I am seriously thinking of buying a receiver to go with my new panasonic lcd and pioneer bdp-320 player. I like the look of the pioneer vsx-919ah. i want to use it also with my nad cd player to take over from my tired cambridge audio A1 amp for music. Can anybody tell me if i have front, rear, centre speaker and a sub connected whether the receiver can be switched to play just two channels like a usual hifi amp would. cheers guys
