Class D is affordable and sounds as good or better the SS/Valve why buy anything else ?
I have spent a fair amount of my hard earned money on big ticket brand new SS and VT/Valve amplifiers over the years without hesitation, with state of the art 2019 class D amplifiers becoming cheaper and sounding better, i wouldn't join in again.
For older technology amplifiers SS VT/Valve to compete with State of the art class D, Their prices are going up and up.
One example is Pilium Audio from Greece or Bulgaria their Divine Line the prices are all over £100,000 for their pre amps and power amps, I know the UK importer he said they sound OK,
Another example FM Acoustics again up to and over £100,000 for pre and power amps. i have owned FM Acoustics pre and power again their OK,
I am not saying they do not sound good, i am saying why spend this much when state of the art class D probably sounds as good now and can only improve with the GaN capacitors and is nearly up to 100 times cheaper.
Is there still a market for multi thousand £$s SS or VT/Valve amplifiers ?
When class D finally overtakes SS VT/Valves what will people do with their multi thousand £$ amplifiers, keep them knowing there is something better ? Or will we see the market flood with exotic used amplifiers ?
Digital technology is rapidly growing pace and becoming cheaper, with GaN capacitors being introduced the sound is going to get better and better and will slowly or quickly become even more affordable.
If you had 50,000 to spend on an Amplifier, would you buy a high ticket SS amplifier and hope for the best ?
Would you stay safe and go with high ticket valve amp, class D can never match good valves right ?
Or would you sit tight and see how the GaN capacitors can further improve the performance of state of the art class D ?
Please feel free to join in, everybody is welcome, i think its a very delicate/touchy discussion for some people with big bucks invested in older type amplifiers.
Regardless on what the cost is to build, if you're not getting a better product for more money it's not worth building. Which is why I went to market with the 1200AS rather than an NC-500 based amp. Even after 8 generations of NC-500 designs. And yes it is true that I set the price bar. I already had over 100 1200AS amps sold before anyone else started selling them. So how could anyone else get away with selling them for much more?
Anyways I thought you were releasing the best 1200AS based amps ever? I was just reading that you had a showdown at your place against a pair of my Purepower's and yours amps blew them away:
Your all in one DAC/amps are only as good as the weakest link. The stock 1200AS1 or 2 is not state of the art. And many would prefer a tube sound or whatever sound pleases them. Having an all in one gives up the whole idea of tweaking fun. Even if your DAC part is state of the art......your amp is not. Because you have one less interconnect does not mean much at all. I run a 2 foot hardwired balanced cable from the discrete output stage of my modded Oppo directly to my custom input circuit on my mono 1200AS1 modules. No preamp, no connectors....pretty darn nice. Your DAC looks fantastic, but I would not want to be limited to todays stock amp modules.
Simply not true about you having anything to do with the price of 1200AS2 amps being sold today. No manufacturer can sell an amp that costs them way less in parts and sell it for more than another amp they sell that has way more money in the parts......especially, when they are showing the insides of their amps and all can see. The 1200AS2 is a stereo module with built in power supply. The NC500 is a separate mono output stage that needs a separate custom input stage board and a separate power supply board. So, a stereo NC500 amp requires 6 boards that cost way, way more than one single 1200AS2 module. The companies that sell the 1200AS2 are just pricing them according to parts cost. You had nothing to do with it.....you just want a pat on your back....well, I applaud you for first telling everyone how good they sound. They are really great amps and especially when tweaked and run mono. They are not state of the art, no matter what you do to them. I am pretty sure a pair of AudioNet Heisenberg amps ($105K) would be preferred by most. However, for $2K....they are mighty fine.
The reason I'm no longer selling straight power amps is because today's best class D amps are not the weak link in everyone's audio chain. It's the highly inefficient signal chain everyone uses of DAC-cables-preamp-cables-amp that kills the quality. I have moved on to digital input amps, that allow far better sound than is possible with yesterday's way of doing things. No matter if you have the best class D, A, A/B amp in your system, you will not get better sound with yesterday's signal chain. So folks should stop focusing on amps alone and focus on how to get better overall sound from their systems. Another bonus of eliminating all of these expensive weak links is it drastically saves on overall cost as well.
