Why do I like Class AB better than Class A?


So I just purchased a Plinius SA 100 MKIII, and have had 2 listening sessions comparing both with the toggle switch. To me clearly the AB is more detailed and focused, the A is warm but a little fuzzy and bloated, although I would give it a slight nod on just vocal songs. Am I just not use to the sound as this is my first A amp or have I not let it properly warm up for class A (1hour or so).
Don't get me wrong, i love the amp, great bottom end slam but I don't hear the holy grail from Class A. Thanks in advance for the input guys.

Ryder, great description of the Plinius, it is exactly how I feel it sounds between A and AB. If I may ask what did you move onto for amplification and why? Thanks in advance.
Hey guys, my source is MacMini running PureMusic, Wyred4Souns DAC 2, Aiff. I think I have solved the issue, I hadn't let her warm up enough, I thought 20 or so minutes was going to be sufficient but it was not, I give her 2 hours+ and is much much better. Though it still prefer AB with busy or complicated music like progressive metal and such. Thanks again
