Class D amplifiers. What's the future look like?


I have a number of amplifiers: Luxman C900U, Bryston 4BSST2, Audio Research VSI 60 Integrated, NAD C298 and some other less noteworthy units. As I swap them in and out of my main system, I've come to the conclusion my very modest NAD C298 is about all I really need. Granted if I had extremely hard to drive speakers, I might be better with the Bryston or Luxman, but driving my Harbeth 40.2 speakers, the NAD is just fine. 

I thought a while ago that class D would quickly overtake amplifier design type mainly due to profit margin which I think would be much greater than A/B and tube. I'm not saying the other design styles would go away, just that D would be the most common style. 

Clearly my prediction is not panning out, at least in the mid and high-end audio world and I'm wondering why? It seems companies such as Bryston, Luxman, McIntosh, Hegel and so many others are sticking by A/B. I'm no "golden ears" guy, but is the perceived sound issue(weather real or imaginary) still holding D back? Maybe my assumption of profit margin is not correct? Maybe the amplifier manufacturers are experimenting with D, but keeping tight lipped until release? Perhaps brand loyalists don't want change similar to what happened with "new coke". What else am I missing?

The only thing that is real is what is experienced. Many have experienced the "latest and sonically best" class D as equal to or even better than class A. Check out the latest from Steve Huff, for instance. He thinks the pure digital class D integrated amp from Mark Levinson (Daniel Hertz company) is better than any class A he has ever heard. The Daniel Hertz amp is similar to Technics and Lyngdorf and Peachtree GaN1.....pure digital input, no analog stages, no feedback. Levinson has proprietary software that enhances all digital sources (so he says).

If you have not even heard the latest analog class D amp.....like my modded units....like Ralph’s amps.....like the latest version 3 AGD units, etc.....then how you can know what class D sounds like? Your opinion, for it to mean something, has to be based on direct knowledge.....(actual A/Bs in your system).....for it to be worthwhile. Otherwise it is just ego BS.

IF you want to be taken seriously.....you need to talk from direct knowledge of what is happening RIGHT NOW with the latest gear.....not what you heard before.

I "think" that pure digital input class D will take over the market. The modded Peachtree GaN1 ($1800 including mods) sounds really great and some people think the STOCK Peachtree is as good as their $12K+ stack....if not better.....stack meaning DAC plus preamp plus amp. What is so cool about these inexpensive pure digital amps is that you can use two of them and make your own bi-amped system like described on my website......so for around $6K you have the crossover, two amps....all the drivers, wires and baffle.....fully equalized, fully open baffle, planar mids and highs, no normal xover, no binding posts, no DAC, no Preamp, no normal amp...no analog interconnects,,,easy to build. What this would give you is incredible sound.....basically untouchable for the money.......two 12 inch woofers on the bottom flat to below 30hz.......OMG!!! Who will be the first to try this? I will help you do it.

There are more and more powered speakers with built in class d amps (including direct digital class d) coming out all the time. We have only just begun......class D will keep getting better and better.....and pure digital class D makes the most sense to me (less is more). I think a modded Gan1 ($1800) would keep up with the latest $3K DAC plus latest $3K preamp plus Ralphs amps ($5400) plus two interconnects ($500).....or basically $12K total. Now compare that 12K system (WITHOUT speakers and speaker wires).....to the $6K total system mentioned above that INCLUDES super seriously tweaky speakers........no contest.

I’m not sure if it’s prudent to quote Steve Huff to prove your point. 
Not too long ago, he thought the class A pass labs was the bees knees. Before that, Luxman was the best thing since sliced bread. Recently, he said Aavik was the best amp he had ever heard. Everything is endgame, “the last component I’ll ever own, will take it to my grave” as far as he’s concerned. 
 

how much do you want to bet he will have another endgame component three months from now?

Who are the people who think Peachtree is better than their 12 k systems?

While we’re at it, I want everyone to know there are folks who think their $500 class AB is at least 70% better than the modded Peachtree Gan amps. See how this works?
 

I like Steve Huff...As a human...

But his room has nothing to do with acoustic optimum...

As many reviewers he sell gear...

Not acoustic knowledge which is over any piece of gear the ground of musical experience in sound...

It is not your amplifier nevermind the class, you must upgrade... Tune your room and buy the BACCH filters...

And buy any amplifier you wish too if you can afford it... I cannot ... 😊

But if you do one thing , tune the room a bit...

 

 

The ego defends and fights.....that is its game.

Check out the GaN1 thread here on Audiogon for a couple of posts by people who liked the stock and modded GaN1 better than their $12K system. I did not make this up.

So, who do you know that liked their $500 class A/B better than the stock Gan1 by 70%? Do you have a link to their statements/postings? The stock GaN1 can only sound as good as the source and the digital cable and its footers, power cord, line conditioning, etc. Just the digital cable alone makes a world of difference....and of course, the mods take it to another whole level.

"Do you really want to hurt me?......do you really want to make me cry?"

Or.....do you really want to serve me....worship me......and want me to be happy?

You are beautiful, I am beautiful...everyone is beautiful....we are all worthy.  It is now time to stop this "making wrong" game.  Make everyone Right.....just say "YES!"  OMG it feels so good.
