I would like to run a line from my sound card in my computer to my stereo receiver that is in another room. The wire will be ran through the walls and its length will be around 30ft. What kind of wire should I use to accomplish this and how much $$ would it run me? If its too much I could live without it - just an idea I had. A single wire would be easier to snake through the walls than two. By single I mean the insullation would be single holding two wires. Thanks for any suggestions.
