial clues to match what is seen with the eyes...the brain struggles to reconcile the conflicting information.

Greg excellent bravo,

"I don't think there is a "live" system to be bought:);"

A little advice....DUCK! and cover , if that advice came too late...stop drop and roll

Of course you are dangerously close to my side and I will tell you that it can be no fun over here if the skin is thin.

"a music lover can be happy listening to music on a little radio"
agreed
I'm not sure everyone else understands that and yes Guido's point were very insightful.

As you know Greg (or maybe you don't) I have drawn the Ire of the cogniscenti here because I claim that surround is better for digital.

What I am trying to establish is why is this so offensive a concept that people would be motivated to belittle me to the degree above and yet seem to ignore that atleast by your standards I should have a grasp on two channel pretty well and live sound. What is it exactly about surround that makes audiophiles cringe, for me it has given me the freedom to dial in my system to perfection for all types of music. My solution is well tested and my surround system outperforms my two channel system...without spending more money to play old records, I don't see a way to make it better and I've got $9K wrapped up in analog, have I spent enough? :)

I appreciate the extensive thorough input and I agree with and or accept all of what you said, to me your effort is noble and I appreciate it.

Gregm, Just a thought in addition to your comments on 'dynamic range'. I've come to believe that the real importance of getting a system to sound like 'live' instruments, is not so much the difference between minimum SPL and maximum SPL, but whether or not the rise time and, more importantly, the decay time is appropriate to reproduce the sound of a real instrument. (This would apply to the recording process as well as the playback process, can't get blood out of a stone). Just a thought.

Holy smokes. You guys are like pitbulls at opposite ends of a rope.

Dear D
I don't think there is a "live" system to be bought:); and a music lover can be happy listening to music on a little radio... Guidocorona aptly notes in a recent posting that reproduction is "hyper"-realistic rather than "real". I would subscribe to this way of putting things!
As a reference, however, live music does allow us to know what certain instruments sound like -- a violin, for example, or tympani being struck, etc

Equip:
AS you are an audio professional, you obviously know that your equip is first rate... shortcomings, if any, are probably the result of external, rather than internal, factors.
One of these factors is the record/recording -- but we have to live with that.

Further ideas related to points you raise in yr post:

Dynamics limitations: I believe that it's necessary for a system to have dynamic capabilities exceeding the medium's rated limits.
Now, the sound comes from yr spkrs. Your spkrs should allow ~1-100dB spl swings without major audible problems in a critical range b/ween 80-12kHz. Anything that constrains that would be either upstream, or extraneous.

One of these "externals" is noise that we get through the mains and is fed into the system and of course exits through the spkrs.
Measure the system inherent noise (i.e. no music) coming fm yr spkrs at a reasonable position at reasonable volume (you may be picking up EMI). This will include ambient noise you can do nothing about, so try this at a quiet moment.

For example, I had ~35-40db (!!). Given the same, say, 100dB capability, my sound would only reach 60 -- and that, at high spl in order to go beyond the noise level. High spl means my spkrs would be close to, or reach compression. Even before that happens, my wife & neighbours will have charged in the room.

If this measurement is significant in yr case too, try out an inexpensive 20amp filter/surge protector (tripplite, for example, makes some). I had one made by a friend. Leave the magical audiophile filters aside for now. Measure the noise floor again: it could be lower by ~20dB. Basically, you have gained AUDIBILITY of ~20dB "headroom" that yr system has anyway but was buried under the noise. This is randomly called "loss of fine detail" etc, in audio-speak.

An additional trick is to use very sensitive spkrs -- horns for example. While this is a personal choice and yr ATCs are excellent IMO, I mention it as a way of introducing artefact to *simulate* the dynamics of a live event... somewhat. It can work in a small room but for a limited FR (mid & bass requires room and horns are huge).

Further helpful is a source signal amplifier with very high dynamic range -- in yr case, the phono equaliser for example.
Further upstream is the phono cartridge; excepting latecomers, these have not always been very good at dynamic levels. Fortunately for them, many recordings have been equally limited, so the problem was less acute. Please note, however, that just as many recordings of the 50's & '60s already had a quite wide dynamic range!

{Note: I'm not concerned here with linearity of the equalisation curve, etc -- just dynamic contrast in the sound and perceptible in a medium-sized (~350) room.}

The ability of each source component to correctly "drive" the load is important for minimal energy loss -- but you've already addressed that amply with yr system.

Of course, active spkrs are an *extremely* good idea... indispensable in many ways.

Finally, as we all know for having toiled endless hours, (L+R) speaker placement is primordial -- we fiddle for hours and suddenly, finally, low frequency energy appears out of nowhere... The stereophonic coupling/image is an important base for the multichannel setup too.

Finally, if you wish to use dsp, you gain control over delay and phase issues, at the expense of some resolution unfortunately. These two aspects of control are far more important than FR equalising (i.e., the act of re-equalising & re-crossing yr spkrs) IMO. But there is that as well.

Cheers

“every time you play a song, it puts wear on the record which affects the sound quality”

True in theory I guess, but I have LP’s that have been played thousands of times and they sound as good as ever - zero indication of any wear whatsoever. I have also never worn out a needle - a few had been broken by an ex with careless dusting.

I would say the advice that guy gave can be classified as an Eddie-ism.

