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


Cost ? Heat? Reliability?

Obviously.

It's just too hard to keep the snark in, right?
Haven't we all had enough of such meanness?
Because Class A does not always sound better. Obviously.

They always do, but it has to be the same amp designed to take both settings low Class-A bias and high Class-A bias without being stressed.

EG:
Halo JC1’s always sound better in high class-a bias
Gryphon Antillion always sound better in the highest class-A bias
etc etc etc

The more and more class-A bias the less xover distortion there is and so on the louder you go, on and on till the amp reaches clipping when the amp is in full class-A never switching off either complimentary side of the push pull transistors. Then there's single ended class-A tube and SS but they have to be either capacitor or transformer coupled, not my cup of tea.

Audiophiles love some things.
If distortioin is kept low, no audible difference.
Today you can have really good sounding amps in A, AB or D designs.
So preference rules here.
