From an engineering standpoint class AB is not that far off from class A (depicted on a load-line showing percent conduction at various bias points). However the alure of class A is undeniable. Esoteric's F03 (30w class A) is wonderful and fits in this discussion perfectly. My personal choice will always be an AB biased amp. I prefer my equipment left on 24/7 and class A amps simply run too hot.
