that's just nuts. Higher classes of operation reduce distortion ( and generate heat). While, as it goes from Class B through various shades of AB to A, you have a major league diminishing return - its always GOOD. Absolute utter nonsense.
I've designed more than i can count. I rarely go for pure A because its so inefficient and can be hot, but is always at least marginally better.
