I have got one, what do you want to know?
In my system, it has authority at loud and soft volume but it can play very loud (for 100 watts), has excellent control of the bass drivers, the treble is extended, sounds a tad warm (but I have a tube preamp). I would recommend checking it out without hesitation. It does get hot, even at low power. I compared it to Krell and Classe. I thought it was better for my system. The problem with BAT is you might have trouble getting a good price.
I have a CD connected to a Proceed DAP, SF Line 2, Vandersteen 2ce and can run the whole sheband balanced.
