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


Cost ? Heat? Reliability?

Class A runs very hot and very inefficient , big watts in pure class A is big bucks

And when one's listening room is located in say Here in New Orleans, or Phoenix, or  South Florida, , the heat factor of a  class A amplifier is a  important consideration.
 The  Defy7 is like, I think Richard Gray says more like class B,  throws off  less that I had anticipated/with 12 tubes. 
, Richard also prefers Class A.
 But as you mention, Big Bucks. 
Did you say very inefficient?
Oh I see , requires plenty of power current = heat.
Glad the Defy is not class A. the heat  radiation would be too much to deal with in my 10x12 listening room.
