The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown, 1 but they are not common.

There are two salient facts about Class A amplifiers: they are inefficient; they give the best possible distortion performance. The quiescent dissipation of the classic Class A amplifier is equal to ...

Distortion comes in a huge range of slightly different forms, from subtle analogue warmth to extreme metal fuzz, mild digital imprecision to eardrum-bursting clipping. But what is distortion, what's ...

Given all the foregoing research presented in various academic, scientific & industry journals, as well as other media, variously indicating the audibility of phase distortion, there remains no valid ...

There’s nothing quite like stepping on a pedal and hearing the gritty growl of heavy distortion. Deforming your guitar signal to the point that it screams back at you is incredibly satisfying so ...

Recently I've done a collection of measurements and tests on interconnect cables to see what I could find that would explain the sonic differences that many people, including myself, have grown ...