Analogue is a lot more bother than digital. You need to consider that it will take a lot more actions to listen to music than digital requires.

"What is the difference between movie sound and music sound"

Case closed ...

Hey Matt54321: Thanks for that. I have to put the hobby on hold for awhile because I moved into a new place, of course good old Security Deposit and first months rent has crippled the finanaces for this month. I was talking to one guy who told me not to go to Vinyl because he asked me how many new releases are being released onto vinyl and he also told me that with records, every time you play a song, it puts wear on the record which affects the sound quality. I guess he meant that the needle wears out the record a little everytime you play it? , dont think I have heard of this before? Has anybody else?

Greg,

As you can imagine I have a motive for my question and I appreciate what you have to say. Maybe your post will help
me clarify what I want from my question. I want the fundamentals on how I can buy a "live" real music lovers system. When you say low noise floor what's the signal to noise ratio 50DB, 100dB, and high dynamics what dB do you suspect would cover "high dynamics" in a medium sized room. Because I need to be able to shop for that "low noise floor" and "high dynamics" as Raul pointed out you can't even trust a dealer with a $500,000 system to do it correctly. So it would be great to eliminate some of the possibilities before I go shopping.

As you highlight I think it is erroneous to think a recording will sound "Live" with out manipulation in someone's listening room. But what is that magic manipulation? Raul's got it and I, m hoping he will share to elevate me to his level. I need to be told what to do with my system to make it a Real music lovers system, I think I have a pretty decent two channel system but i could be doing it all wrong.

"A reasonable simulation would be very low noise floor & very high dynamics..."

Would you feel comfortable saying that the equipment I have listed would or would not achieve this?

Cheers to Gregm, a voice of reason.

To those debating multi-channel and 2-channel, would it not depend entirely on the recording anyway? If I have a piano and a cello playing in a small room similar to the one I sit in, the instruments resemble the point sources of my speakers, in which case, if the recording is close-miked, my listening point in my room will resemble the place I might sit in the room with live music. In which case the reflections of the performance room match those in my room, which means I have duplicated the live experience quite faithfully using a two-channel set-up. And if my room is bad, then I have listened to a stellar live performance in a really bad venue, I won't necessarily do much better with the same thing in my room.

By the same token, I like the concept of multi-channel for the idea that reproduction of the ambient reflections offers spatial cues to give you a "you are there" feeling. That said, it would obviously work best on recordings where there is non-negligible ambient/reflective sound, and is probably best reproduced listening nearfield in an anechoic chamber. As I am neither convinced that most 2-channel recordings contain equal ambient cues, nor do I happen to have an anechoic chamber at home, I will stick with my humble 2-channel digital and analog system which pleases me just fine... though I am sure I could use some bass traps... :^)

...what exactly is needed to make a system sound live

A reasonable simulation would be very low noise floor & very high dynamics...
...but, OTOH, I don't expect a system to sound like live music. Live music would not be my reference (as it isn't yours). Rather, reproducing the medium would be a better /more reliable and palpable reference point.

In the rare cases where a reproduction is such that it creates spontaneous involvement, there is some magic. Sometimes, when the Gods are smiling, there is a lot of energy coming out of my spkrs (relatively speaking, of course) and the effect of a live recording (even average recordings) is lovely.

Raul - Due to reasons beyond my control, in order to discuss the topic at hand further, shoot me an email.

Thanks

Raul,

Why don't you tell us what exactly is needed to make a system sound live.

Give us the information that will allow us to experience what you experience.

I need to know which cartridge on which arm and which turntable you can assure me this experience will happen for me.

Live sound is the reference so it should be quite easy to design a system to do this. What are important speaker characteristics that you feel is essential to reproducing live music in the home.

Which record labels produce viable recordings.

Explain to me what makes and amplifier more musical for the REAl music lover like myself?

Raul where I come from the source is the reference and I hear enough live music and real instruments to be an expert like you so my piano lesson and season tickets to the Baltimore Chanber Orchestra etc. have served me well. As you know now that its 2006 its hard to find performances that are not amplified and or do not use electronic instruments. Please from now on don not assume I am deficient, I am an audio professional, not a hobbyist.

Here's my current two channel system tell me where I need to change components and why please; Cause its not better than my surround system based around the same speakers.

>>Check out Sergeant Pepper on Wikipedia for an example of severe messing around in stereo....<<

I kinda doubt George Martin and the band were really thinking about us audiophools when the album was mixed down. IMO of course.

Musicaudio,

Coming from a recent vinyl convert here is my limited opinion. I recently purchased a vinyl rig which cost total (cartridge, phono pre, and table/arm) less than half of what my digital rig (marantz SA-14) cost. Not that it necessarily matters but my vinyl rig is the marantz tt-15s1 for comparison. Anyhow here are my thoughts about your question. Before I purchased my vinyl setup I was looking for a new preamp. While in several different high end shops I decide to listen to a few turtables. The first time I sat down I listened to dire straits money for nothing. I got goosebumps. I have NEVER had this reaction to any equipment I have auditioned. Needless to say I quickly decided that I must get a vinyl set up. It is now about 8 months later and I am still extremely happy with my decision. Direct CD to vinyl comparisons in my rig always lead me to the same conclusion, that the vinyl is just more real and lifelike. I will say this. The vinyl is MUCH more work. In other words the records themselves really seem to very in quality as far as the recording itself. So you have to spend some time learning about labels, early pressings, 1/2 speed masterings, etc.., etc.. these make a huge difference in sound quality. You will need to clean your albums, much more maintenance than CDs. My suggestions would be if you don't mind the search/research on albums and don't mind cleaning and maintaining the vinyl then go for it, I think you will be rewarded with the effort. If on the other hand you want to just pop in a CD and listen to the music then stick with the CDs. I have no problem enjoying either format tremendously, but given a quality recording on vinyl you just can't beat the goosebumps that I still get IMO anyhow.

