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

Bill

Ngjockey, you have to realize that linear power supply is in reality a primitive switcher that pollutes AC even more. Jeff Rowland designed his latest class AB power amps with SMPS to reduce noise.
this statement was a surprise to me.
can you explain why a linear power supply pollutes more than a SMPS? if it's true, it's certainly contrary to logic....
thanks.
