I have been using a B&K av6000 for the fronts ( biamped) and an old pair of (don't laugh) Kenwood L05 mono block amps for the rear ( they are pretty decent amps to tell the truth I don't hear that much difference from the Kenwoods to the B&K) May change this setup once I get the 950 as I wont have enough channels to biamp any more if I go for 7 speaker setup
