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


Cost ? Heat? Reliability?

The history of audio shows that you cannot make blanket assumptions on any product based on theory: There are too many variables to make any conclusion that class A is always sounds better than class AB. The results are aways dependent on the synergy between the amp, speakers, and room.
Basically you can say, all things being equal Class A sounds better, but all things are rarely equal are they?  I can't see myself owning anything other than a Class A triode wired tube amp but my setup is optimized for that style of amp.
