Well, I'm still trying to decide on a processor and poweramp combo but I think I need to decide first whether I'm going to be running a 5.1 or 7.1 setup as that affects the final decision. I've attached a floorplan of the room - Dynaudio Contour 1.3MkII up front with an Audience 122C Centre and Audience 52 rears and REL Strata III sub. The sofa position is non-negotiable (already managed to get agreement to rip out the old fireplace), and apart from a radiator and the stands for the rear speakers the sofa is pretty much against the rear wall. The question is, will it be possible to get an additional two rear speakers into the room to improve the rear sound, or am I better off sticking with the existing pair of rears? I guess I'm thinking of either a pair of the Audience 42W wall mount speakers equally spaced between the 52s or possibly a couple of ceiling speakers, but these would end up directly above the listening position, and pointing directly downwards. So, anyone else played around with rear speakers a lot?
