I'd like to run a stereo line from the output on my soundcard over to where my receiver is. In my equipment rack, I've got a 6-port Keystone plate , which already holds connects for satelleite, 2 subwoofer lines, phone, and ethernet. That leaves one blank space. I thought I'd just attach an eighth-inch chasis-mount stereo jack to a blank snap-in insert there, and tun a wire over to a similar plate in the office. What kind of wire to run though? Would a piece of Cat-5 do the trick, and just combine pairs, or should I run something different? FWIW, I'm only looking at about 15' of wire. Thanks for any help.
