In Reply to: RE: Impressions of class D amps from Gilmore and Merrill... posted by mkuller on November 02, 2015 at 20:45:38
I've never heard better, no hardness, just plain muzic. If I had to guess I'd say it was a bad match with your speakers.

I would also think A/C supply, they are sensitive to this very much , but have to admit , i was experiencing the same with most class-D's I have tried before , never had the Merrill thou, the demo i had arranged fell thru and IMO, the Devialet's are the best of the rest so far...
With the exception of the Devialets, I would suggest that liking class-D sound (if such a thing) is music and taste dependent more so than Speakers. If electronic studio, modern Jazz and the sort is what you listen to mostly I can see class-D working for most , Classical , acoustic instruments and or anything with Piano's , I believe you will not like the sound of most Class-D amplifiers.

is an addiction to the artificial "bloom" of tubes...Those with tube systems often aren't accustom to the purity to the source provided by ncore and other ultra low distortion class d amps and characterize the sound as "sterile" or "colorless". Another common issue is that the ultra revealing nature of ncore causes the sound of upstream components to stand out, oftentimes it is the contribution of these components that is falsely attributed to the amp.
try it! you know you want to!
I like both my tube and solid state equipment and usually for different reasons. I think it easier to get good sound from tubes for lower dollars than S.S.
I have heard many class D amps and they never fail to disappoint. Not a question of distortion or bloom rather an issue of correct versus broken.

Perhaps broken was a bit harsh. How about a presentation completely lacking in anything even remotely organic sounding. Without fail class D has never left the surface of the speakers and seems painfully lacking in any aspect of sophistication.

I don't think it's a tubes vs Class D debate. It's a Class D vs "the others", at least in my case as I have had some excellent long-term solid-state amps.
So far, Class D amps that I have tried have lasted only a short while in my system but I admit that I haven't tried the mega-buck Class D amps in the $9K - $12K plus range.
Very interesting set of articles on his blog and in Positive Feedback on the SPEC class D amps from Japan. Designed with boutique caps and an original Class D approach, the amps are designed to sound like 300b single ended triode amps. I heard on and it definitely didn't sound like any other Class D I've heard. It's expensive and I'm not sure if it's for me but I would like to hear it again.
Thanks

using extremely high (80 db) amounts of corrective feedback (yeah, they're innately horribly nonlinear) to sound like those which employ none?
Somehow, TACT supposedly didn't use any negative feedback on the output of their Millenium amplifier. I would like to hear one again someday but my memory was that it sounded acceptable perhaps as a "summer" amp.
as opposed to analog switchers?
Yes, they directly convert PCM to PWM. Don't know why this can do without negative feedback but apparently it is different enough to allow it.
they're not really amplifiers in the traditional sense. They are high powered DACs. :)
...live music never sounds that "clinical" - with instruments and vocals in 2 dimensions isolated cleanly in space.
Regardless of measurements, music passing through either solid state devices or tubes gains a certain character.
Essentially, solid state devices emphasize transient attacks where tubes provide a longer decay.
Some prefer the sound of one over the other but neither is 100% accurate to the input.
I'm not going to reignite the tubes vs. solid state argument. But what you are confusing with sterile is not why those of us who like tubes - use them.
Sterile is that sense, or lack of sense, of nuance to tonal texture in background instruments. A lack of deepness to music.
A bad tube amp can sound just as sterile as a bad solid state amp. And a good solid state amp can sound just as good as a tube amp.
An good "stereo setup" is a good "stereo setup". regardless of what type it is.