Taking a Doors tape and mixing in in 5.1 does not change how it was recorded. Music can be gimmicked to sound surround when it really isn't... No one is fooled by this kind of compromise!

This is such a true statement....gimmicked sound is not good, Depending on the master tapes it may be difficult to get something decent in 5.1 if the studio recording was not planned that way (for example you don't have all the separate tracks for each instrument/microphone).

However, not many people realize the amount of "gimmicking" going on in order to produce good stereo sound and a good stereo image. Artificial reverb and the like is almost always added to certain tracks. Voice is often doubled. Check out Sergeant Pepper on Wikipedia for an example of severe messing around in stereo....

"I'm all for surround in my HT system, it's great with movies.
It's just not for music."

Explain the difference?

Seems that struck a nerve, so I'll explain. I do find that surround sound helps to place me in the movie scene better. I'm on the beach in 'Saving Private Ryan', etc. However, I always found it uncomfortable when listening to music. I went through the surround sound phase for a year or so about 6 years ago. Trying high end pre/pro's from Proceed, Classe, Anthem, etc. Yet the music just didn't sound right. Maybe if you are trying to recreate the sound of a Dance club and be 'in the middle' of it, this is the way to go. If trying to recreate a live orchestra, it doesn't work. I want the orchestra performing in front of me, not all around me. I also found the center channel to throw off imaging, not inhance it.

The biggest hurdle though was tonality. No, I have never heard a receiver, or pre/pro for that matter, recreate the natural tone sound of an instrument as some high end stereo gear. I also find that vinyl is better suited at recreating this natural tone than digital. Strings are the best example of this. To me, massed strings sound congested and edgy through even $10K+ digital systems. A receiver or pre/pro may not be revealing enough to show this though, as many of them digitize the signal anyway.
FWIW, Digitally Mastered LP's also suck at recreated massed strings and instumental tonal colors, IMHO.

You really think your VA's and BAT gear are THAT much better than my surround receiver? How's that Judas Preist song go? "tell you right now, you got another thing comin'"

While I'm honored that you are researching my equipment, I guess I must admit that no, there isn't THAT much of a difference if Judas Priest is what you're listening to.

I KNOW my system can play orchestral music as well as your two channel system. maybe i'd have to use the $1500 receiver just for a safe discerbable margin. You own BAT gear and all the limitations of that BAT gear...fact

This doesn't even require a response. If your receiver sounds good to you, you are fortunate indeed, LOL.
'nuff said.

When watching a movie, I find myself distracted by the video screen, so musical tonality is not as big an issue here. Especially since music tends to be digitized and in the background of the dialog in the movie.

If digital, receivers and pre/pro's make you happy, count your blessings. I have friends who are perfectly happy drinking a Budweiser. I much prefer a good micro-brew. It would be great if a Bud tasted just as good to me, it would save me a few pennies.

You, Cd and Shardorne are welcome to your opinions, as long as I'm entitled to mine. It does seem as though you are lost in this forum though. You may have an easier sell with the surround/digital package of ideas in the digital and/or video forums as opposed to the analog forums.

I normally write IMHO (In My Humble Opinion) in my responses. I stopped doing that in this thread because you all haven't quite grasped that yet. You are more than welcome to your opinion, but don't try to force your opinion on others by calling it a fact. Published DBT results don't mean much to those that don't belive the method is valid, and no I won't get started, it also is a waste of time to debate this.

I find it hard to believe that you cannot see how pointless this all is. You will not convince me that digital/surround is better anymore than I can convince you that analog/stereo is better. Obviously neither one of us is a weak minded sheep. So again I ask, what is the point? I almost feel like I'm back on Audioreview.com arguing cables, DBT's and other meaningless nonsense. Not that your opinions, or mine, are nonsense. It's just that the argument never ends, and no one changes their mind. It just seems to me like a dog chasing his tail. I'm done chasing my tail, feel free to try and convert analog purists to your digital/surround philosophy. Let me know how you make out. :)

Sure, there are some that can sell snow to the Eskimo's, but you three aren't the ones.

Peace out,
John

I'm not real bright but it seems to me that the means of reproducing the music should be the same as the recording. I do not mean by that digital v. analog(remember that question?). Movies are recorded in Surround Sound while music usually is not. There are newer notable exceptions.

Taking a Doors tape and mixing in in 5.1 does not change how it was recorded. Music can be gimmicked to sound surround when it really isn't... No one is fooled by this kind of compromise!

All things being equal, I still think speakers are the least important link in the chain.

Shadorne - very well put. Bravo!

I'm all for surround in my HT system, it's great with movies.
It's just not for music.

What is the difference between movie sound and music sound? Many movies contain up to 50% music. If it is realistic for a movie than why not for music. Have you listened to Amadeus in 5.1?

