A little debate between my friends, Dave, Tim, and I. Dave just bought the RX-V740, and a Cinema for the center. He is also using a pair of Aeon in the front, but they are driven by a B&K ref 2220, and is using a pair of Definitive Technology BP2X for the rears also. Now the arguement is Tim says the Yamaha isn't enough to power the Cinema center, but I believe since the mains are being powered by the B&K amp, and that the rears are fairly efficient speakers that it is fine. The center is also set to "small". Dave is now extremely concernd thinking he is going to ruin his new receiver, and as much as I try to reassure him he won't turn on his system until I have checked with you guy's. Anyway maybe I'm wrong, but I really don't think there is a problem here, but what do you guy's think? Anyone have a similar combo?
