I just purchased a samsung plasma and i need a new receiver. I looked at the Panasonic SA-XR57 and I need some reviews about it. I need to hookup a Samsung upconvert dvd player, Direct Tv receiver, and Xbox 360. The size of the room is 11x11 and right now I have an old Sony THIB and now I want something that sounds clearer and better. Im going to purchase the Athena C1.2 center speaker and i need suggestions for the surround and subwoofer. Thanks in advance
