I plan to listen to some B&W 802's in the near future. My current system uses 2 Parasound 1205's, with my main and center Klipschs passively bi-amped. Any thoughts on how these amps would mate with the B&W's? Would passively bi-amping them provide enough power to open up these speakers? I love my Parasounds, but are they of sufficient quality to do the B&W's justice?