I will grant you that there is a drawback to surround....it is extremely expensive to get the same level of quality as in two channel. This is very simply because you need FIVE high quality speakers (and sub) instead of two.

To me this is the crux of the problem with surround; it is roughly three times as expensive to maintain the same quality timbre matched speakers compared to a stereo setup. If a good set of main speakers are $10K, then a similar quality surround system will be at least $30K. Most people compromise and don't even get matching speakers (or sub) and, no surprise, they find the comparison of surround to stereo is unfairly biased towards stereo. Our ears are not fooled...you need the same quality matching surround speakers to get the full advantage of surround....or else all you get is special effects.

It's just not for music."
JMcGrogan2, Raul and everyone, for that matter - This is what’s wrong with me. This very statement and those like it. This statement concludes that it’s just not possible. In fact, many have said it in previous threads. However, this statement is a matter of opinion. Nothing against that, at all!

My argument is "what if it can be for music; what if it is for music? What if you can configure the system and processing to accurately reproduce the music to match the original recording?" I have yet to hear anyone ask how! Ok, so you don’t care, but what about those who do? What if some other than yourselves wanted to learn something new or just see what the stir is all about? What if someone wanted to honestly give surround a shot?

On the flip side, what happened to trying to answer the original question? Then again, I guess I’m getting side tracked. Go figure.

My problem is I've had the opportunity to hear a surround system, valued at approx $6K, namely D_Edwards', that brings out the best in 2 channel music, every single CD and digital track it played. So much that it surpassed multiple $150k+ LP systems, and numerous other high end 2ch systems that played a different version of the same recording. These systems where just like system many of you own. Many also exceeded your systems. I have nothing against those systems. Again, to each his own.
But whatever happened to listening for yourself? Whatever happened to taking the time to listen? Isn’t that what the hobby is all about?

Sure I only have my opinion that surround is better. But my opinion isn’t based on opinion. So then why not find out to see why "I'm wrong." OK, so you don’t care, but, again, what about those who do? Instead, the name calling and attempts at mud slinging begins. WHY? What was the point? What did it accomplish?

Truth is gentlemen, the research has been done. If you choose not to accept it, that’s fine. But that doesn't negate the fact that it was done. Another truth is the information is in front of everyone, available to be tested and investigated individually. You may have to do you’re your own research. However, no one has made an effort to do this. This is one of the many sad parts.
Is anyone prepared to listen? Is anyone prepared to test D_Edwards’ thoughts and findings for themselves? Is anyone even willing? If not, then how can you say “your wrong and I’m right” until you all are willing to prove why and how? Otherwise, audio is chasing its tail for the next 5-10 years.

I’ve been serious about audio for about 3 years now. Yes, only three years and no I’m not so new that I don’t know anything or any better. I’ll establish my point further in a minute. Anyway, I’ve been researching hard and met a guy who hipped me to DIY. He was my reference for a while. I learned so much from him. Then I meet another guy who introduces me to D_Edwards. Since then, I’ve been forced to think outside the box and for myself. I’ve been forced to conduct trial and error and been shown what to do and why, all at the same time. This led me from 2CH initially (yes, I did start out with 2CH) to MC surround. This forced me to pursue the truth of audio, not just an opinion.

Gentlemen, I apologize for allowing my enthusiasm to overtake me at times, but this is who I have become. An isolated, pursuer of audio truth within the realm of audio reproduction, be it 2Ch and MC. That’s my problem!

This is one of the many things I’ve learned in 3+ years.

“What is a phantom speaker?”

It’s the room. How? In the shortest way, your speakers emit full range frequency from both the front and rear. There are speakers that emit so much that the rear cabinet frequency reflection, combined with the rear wall, reverberates the reflection around the room. Many times, causing the reflection to bounce off of the opposing rear wall, so much that it gives the illusion of rear channels/speakers. This explains why many 2Ch guys say that they can achieve the same results as a MC system, from only 2CH’s. But from a technical/theoretical outlook, aren’t you listening to 3 speakers? ; )

On that note, let the rebuttals and name calling begin!
Happy Listening Gentlemen. This time, I am really done!

Why don't we all chip in to cover the cost of a Dale Carnegie correspondence course for Dead Ward?

I'll toss in a buck. Anybody else?

"I'm all for surround in my HT system, it's great with movies.
It's just not for music."

Explain the difference? If the movie is about the Doors and or Beethoven, why don't they switch off the surround sound when the music is playing if music is more "realistic" or live in two channel? I know filmmakers and if this was true they would do it. What say you?

"Stereo is so much easier, " yes it is...and the conceptual root of this debate.

"Been there done that. I went through the multi-channel phase several years ago, didn't like it. It doesn't properly represent a live orchestra. It felt like I was sitting in the middle of the orchestra instead of sitting in the 10th row. Listening from the audience is a more natural experience, fact."

Should have learned to actually use the equipment so you could listen from the 10th row, fact is you never came to fully understand all the adjustments you can make.

All I have to say is if you buy a proceed PAV you get what you paid for and its not a music surround processor.. As for your surround music experience according to you, you never had it running so "been there done that" is a stretch. Saw it bought that, then sold it...that's more accurate

"It is however still a receiver, with all the limitations of a receiver, fact."

