there is a lot of misconception about 'pure class A'.
there are not much pure class A amps around. the old Pass Alephs were pure class A and they had not many watts.
most (almost all) amps are class AB.
it is all about bias. as an example if an amp has 600 watts into 8 ohm and the manufacturer claims 'pure class A' this amp should draw about 4 times 600 watt out of the wall. not very likely.
many tube amps manufaturers claim pure class A too.
you only have to look at the continuent current draw, ie if a tube amp draws say 400 watt continuely it will have about 100 watts pure class A. this is not an exact math figure.
i see another statement like 'this amp has big watts so it does bass well'. most of times this will work out, but i have experienced 50 watters which can put ashame any 1200 watter. watts never claim bass alone on amount of watts. its all in the powersupply..
Nelson Pass has a great article concerning pure class A at his website. check it out.
one of the heavy class A contenders are indeed the big Gryphons. boy they get HOT.
