Well, the walls are up in the new room and I've got a question running around my head - right now I've got "only" a 5.1 setup. So I'll clearly run the 2 surround wires throught the walls and out through a wall plate where the speakers will hang. However, in the future I'll be upgrading Next in line is my reciever but that'll probably be a little while. Do I run one line or two to the back wall? One for a rear center (DTS ES discrete) or two lines for rear surrounds (DD/THX EX)?? Personally I'm leaning towards two terminated into wall plates. Reasons are twofold, 1) 7.1 seems to be the latest thing and even if I went with a less expensive (than 7.1) 6.1 receiver I can always monoblock the other channel 2) speakers are bought in pairs as far as I know and (here is the big question) two speakers shouldn't affect DTS ES 6.1 - correct or no? Yikes, can anyone shed any light here?
