Just wondering again if this was possible. I haven't hooked them up yet, but I have a pair of TSi300's to be used as the front channel of a 5.1 surround with a DENON AVR 591 as the source. I believe that the 300's have provisions for bi-amping, but is it possible if I hooked up this system to run at 5.1 on the 'a' side for movies and such, and then be able to switch over to the 'b' side to just play cd's on the 300's? Can this be done without having to switch wiring? Not sure if I explained this correctly, but look forward to the feedback. Thanks.
