20 Year Old Amplifiers compared to 2017

The amp AB tests that I have read about...there is only a handful of them. They put people in unfamiliar rooms with unfamiliar gear and music...and of course it’s all too overwhelming to distinguish much. At audio shows you will sometimes hear people commenting that speakers start to sound the same. Anyway, we all have different hearing abilities. if someone can’t tell the difference between amps, it’s not accurate to assume that others can’t as well. 

Have recently tried a Nord class D amp and did not find it in the same league as class A amplifiers.
+1 on that, listened to many "good" ones now that owners say are good, but they still don't cut the mustard.

Bruno Putzey said in an interview earlier this year that if Class D sounds good, it sounds good despite the fact that it is Class D, not because it is Class D. Bruno basically said that efficiency is the only reason to molest a signal so dramatically. 

Dan D'Agostino, in his Stereophile interview, said, point blank, that some of his Krell offerings measured better than his current stuff. He specifically chose sound quality over measurements in his highly acclaimed breed of new Momentum components.

Chasing measurements will give you that clinical, dry, and lean sound. My guess is that its the sound signature of too much NFB. 

I imagine that Nelson underclocks the First Watt amps to prevent them from competing with Pass Labs.
