Why would anyone want class AB amp when class A always sounds better ?


Cost ? Heat? Reliability?

Clas A amps DO NOT always sound better.
They should in theory perhaps but this ain’t theory now is it?
Provactive silly question.
Of course not what you mean.
Who cares whatever that is?
Yes, mapman, done right they do. 
Gryphon, Accuphase, Pass, Luxman etc.
"Some feel" funny things, that's for sure.
D'Agostino amps might be an exception in that they are top level and can compete with almost any SS.
