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. Present in every electro-mechanical-acoustical transducer ever built, yet infrequently does one find information (let alone useful information) that describe the type and degree of ...

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 ...

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 ...
