How Important Is The Cdp?


Hi,

My current set-up includes PSB Stratus Mini's speakers, Cambridge AZUR 540 A and a Toshiba 3950 DVD which i use for cd playback only. I know this is a mismatch of gear, but i originally hadnly planned on using this equipment with each other, then shortly after had some money troubles so im stuck with this gear for awhile.

My system sounds OK at times, its somewhat musical but alot of the time the sound is jsut too harsh and fatuiging- guitar harmonics are especially grainy and shimmery, vocals seem to be yelling at me way too much and overall the sound seems unfocused and veiled.

My room is pretty small, about 10x10 with an open closet and Jon Risch acoustic treatments directly behind each speaker, side walls arent really treated at all. I know my room isnt the greatest, but somehow i get the sence that the room isnt the main problem im having, sure it could use alot of improvement but the bad sound seems to be coming directly from the speakers.

Im sort of confused on what is causing the harshness, some people say its my cdp, others say my amp and then theres a few who think its my speakers interacting with the room.

This brings me to the question on how important is the cdp? Ive heard many people say that the cdp makes very little to no difference and wont tame the harshness i speaker of. Others say the source is most important and that what im hearing is my speakers producing the crappy sound my cdp is feeding them.

Would a better cdp, or say a 1000$ DAC improve my system to the point where the harshness i speaker of will be mostly eliminated, or will it just show more weaknesses of my amp. Or will a better cdp just make my system only slighty less harsh by only taming some of the digital glare of cdp's?

What do you guys think? cdp causing the harshness, or is it the amp?

i cannot, under *any* circumstances agree with gregadd on this one.

all the tube buffer does is further distort the output signal, by design!

if you like the sound of tubes, get a player with a tube output stage or mod your player to have tubes in the output stage. don't run the signal through SECOND output stage just to add the "tubey" sound to it. all you're doing is altering the signal by running it through more pathways.

remember: if adding something into the audio chain (other than maybe an upsampler, which at least has some theoretical benefit) alters the sound audibly, it is degrading the signal. period. the tube buffer cannot improve the signal it gets. it's like adding a pouch of dirt to the spout of your kitchen spigot - you may like the taste of the water that comes out of it - but don't say it's as pure as it was before it got there.

I tend to think that your source is very important, but this may not necessarily equate spending huge amounts of money, or even more money than you already have spent on your source. After all, a lack of experience with the source in question may result in the same sort of characterful sound that you are disenchanted with now-regardless of price or its reputation. Maybe it is more important to consider what sort of sound you are hoping to achieve with your system. I mean, What is better to you? There very well may be another cd/dvd player out there is tonally more in line with what you are looking for and that will hold you in good stead within whatever budget limitations you have set for yourself. Maybe not. However a little experimentation with the components that make up your system- those you can borrow, rent, or return, will yield results, regardless of price, and you will gain experience determining what is best for you- confidence in the real value the purchase you have made really offers you within the context of your system, when the time comes to put down some serious money.

thats where it starts,its more tolerable with mid fi stuff hooked yo as long as its at least half way good,and then using the best source you can afford.But believe it or not some say the source doesnt matter.

ck out http://cgi.audiogon.com/cgi-bin/srch_fs.pl $99 amp

put some felt around your tweeters on the baffle

get some cheap cotton prints and put a layer of polyfill above them then tack them to the ceilings and walls, or get some surplus wool blankets. make sure to mount an inch or two away from the surface so the sound can be absorbed twice, once going in, once going out

if you don't get the amp, put a resistor in front of the speaker to mimick the sound of a tube amp. you can cheaply fashion a zobel to short across the speaker terminals to get rid of noise above 20,000 cps. (yeah, i know the speakers don't go that high and you can't hear that high)

do the mods to the player
