I'm not sure I've seen a class D amplifier which was 'voiced' in the audiophile foo foo sense. Class A/B lends itself more to the voicing voodoo. Class A amps are always 'voiced'.The only thing I notice on Amir's amp reviews is that some of the cheaper Class D amps become load dependent and the FR does change quite a bit based on the speaker load. This is not "on purpose voicing" but rather "save money on output filtering". https://www.audiosciencereview.com/...azon-basics-80-watt-class-d-amp-review.20943/
Not unless you believe manufacturer specs... many of which have been proven to be unreliable, lacking information or downright false.Is there any way to tell which amp is 'good' without measurement?
Well, yes. For this claim you'd have to do some reliable testing. But I'm perfectly fine with not yanking on that rope all over again. So, just for the casual chat, if you'd ask where would I put my money, it would probably be Rotel. If those two amps do sound different I'd be inclined to look for the difference in Rotel just because of the reputation of those companies boasting with "British sound". Once again, it's a guess.On a side note, I have the A-301 and they do not sound them same as my Rotels and DA-9. Now the big question is which one is neutral or which ones arent? I know this will boil down to someone asking me to do a blind test while volume matching all of them but its just not the same.
Yes, these days it's hardly ever in the very amplifying section itself. It's usually shaping the signal in the input or output stages.Aside from tube amps, I can't think of a way to design an amplifier without it being 'neutral' within its operating limits, if good design practice has been followed. Sure, its possible to design what are essentially 'effects boxes' but I don't consider them serious high fidelity amplifiers.
