Plinius class A vs. class AB sound difference?

I am considering purchasing a Plinius amp. I have read that many audiophiles do not hear a difference in an SA100 when it is switched between class A and Class AB modes of operation. If this is indeed the case, then would a Plinius 8200p (power amp; not the integrated) which is supposedly the same class AB circuitry found in the SA100, sound identical to the SA100?

My SA100 MKIII has just the slightest amount of grain in AB mode that is gone in A mode, also in class A there seems to be better definition, or maybe it is my imagination, it is that close. It sounds superb in both modes (driving Maggie 1.6s).

To elaborate on my response - I agree with Jayctoy's description, after reading this post I listened to my amp in class ab for a few nights and was less involved in the experience than in class a. It is nice to be back to class a, it is more liquid and pure. In class a the music has a nice 'inner glow'. This is fine amplifier.

I guess switching back and forth between the two tells you very little, I agree it must take a while for the change to occur.
