question to Plinius Amp owner

Just curious to know what is the sounding difference you experience when you switch between class A and class AB? I guess this comparison might be more objective since the rest of circuit is the same except the bias. Can you confortably draw the conclusion that class a mode is better in every aspect ?
Thanks!

to my ears, the plinius in class a, is absolutely wonderful. perhaps close to the best characteristics of both tubes and solid state, but then, i may be a bit biased.

Lak & Danderson,
I'm not questioning your opinions but just a little bit confused. If what you said are ture, then it makes me wonders why Plinius bother to add a AB mode switch there ?

Easy, AB mode = less heat and less electrical comsuption, AB mode is fine for casual listenings, for example.

I usually listen to AB also however if I'm doing critical listening I always use A.

AB= cool to the touch.
A= hot to the touch.
There also seems to be more PRAT associated with A.
