It may be true, especially with earplugs that we cannot hear the difference between class A amps and the newer technologies. But why do people still pay a huge premium for class A amps?

I will not be surprised; so many advances have taken place since tubes went out of favor.
The distortion figures that manufacturers give will be wrong in final output - they never ever perform that well. What will happen is that those numbers will be about 100-1000x more noisy, but still be beautiful.
I don’t know about the numbers, I think that is what MacIntosh use to check for at there clinics. I do think that if any amp is actually going to improve the sound class A, should have a good crack at it.
The part may actually perform that well, but when used with everything else, will pick up lots of noise. Never look at one part only - it will only frumple the plans.
Maybe someone will figure this out and I can read the report. In theory, class A should have advantages. Thanks for taking the time to explain.
