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.

True class A in my opinion benefits heavily from true balanced circuitry as well. Single ended is fine, but most amps will perform better all out XLR, even A-B.

Class A is a little weaker in wattage 9 times out of 10 and with an extra 6 db of gain from a balanced connection it does perform much better.

Plinius has a balanced connection so if you can do it go full balanced and really hear benefits regardless if its A or A-B.