You really think your VA's and BAT gear are THAT much better than my surround receiver? How's that Judas Preist song go? "tell you right now, you got another thing comin'" I KNOW my system can play orchestral music as well as your two channel system. maybe i'd have to use the $1500 receiver just for a safe discerbable margin. You own BAT gear and all the limitations of that BAT gear...fact

So please refrain from acting like you have any serious experience with surround.

GregM, you are absolutely correct. As the intrinsic goal is not realism, but hyperrealism, there will be of necessity be as many optimal versions of it as there are audiophiles, or at least broad schools of audiophiles.

Guido notes:

In some sense, the most musically satisfying reproduction system is hyperrealistic, rather than simply realistic.

That is a marvellous way of putting it (IMO, YMMV, etc, all politically correct injunctions). I would add that the flavour of hyper-realism can and does vary to a certain extent from one audiophile to another -- but particularly with fashion/latest trend in reproduction.

If surround was not more convincing than stereo, then big movie theatres would never have adopted these expensive systems...
Shadorne (System | Reviews | Threads | Answers)

I'm all for surround in my HT system, it's great with movies.
It's just not for music.

Raul;

congratulation on pleasing the frustrated crowd, your arguments and then attack are very amusing. A little contrived but none the less funny.

Your complete dismissal of digital isn't going to look to rational when this debate gets broken down. I think you slid past common sense there buddy.

Once again i'm not having a fight about analog and digital my fight is surround versus 2 channel. And you have no real experience with that Raul, so i don't know what you're so fired up about?

See if you read your post you have to assume that I'm somehow effected by your bluster and stuff, but your focus on digital versu analog really isn't my concern. My surround system is better than my LP playabck system, no contest. You could say that in your case its the opposite but you don't have a music surround system. So I'm afraid till you get one, you're going to have to take my word for it. Its very musical and live sounding.

From one true music lover to another

I am surprised by the vehemence of the arguments against surround sound. It is patently obvious that surround can create the ambient sound of a real venue better than two channel. Two channel can add cues using special techniques in the mix but it is just not as convincing as surround. If the majority of the sound is coming out of the left, right and center channels it will be close to stereo anyway. I think most audio engineers are more comfortable and still better at producing two channel stereo mixes.....but it is only a matter of time before they become as good at multi-channel as they are with stereo....and then multi-channel will begin to consistently surpass stereo for music, IMHO.

If surround was not more convincing than stereo, then big movie theatres would never have adopted these expensive systems...

“BUT any room noise and reflected sound arriving back at the microphone out of phase will be compressed into the stereo sound field (effecting its spectral balance) as noise when played back in (unprocessed) two Channel.”

Economical with the truth aren’t you Eddie?
Economical with the typing

1. The very same signals you refer to is present in all recordings, mono, stereo or surround. Multiple pickups in recording simply exacerbates the problem (And no, reflected signal the cannot be ‘mixed’ away as you seem to elude to - the same way sibilance cannot be removed without harming the original signal)
++++Thanks for making my point, it can't be mixed away but it can be separated from the front stage with an algorithm, funny we seem to agree . That sibilance thing is unrelated, tell your friend.+++++

2. Out of phase signals are not necessarily noise, they occur naturally and nobody on this planet has ever heard sound without some out of phase signals and harmonics mixed in. If fact, sound would be unpalatable without said signals
+++++No but information like the crowd clapping and shuffling, long hall delays that are uncorrelated in a live or large soundstage recordings are not out of phase but actually real sound that is uncorrelated. When only two channels are used, they get smashed in the main presentation. Please include digital/artificial heavy reverb and delay times used on vocals etc in the recording process. This information is distorted by the two channel system. To me this is a big culprit to the bright or sterile sound digital typically has in two channel, when you add it to the absolutely flat response of a digital source it does not take much to tip your spectral balance to the lean side.+++++

3. Reflection, reverberation and refraction occur at both time of recording AND reproduction i.e. artificially creating a “Hall Effect” does not prevent the refraction occurring naturally to your listening room - at the very best you can try and ‘drown out’ naturally occurring reflection with an overly loud out of phase signal to create the effect. Sorry lad, my ears are not fooled by that.
+++++Well actually, in like the 70's that's how you might do it, but your assessment of how the multi-channel system performs in room is a bit pedestrian and oversimplified. Fact is multiple speaker do create multiple reflections BUT their differential placement and the fact that each individual speaker has lower acoustic output minimizes the effect we perceive on the "direct" sound found coming from front stage.+++++
+++++A two channel sytem based on my own measurements has a much higher ratio of reflected sound than direct sound at the listening chair, but I moved before I could really nail it down scientifically.++++
+++I was researching swamping the room’s reverberant tone/field? with the surround system. I need that Bob Hodas measurement tool he uses, to measure the "room" with the resolution I need to get a room signature. BTW My idea of surround is not relocating the soundstage as you might hear it on a two channel system, I'm just talking about moving some information around that is not necessarily key to the recording to give the sound the rich and real life sound like an LP has and you enjoy...so i still don't understand what the problem is for wanting that? In this argument everyone goes for what digital does bad, but sometimes what is bad maybe because of an attribute it does well. LP's have terrible channel separation, thus they give you a denser center image with only two speakers...stuff like that. A bad trait, being good for the sound.

