I will agree with Ryder on that one. I have frequently heard a Plinius SA250 MKIV and although the SA100 is not in the same league, there is a definite Plinius housesound.
But in my sense, and my preferences, choice of gear is highly dependable of type of music preferences. Soft jazz, feminine voices and small orchestra music will come out beautifully on class A amps because of their general richness in tonality. Music that produce fast transients and dynamic contrast will generally be better on faster amps and in this sense, class A and probably tube amps will fall second to an AB of good quality.
