Getting back to the OP's original post. Class A circuits ( and we are specifically talking about amplifier output stages here ), just sound smoother, more homogenized, less artificial, more involving, with every attribute of recorded music reproduction, keeping one in his / her listening seat, longer. Granted, there are still audible differences, between designers and manufacturers products, but, Class A is still, imo, superior, at this particular time, in SQ.
