I just heard the belles mono blocks the other day and they were incredible. Speakers were german physiks carbon MkIV's and 3A reference top of the line. Not quite enough power for the physiks for me but they were stunning with the 3A's. also paired with the belles pre amp. As good as any mono's I've heard. Same dealer also had the vitus mono's which were also incredibly good.
