one last note, the way its working out i have no choice but to run all the wire through the same pipe. all wires being, the plasma power cord, hdmi cable, and my center channel speaker wire. do you think there will be a noticeable sound quality difference for my center channel? should i buy shieled speaker wire for this run? would that help? right now i'm using 12 gauge aperion speaker wire. what do you guys think? like always i appreciate your expertise.
