audioseeker, I would suggest the Cordmate or Cordmate II paintable on-wall raceways, available at the Home Depot and other home improvement warehouses. The raceways will be still visible on the wall, but they make it look much neater. Of course, in this case you don’t have to worry about the “looks” of the wires themselves.

And, since you gave me another chance to show off the picture of our living-room HT , here is an example using the Cordmate II raceways.
