Hi,> I, for one, can hear less noise. And there are 5 reviews of this
> unit that supports my view.If you cannot hear the noise at all (because it is so low that it is inaudible) how can you hear even less noise?
Again, you may be mistaking other effects.
What you would need to do, in effect, is to find a way to add the noise of your old amp's back to the new Amp so you can switch the addition on and off and see if you actually can hear the difference.
I would also note that specific amp under debate has comparably low gain (which in my view is a good idea BTW) and so in a complete system with a preamp would quite substantially lower system-wide noise.
FWIW, I am using a Tube Amp with around 96dB SNR at 2.83V (measured on AP2) and speakers with 90dB/2.83V sensitivity. The Amp also has intentionally fairly low gain and a similar spectrum but much lower levels of HD than the speakers have at 2.83V input. The DAC that drives this Amplifier has 114dB(A) SNR. And yup, this DAC's is also inaudible with the volume set to max.
Even sticking my ear into the speakers I hear no noise whatsoever, no hum, no hiss, nothing. Lowering the noise of this amp would pointless, unless I switch to much higher sensitivity speakers. The HD is also while not very low, lower than most speakers I have ever come across at 90dB SPL and thus also inaudible.
But I am sure if I switched it for a 112dB SNR @ 2.83V Amplifier that is all transistor I would hear a difference. Yet I believe you would agree that it would be foolish to suggest that the difference I would be hearing would be explained by the 16dB difference in SNR (or the difference in HD FWIW), given that no noise is audible regardless which amplifier is in use.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