If I mention a certain brand does that mean I am advertising it and must be promiting it. There is a lot of guilty posts on here if that is the case.
It's as good a topic as anything else here so don't get your knickers in a knot some of you. Technology advances. If you think something wont surpass tubes and SS at some point you are sadley mistaken. IMHO
I wouldn't buy a Hypex Ncore based amp before trying an Icepower 1200AS based amp. Just because the sellers of Hypex Ncore based amps are making higher profit margins, doesn't mean they are better. I designed the rev C NC-500 input buffer that made Nord famous, and several others are using as well. I shared all the details of the buffer design publicly on Diyaudio before Colin at Nord built his first NC-500 based amp. And after that I went on to building 7 more generations of even better amps based on the NC-500. However I only ever sold 1 of them, because I heard the Icepower 1200AS. The Icepower 1200AS module well implemented is still better than the best NC-500 based amp I've ever built. I've had about a dozen clients replace their Nord NC-500 based amps with rev C buffer and SI opamps with my 1200AS based amps. I even had 1 customer replace a pair of Mola Mola Kaluga mono's with a pair of my 1200AS based amps.
The moral of the story is don't judge quality based on MSRP. The 1200AS based amps on the market today would likely sell for 3-4x more than they do today if I didn't set the world wide price bar so low. I had the very first modules that hit North American soil on Nov 4th 2017. They arrived the same day the North American distributor got them for the first time. 1 week later I already had 66 amps sold.
I have sold over 200 1200AS based amps, and I'm no longer in the power amp business. So no vested interest here on my part. Just sharing some facts for those who are interested. You'll notice my amps sell for the same or more used than they did new. That should speak for itself about the quality.
The world is not flat, it’s round. Digital is the now and the future. It’s a very hard to change a paradigm when everyone’s background and context is SS and or tubes. But I switched from tubes and will never go back.
there will be a time when all smart designers will start making class d amps. I think it’s already is starting. In Five years we will have a huge shift. In another 5 the old amps will just be collector items. progress....
The simple answer is that some people don't agree with your hypothesis, me included. Maybe we are wrong, but that's the answer. If we all start with the assumption that class D is perfect, the discussion becomes entirely meaningless, except to a marketing manager trying to decide when old habits will die. IMNSHO we are not near that point, although Class D has certainly overcome many of its early teething issues. The NAD 3020D is pretty darn good - and that's actually a more meaningful accomplishment.
For the record, i know a fair amount about GaN, and am friends with some designer and fabrication engineers involved in it. Yes, its speed is useful in class-D, but the fundamental challenge remains the perceived sound of the reconstruction filter, which is very complex since the speaker is essentially an unknown to the designer.
I also do not feel that ANY design requires even $10k, unless one has some very special performance needs. The funny thing is that in my own designs, the device selected is one of the least contributing choices. I have used ICs, solid state and (to a lesser degree) tubes and achieved sonically very similar results - again with obvious caveats for tubes and tough loads. G
I have a Nuforce Ref 9 V3 Se mono amps w/ TDSS level 3 upgrades. They are class D. The standard Nuforce Ref 9 V3 SE amps already sounded very good. It is why I Iooked into the many Nuforce and Nuprime owners that were having their amps upgraded by Bob Smith at TDSS and were very excited by the results. For well under $4000 including the cost of the Nuforce amps originally, I ended up having them done and the result was now like having a pair of super amps for sound. It also made them more reliable than stock. I've used them in friend's houses with very different systems and speakers. In every case, the TDSS Nuforce amps made the best sounds compared to expensive and well reviewed amps they were using prior. The 2 mono amps are so small and light I can carry both under one arm easily. I happen to have a very good TRL DUDE preamp that is 75 lbs. of great sound. I was using VMPS RM40 BCSE ribbon speakers and they sounded great. Now, I have an awesome pair of Vapor Joule Black speakers and the sound is just off the charts fantastic in every way. I also upgraded my cables after hearing the potential of the Vapors. This was the last touch the made a very nice difference. At this point, following a 5-6 year plan I had, there is nothing to want in any way from my system. I will just kick back and enjoy the music. I had Edge and Bryston amps prior. They were both good amps but these with the TDSS upgrades are many rungs higher on the ladder of sound.