4. Signals more than .4 sec out of phase is perceived as an echo. Shorter than that, they can be quite pleasing to the ear, and can add a richness to the fundamental. Since sound travels at 1130 feet per second, my room physical dimensions and absorption levels prevent harmful reverberation very well.
++++feet per second at 70 degrees sea level.....
And what is the point here? is this my small room acoustics lesson 101. Everest is the man!!!!!! LOL+++++

“Pauly, what i'm talking about is not something you're going to "get" intuitively”

That is quite obvious ... what is also patently obvious is that you have little familiarity with live music.
Really, and you've been watching me? So the guys at Telarc are just frivolous and arbitrary, because they don't know what live sound is. I've been to many live concerts and recitals, its not that hard and I'm not afraid to go. And lets not forget my piano lessons. So I have easy access to all of your "qualifications"...btw ever hear of the Peabody Conservatory? ....

“The information is not on the web”

Why am I not surprised by this admission? Of course it isn’t, because your interpretation of said document is more than likely patently ‘unique’.
You shouldn't be surprised, the research was done in the 60's....you can't even get Ngarchs MIT '65 paper on the web. Why don't you take the THX class? So don’t make it my fault that you don’t know this stuff already and have to look it up to see if it exists. You’re the ones who’s got no backup.

_____I think herewith lies the difference between us. My audio system is put together to reproduce live performances as closely as possible. It is not designed to impress or who people. Non audio folks are not impressed.______

First of all can you tell me what exactly is so impressive about adding rear and a center channel to a system? Why in your mind am I trying to impress people, wouldn’t a big plexiglass turntable on top of my riack do a much better job for the WOW factor? Oh before you answer, the turntable works everytime…
My system is designed to play the recording accurately no matter what the subject matter, do you see the graphs on my cheap system? My little crappy system is +/- 4 dB with 8th octave resolution 30hz to 20khz.. With DSP correction my ATC system was +/- 2dB at the chair. At 100dB! Actually more a room acoustic pat on the back. --- as we have already discussed my two-channel system is atleast equal to your system. And since you have no surround system it looks bad for you when it comes to integrity on this matter. I can't even tell you what I'm doing so you can try it. How dishonest is that? My system is designed to impress me, that is lot tougher than some audiophile or non-audiophile..
The names Doug; and that's it. Get a surround system and we'll talk, otherwise I'm just debating someone’s who's speculating and guessing about something he doesn't have well atleast you have some help with basic acoustics.///.

Pauli and all, I still contend that the question of superiority of digital over analog is not only undecidable, but is likely meaningless and a false one. I grew up in Milan with the live music of the Teatro Alla Scala. I have listened to live music. I have performed live music. I have been in modern concert halls, in big and small theaters, in cathedrals, in country churches, in school cafeterias, under mideval porticos. I have sat on the banks of the Cam, while Handel's Water Music was performed on a barge. I have listened to acoustic music in piazzas and in private parlours and coming from the bandstand of Blackrock park in Dublin while I was sitting on a bench in the rain.
Now, as an audiophile I own a high end digital system, but have also listened to a lot of analog gear. Under no circumstance, I have heard any system -- analog or digital alike -- that can be deemed 'life-like'. What I have listened to is a wealth of atrocious music reproduction, from both types of front ends. And a few marvellous music systems, from both types of front ends. However, even the 'marvellous' ones, do not sound like live music. They sound different, both somewhat worse than those live venues that I have attended, and simultaneously a lot more musically satisfying than those same live experiences. Certain features of the music remain depressed or are slightly distorted, while others -- equally crucial ones -- are enhanced. In some sense, the most musically satisfying reproduction system is hyperrealistic, rather than simply realistic.. This may sound like anathema, but if our goal were to create beauty, instead of mimicking some narrow minded perspective of physical reality--the current rarely high achievements of both analog and digital--if admittedly different--are not bad at all.

Too me two channel is a joke, fact.

D_edwards (System | Answers)

To me multi-channel is a joke, fact.

Been there done that. I went through the multi-channel phase several years ago, didn't like it. It doesn't properly represent a live orchestra. It felt like I was sitting in the middle of the orchestra instead of sitting in the 10th row. Listening from the audience is a more natural experience, fact.

FWIW, feel free to hype how great your receiver sounds all you want.
I'm glad it makes you happy, fact.
It is however still a receiver, with all the limitations of a receiver, fact.
I'm sure you opinions would be much better 'received' on Audioreview.com, fact.

Nice job Raul.

The emperor has no clothes.

Dear D_edwards: +++++ " my goal is zero compromise " +++++

This is not a serious statement when you are talking of digital technology. Period!.

Not big deal, very often the audio dealers have a wrong set-up. Period!!.

I was wrong when I assume that you were a knowledge mature audio/music person digital oriented, but no you are like so many thousands and thousands of people that think that have the " bible " on its voice and forgot that they are only " one single person " with great limitations ( like you ) and that God ( yes, you certainly are not God. Not even the audio God. ) is far far away from them. Period!

Btw, I ask you which is your sound reproduction reference and your answer was: dead silence. Period!

I give you one FACT ( there are many of them ) of the today ( two channel or multichannel ) digital limitations: 16/44.1 with a limited real frequency to 22.05kHz, your answer about: dead silence. Period!

