Forgive my ignorance on the matter of receivers, but could someone tell me if I could run a 5.1 speaker set up on a 6.1 reciever? I'm sure I could but would it be optimal to run a 5.1 on a 6.1 receiver like the Pioneer VSX-D912K? Would it be better to buy a 5.1 dedicated receiver to run a 5.1 speaker setup? I plan on buying the 5.1 Ascend Acoustics speakers and need to get a receiver for it. Any tips?
