More power does not hurt. I was a B&W dealer in the days of the original 801 and found they liked to be pushed. In those days B&W demoed them at shows with an ML 3 which had several hundred watts [and sounded like c**p ] and a Crown [SL 2, I think] which had a nominal 200 watt output but which could pulse 1800 watts at 2 ohms. I had one of the Crowns myself and they worked well. My experience in recent years has been limited to a pair of older 805s which I still have; but from what I have read they still like a lot of power. I would think something like the Musical Fidelity Kw 500 integrated, which has 500 watts at 8 ohms and more at lower impedance's would be ideal. The current 550 has even more power , I think. It would drive both pairs of 801s. I have the NuVista amp of theirs and am very happy with it.
