RE: Adiabatic pressure?

"The pressure distortion affects live sounds they (sic) same as reproduced sounds. So we hear that distortion either way."

I think the point is we don't hear that as distortion, just sound. Here's a hypothetical for you: what if there was an amplifier that mimicked the acoustic distortion of air? Would someone listening to that amp hear that as distortion? Answering that question calls for an imperial approach, with real people by listening.

Your approach, just build an amplifier without any distortion, strikes me as being somewhat intellectually lazy. By that I mean: you're ignoring the whole human ear/brain perception side of the equation. If I build a perfect amp with no distortion I won't have to worry about any of that messy biology stuff. It also strikes me as being arrogant, in the sense that it implies EEs know every possible type of distortion that can plague an amplifier and that they have the means available to measure it all. Even if someone could build your perfect amp with no discernible distortion, at the end of the day it would still come down to this: how does it sound playing music?
