Why are you wanting to BiAmp? Are you wanting to BiAmp all three speakers? Will you have a powered subwoofer? To BiAmp the front speakers will require six channels of amplification. I'm a little baffled. I have a 5.1 system and no biamping. 200 watts per channel at 8 ohms and its as good as most digital movie theaters. Adaptive di-poles in the rear.