"Phantom speakers? What is a phantom speaker?"
:)

So listening to a live recital, the piano can only create “half a circle” and the rest “collapses into noise”?

Dude learn to read a little closer, your commenting on a excerpt that is talking about the 360 modeling used in creating digital effects used in all modern digital processing , delay and reverb etc.

BUT any room noise and reflected sound arriving back at the microphone out of phase will be compressed into the stereo soundfield (effecting its spectral balance) as noise when played back in (unprocessed) two Channel.

Pauly, what i'm talking about is not something you're going to "get" intuitively, you're going to have to read some stuff and experiment(tvad). You're looking for a easy way to dismiss what i'm saying but your comments do not seem to project that you grasp what i'm talking about.

The information is not on the web, THX will gladly charge you for the course and NEJM will be at your university libraries. What I don't appreciate is you feel you can engage me with so little information. I would think you would have read these papers/articles for you to be so strongly opinionated. We are not discussing my mis-representation or misinterpretation of the facts of these studies. You are telling me they don't exist!

PS: Pauly why don't you read the MIT paper Nsgarch posted a link for and tell me what you think. Lets start there. Tell me if that is what needs to be done to two channel audio to get it to work like a surround system.

A. Why bother, when you can use the natural decay of your listening room to reproduce the natural decay on the recording already.

"Where did you get that silly notion that sound reflection and refraction should occur naturally when you can have it done artificially? ;-)"

I can extract that from your comments.

B. Why does so much information require deletion, and how is this similar or dissimilar to what i propose the rear channels do in our current Prologic 2 setup?

Raul, my goal is zero compromise, you should talk to the several hundred people who have my systems about what music sounds like to them, they disagree with you and many of them are musicians.

Want to know "what's wrong" with CD wallace? He heard my little receiver system and despite going to all the stores in DC and Baltimore, not one store has a two channel system that is as musical. So like many of my visitors they are isolated with an experience that is unique to all of you. Sorry you all can't come over.
---------------------------------------------------------
The sound was impressive but something ( for me ) was not right: why I been exited but not emotional?. Then I return to my reference ( live MUSIC ) and how I percieve it in a live event:

Hey Raul, why didn't you go make some adjustments till it did sound like live music to you?

LOL! buddy that's all I have to say. Surround is not analog you're not stuck with what it is you initially hear!!!!!!!!

I have owned great LP playback systems and still do, so I know what LP's can do. Lack of knowledge and experience is never going to be the right answer, so you guys need to quit going there.

Building a phonostage is not rocket science, I can do that too AND have. So Raul buddy, next time you have the chance ask the people to adjust the surround to your tastes.

"exited but not emotional"

As for your emotional response and involvement, that's a psychological problem when everything you thought you knew evaporates in an instant. Being wrong is not conducive to feeling good.

I have guys who don't talk to me after their little revelation, and the way that I get them is I have them listen in surround when they think they're listening in 2 channel, then I switch the surround off.....blatt, all of those nice things they had to say suddenly change. I wasn't emotionally involved....please, like you can get emotional at a dealers showroom?

Sorry nice try raul but I'm not even working up a sweat over your assessments. they're not even new.

Shadorne if i came to your house and adjusted your system, you wouldn't have time to write on here anymore :)

You're a Meridian processor away from eternal audio bliss. love your speakers.

Dear Cdwallace/D_edwards: It is clear that you are in love with multichannel and digital technology in a fanatical way. I like your passion for what you believe, well done. I respect both of your opinion, as I respect any other single opinion here.

Now, I'm not a fanatical about any technology: digital or analog, tube or SS, two channel or multichannel. I'm a music lover and a fanatical of MUSIC: live music and this is my reference.

Through your post I can't see/understand yet which is your reference: live MUSIC or technology/audio devices?

I'm in the analog and digital electronic design for many years and I can talk of facts on either technology for " years ". But the experiences are part of those facts and I want to share with you some of those experiences:

more than a year ago, in a business trip to Seattle, ( by coincidence ) I had the opportunity to heard the best of the best in multichannel systems ( at least I never heard something better till today ), this was with a dealer there ( Definite or Definitive Audio ), one of the dedicated room ( multichannel ) had all Wilson speakers and Halcro electronics and I think that the processor was Meridian or Lexicon, I can't remember, the room conditioning ( I think ) was designed and build by Rives Audio or some at that level. The front speakers were the MAXX2 and the surrounded WattPupy7.
In the past I had the opportunity to heard a few multichannel systems but nothing near this 500K all asault system!!!

From the very first musical note the sound was impressive, for say the least, I can't belive what I'm hearing!!!
I'm sure that with this very high quality level of demo many of the people that attend that time were " catched " and bring that technology to their homes.

The sound was impressive but something ( for me ) was not right: why I been exited but not emotional?. Then I return to my reference ( live MUSIC ) and how I percieve it in a live event:

I attend every week at least at two live events, classical/jazz,. I sit in the classical hall in the 4-6 center row: in all of the more than 20 years that I attend to concertos I never experienced the impressive " fake " of that multichannel demo or at least I never had the capacity to heard it: the sound in the hall ( where I sit ) is direct, there is a little ambience but nothing near the multichannel ( i don't want to use the " fake " word and I don't know other one ).

