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.

I owned the SA100MKIII and preferred class A over AB, it was really liquid and had better weight and a deeper soundstage, also more of an intimate and revealing inner glow quality.

not quite tubes but as close as I have heard from SS.

no contest in my book, on Maggie 1.6 btw...

Minorl,

you can flick a switch on the Plinius and change it between class A or class A/B, one amp offers both functions
