Class A amplifiers - which are considered the best

Rleff, The idea was an analog setup that used a feedforward system so that the bias is mapped in sync with the output signal. In effect there would be no 'decision point', merely a minimum level that represents no signal at all- as soon as you have some signal, the bias is increased or decreased in exact synchronization with the signal, so the amplifier is always operating in the class A region. However so far things have gone if favor of the KISS principle- So far the evidence suggests that such a system will produce some artifact.

Ralph, are the M60s pure class A? Not that I care, except theortically. I do remember when I bought my CAT JL2 that Ken Stevens scoffed at claims others made about being Class A (he had an SS design in mind), but I think his amp was pur Class A, it sure was hot enough, raising the room temp 5-7 degrees.

Reference Line Silver Signature from the late '90s. 100 watts into 8 ohms, doubles all the way down to 2 ohm loads. Designed for passive preamps and runs hot, so you have to be okay with those features. Top quality internal components. Built to last forever. Amazing transparency and ease.

The Audiopax Maggiore is a true 100W Class A amplifier so the "stretching the bow" comment does not apply in this case.

Yes James I believe these are class A most of the way, I know a friend of the designer here in Australia, Elson Silva, he builds "Cymer" amps here, he says there is just the same amount of fudging of class A amounts in the tube circles as well as solid state.
