The comment about noise is a puzzler. "Noisy" in what way? I'm using a 460 watt per channel amp with 102 dB sensitive speakers and a tube preamp. If I stick my ear literally right next to the tweeter I can hear the faintest amount of hiss.
Time to buy a class D amp?
Will some new class D amplifiers outperforming the current ones appear soon
(the newest ones i know were released a few years ago)?
Class D amps attract me as I consider them the most ecological ones with obvious non-auditionable benefits.
I have no doubts that they posses the maximum ratio performance/sound quality among the amplifiers of all classes.
At the same time, the sound quality the class D amplifiers that I have auditioned produce, although is quite good,
but not yet ideal (for my taste).
I use PS Audio Stellar S300 amp with PS audio Gain Cell pre/DAC with Thiel CS 3.6 speakers in one of my systems.
The sound is ok (deep bass, clear soundstage) but not perfect (a bit bright and somehow dry, lacking warmness which might be more or less ok for rock but not for jazz music).
I wonder if there are softer sounding class D amps with the same or better details and resolution. Considering two reasonable (as to the budget) choices for test, Red Dragon S500 and Digital Audio Company's
Cherry 2 (or Maraschino monoblocks), did anybody compare these two?

Whenever I turn on my Class D amp, my dog goes running out of the That's the residual switching noise coming out of your tweeters freaking your dog out, because the output filter can,t get rid of it totally without effecting the audio band even more than it does with phase shift. If the switching frequency were higher then the filter can be higher, and filter out all of the switching noise without any phase shift down into the audio band. Technics does this with GaN Technology in their $$$$$$K SE-R1 Class-D power amp with a switching frequency at 1.5mhz instead of what everyone else uses at 600khz Cheers George |
Clearthink’s attitude towards, indifference to, or hate of, all things class D seems obvious. :-P It's pretty hard not to, when you know somethings not quite right in the upper-mids and highs, and then see this kind of phase shift going on in that same area https://ibb.co/48SSmLL . It’s enough to make clearthink think? Cheers George |
George. I own a class D integrated hybrid. I know from your past posts you are not a fan of class D. You say you hear somethings not quite right in the upper-mids and highs, and phase shift going on in those areas. Could you, respectfully, enlighten me as to what you are hearing? Please explain it to me, and I will try to understand what you are referring to. I have owned various amps over the years, mostly A/B types, and my class D amp easily outperformed all of them.
