Class A vs. AB vs. D... can you hear a difference?

All things remaining constant is there an audible difference?

I do not mean tube vs. Solid state.

All solid state.

Some Class A amps go to class AB after so many watts... is there an audible change?

I ask because I have a class AB amp and was thinking about going to a class D set up front for home theater

Thanks

Still not convinced with the high frequencies of any class D I've heard, but I've only heard a handful. Could say the same about most tube amps I've heard. Still have concerns about AC pollution of SMPS but that has become universal.

Having a pair of Plinius that can switch from AB to A, which is close to "all other things being equal", I prefer A. However, I could easily live with AB if I didn't have the choice and be joyfully ignorant of the subtle difference.
More to discover