First off, price does not equal performance. Since I build components and upgrade them, I have yet to see the quality of capacitors, resistors, transformers that I use in any typical manufactured product past or present. Have you seen Caddock or V-Caps in any product built? I have heard a few Class-D amps over the years, not many but a few, and those did not sound better than my old Lafayette KT-550 tube amp, not even close. But I am open to try anything. So if you are saying the cost does not justify the means (sound) maybe you are correct. Even the Counterpoint products that I upgrade sound better than most of the components I have compared them to today. Go Figure! It comes down to the implementation of the design. For example, not all R2R DACs sound great. Not all Class-D amps sound great. Not all conventional components sound great. I also don’t like circuit boards with surface mounted parts. To my ears, they do not sound good!
A good digital amp such as the Gato Audio I use from Denmark is very good and uses modified Pascal amplifier modules ,then their own custom analog input,output sections. A Vacuum Tube preamp is a great complement to a good digital amp. you get the best of both worlds. Even in digital dacs and players hybrid tube , Solid state sound excellent.
There are many amps better than class d such as Auda Flight Stremento #4 mk 2 or Pass 350.8. These are just 2 examples.More body more weight and better detail than any class d.
Will only ever happen once those who know better die off, and the majority of the audiophile population is comprised of millennials weaned on MP3s.
What’s really amusing is that anyone would pay thousands for a class D amp. The modules are cheap. Anyone with a soldering iron can construct a class D kit amp that competes with the best of what that topology has to offer - which isn’t much outside of small size and efficiency. Those claiming it has surpassed competent A/AB designs should make an appointment for an audiogram.
If you think there is no difference fine. If you think there should be a difference a hearing test will allow you to discover why you can't tell the difference. If you have great hearing and prefer one over for any reason awesome. To try to stake a claim that one is better is futile unless you are just trying to up your post count and her yourself think.
I just want to chime in here that I don't believe amplifier class bigotry helps us.
I mean, if the goal is to get sound we are in love with for the least amount of cash outlay, talking in absolutes about any class of amp is not really useful.
I've heard terrible Class A I really really disliked, and great Class D, and vice versa.
The most important thing in my mind is for consumers to listen with their own ears and buy for their own pleasure.
I didnt find any GaN class D amps affordable, may be prices comes down in next couple of years. How good they sound, that’s very subjective and system dependent. Well designed class D (not using off the shelf parts) amps with good power supply still cost pretty penny.
Last time i checked GaN mono were retailing at $16K. And IMO, there are much better alternatives in Class A, A/B and Tube amplification under $16K.
The Benchmark AHB2 is Class A/B but the Hypex NC400 is Class D. And besides their output impedance (which is why they sound warm on ported speakers), a tube amp can also be just as good.
HI, Have a listen to the Nord Acoustic One SE NC1200 Stereo and see if that makes your main system, i own a pair of One UP SE NC500MB with REV D upgrade boards and Sonic Imagery OP-AMPS the sound is incredible at £2200, before hearing the Nords i had no interest in class D but so glad i heard them now. Approx 10 years ago I owned a pair of Edge NL Reference driving the Nola Grand Reference and will state what im hearing now with a much more modest system including Nord Acoustic class D sounds better.
I have never owned and never will own any of th0se super high $$$ amplifiers, so I can't comment on them. In my price range (< $10k), I have owned all class D, all SS, SS/tube, and hybrid class D/SS. First off, it is all a compromise. Even at the very top end where cost is no object, there are still subjective choices to be made. SS and Tubes can never have the efficiency of class D. Those that prefer tubes will never go SS or class D. Tubes just have not worked well in any of my systems (altho for my electric guitar amplifiers tubes are the ONLY way to go). Personally I think class D sounds very good, but is bested by good SS designs. For powered subs, class D is the best option. I plan on dabbling in class D again in the very near future (disclosure, my employer is very active in that technology, but not me personally, although I do have access to it). I doubt that class D will end up in my main system except as it is, powering the bass in my ESL/hybrid speakers.
