While class A has pluses the price you pay for it is high in less power and lots of heat, which is minimal at full power and greatest at least power, where the amp operates almost all the time. A watt is a fair amount of power, 85 db or more on most speakers, and that's pretty loud. Biasing class A at a watt or less does a pretty good job.

Let's say 1-5 watts which gets rid of the most blatant notch distortion. But a higher bias -- or pure class A -- gets rid of additional distortion according to various pundits.

  That's the conventional wisdom and it makes sense to me. But I recall an article somewhere where the writer claimed class B done correctly was better. And some of the greatest amps are probably David Berning's designs and his are as close to class B as he can make them.