Now, when I attend to a Jazz club ( that normally has not avery big space ) the musical experience is more dramatic than in a big classical hall: you have the MUSIC in " front " of, what I say? not only in front of you: the musical notes hit/crash over you, you can't heard the musical ambience or it is at very low level over the direct sound.

All my MUSIC live experiences tell me that till today the best way to hear the music at home is through two channel, this is the way that put me near the live event. May be in the future the multichannel could be less " impressive " and could put me nearest to the live event and could give me the " emotions " that the two channel do.

Of course that the " music power " has no barriers of any kind and when we heard a song/melody/tune that we like it, it does not matters if we are hearing in the car, at home or by headphones we feel how grow-up the emotional feeling in all our body and this FACT is all about!!!!

I assume that you ( both ) feel in a better way those " music feelings " through the technology that you support and that's what counts to you.

Now, I agree that digital technology has a very good future but the analog technology too, let me explain it:

one of you posted that the analog technology have no advances in the last 30-40 years. I think that you don't have the right know-how about. We can take any analog area/stage: TT/tonearm/cartridge/phono stage/etc and I can prove to you that the analog technology has a very good advance ( with out any manipulation ) and in some areas a great advance today against 30-40 years ago.

Now take a look to the digital ( per se ) technology: TILL TODAY IT IS THE SAME ONE THAT WHEN START: 16/44.1 !!!!!!

this 16/44.1 was and it is the Aquiles heel of the digital technology. There are many facts against why the digital technology is so far away of the live music, I'm only give you one of them: the frequency response stop at 22.05kHz against the analog technology that goes in a more natural music way a lot higher than that. All the digital manipulations that that technology was suffer over the years ( to be near the analog sound and in this way to be near the live music ) like the up-sampling: 24/192 ( Redbook ) helps this technology to be accepted for real music lovers ( like me ).

Now, unfortunatelly the SACD/DVDA digital technology, that is a real quality sound improvement over the " glorious " Redbook, was " killed " from the very first moment that was created and was killed for their creators. This fact is a very sad one because the SACD/DVDA technology is very close to analog in some areas, even in others and is superior in other ones.

It is clear to me that in today audio/music stage the analog is a different and superior way to hear the MUSIC.

Well fellows this is my humble opinion about, just an opinion.

Regards and enjoy the music.
Raul.

D_Edwards,

I am not sure if surround is currently better than two channel for music but I don't doubt it will eventually surpass. I think the engineers are not all able to put out consistent stuff for music at the moment. Multi-channel should give engineers tighter control on "ambience" & reverb.

What I have observered, so far, is that movie surround sound, particularly stuff coming out of major studios with a big budget (productions from skywalker sound and the like) are absolutely SUPERB. Far better dynamic range and recording quality than the majority of CD's. These multi-channel sounds (voice, music, or SFX) are some of the most realistic available today from any speaker system.

Part of the reason may simply be due to the adherence to standards of recording level in movie multi-channel. Twenty years ago, Lucas did a lot to promote one set of standards and these appear to be sticking. (Something sorely lacking in the music industry where there are sadly NO recording level standards!).

Another reason may simply be budgets (movies get to spend a lot more on sound quality)

Phantom speakers? What is a phantom speaker?

“draw a circle then draw a line dividing the circle in half, if the circle represents the "echo" effect on a drumstick strike your stereo system can only recreate half of the circle the rest of the circle collapses into noise”

So listening to a live recital, the piano can only create “half a circle” and the rest “collapses into noise”? Or by your definition, only a quarter circle, since a recital is mono. Will 4 Pianos will then have no noise, as it creates “the full circle”?

LOL, I have just “collapsed into” laughter ...

Scientifically proven. Its the information that motivated serious companies to spend serious money to try Quadraphonic, the boat anchor of home audio.’

Fact

counting on phantom speakers will never give consistent results like having real speakers. And there are other factors that profundly affect 2 channel playback of digital in a very negative way.

Fact; read the MIT paper posted by Nsgarch it is quite thorough at explaining how our current two channel setup is flawed.

draw a circle then draw a line dividing the circle in half, if the circle represents the "echo" effect on a drumstick strike your stereo system can only recreate half of the circle the rest of the circle collapses into noise. That noise is disproportionately high harmonics thus hi frequency, shift the balance of the recording.

Fact

The number of recordings that use no compression is incredibly small, like .001%. Compression is a signal to noise reality that must be addressed and not ignored.

Though the numbers may vary slightly from what I posted, that is a FACT.

You guys started in on me about digital and surround , and as you have demonstrated this area of audio is not your forte.

Fact

Mcgrogan; not being aware of the facts or refusing to acknowledge the facts does not make them opinions. This is the problem all along. I have studied and researched for 15 years. I am a film major, I have worked on feature films, I have recorded bands…etc. Believing another thing does not change the facts. Life is not that simple.
In my opinion I’ve never heard an analog two channels system that even comes close to a high quality surround system. And there are many surround systems that qualify. My opinion.

Too me two channel is a joke, fact.

Doesn’t matter if its analog or digital

Keep it straight dudes, I’m not anti analog, give me seven discrete analog channels on an open reel tape deck and I’m happy.

I just perused all of D_Edwards 'digital answers' and found no facts, simply published opinions. Seems the meat and potatoes are simply a cardboard photo.

So again I ask....what is the point of this meaningless excersize in futility?

Surely they must miss you at Audio Review.
