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?

Does the Plinius 102 run hot in ab mode ?? --- I have a problem with a heater in the house during the summer months, and was hoping to be able to run it in ab mode and still get good sound.......
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.
