No. The sonic benefit is that the entire signal is swung by a transistor (or several in parallel) instead of individual halves of the signal being split up by two different transistors. Since there is no "handing off" of the signal to another transistor, there is potentially less distortion. But then feedback comes into play but that is another story...
Some will say that Class A always sounds better than Class A/B but in fact, it largely depends on the circuit design.
