Class D amps seem poised to take over. Then what?


I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

It has been said many many times. The Class of the amplifier is just one of the aspects of its design. Things like power supplies, quality of components, EMC measures, layout of the board, internal structure, internal cabling, etc all matter.

I have been using Class D amplifiers from the early days when some of them he emitted too much energy in the tweeters and could blow them up. The latest Hypex/Purifi/Icepower modules have improved tremendously but that is not to say that you can make a blanket statement that Class D is better than others.
My class A sugden A21se @ only 30 watts into 8 ohms/ 40 into 4 ohms sounds fantastic to my ears....simply pure, warm, effortless, detailed, full bodied, and natural sound. It has a nice wallop when needed...class D sounds much too dry to my ears...class A has a nice wet sound which I prefer. Sugden solid state class A, still going strong since 1967.

I especially enjoyed this paragraph, both for pointing out a psychological cause of instant resistance to Class D, as well as the variety of stakes in the way of trying something new.

And I don't hear you arguing against a variety of sounds -- just the exhortation to try new things before drawing conclusions.

This is the key sentence for me, and I'll quote the context below.

The only way I have found to re-anchor is through new experiences; technical and anecdotal evidence often is not enough. Without a new experience, how does one find the impetus to shift their perception fundamentally?"

"Anchoring can be a problem for audiophiles. Case in point: despite class D amplifiers being invented in the 1950s and having undergone extensive improvement by audiophile interests, such as ICEpower, for more than 20 years, it is still seen by many as a studio technology, designed to cut corners and save space and weight, a cheaper alternative, harsh and “digital” sounding, and not ready for prime time. It’s time you weighed anchor, because you are dragging. The term “anchors aweigh” means the anchors are cleared and the ship is ready for sailing. As of January 2021, these caveats are no longer applicable, at least to certain class D amps.

I attempt to actively resist anchoring to old perceptions about audio systems, as I do not find it to be advantageous, at least not in terms of pursuing the best sound. There are influencers, such as industry members with vested interests, who do not want the paradigm to change, as it could be damaging to their business. There are audiophiles who do not want the paradigm to change because it would adversely affect the resale value of their amplifier. There are some who anchored to an experience of hearing a class D amp from five or more years ago. The only way I have found to re-anchor is through new experiences; technical and anecdotal evidence often is not enough. Without a new experience, how does one find the impetus to shift their perception fundamentally?"


How many who've commented negatively on Class D have heard the Technics SU-G700 in their system?
Have you? @nonoise .

The way you are ranting about the Technics SU-G700 you are sounding a lot like a guy that many belittle for his passion for a specific brand in this forum.
