This is something of an odd set-up, so bear with me.

I have a Soundblaster Audigy2 ZS Platinum Pro sound card. I'd like to route my living audio through it instead of a receiver (which I don't currently own). My computer is in a bedroom adjacent to the living room and the TV is unfortunately not on the other side of that wall (that would be too easy) -- it's clear on the other side of the living room.

This is a small apartment with no room in the living room for a computer. I estimate I need about 30 feet of cable.

Is this possible, and if so, where do I find such a cable? All I can find is 3', 6', and 12' lengths. Are there signal repeaters that I can buy to achieve this? Would this have an adverse effect on quality?

Yes, there are signal repeaters. It is hard to find info on maximum length. (without an amp) I believe the recommendation for the technology is 35' max.

Armored?

Ah looks great, you guys are awesome. Are there any advantages/disadvantages to one long cable vs. a couple shorter ones with a repeater, you think?

My gut feeling is that repeaters might degrade the signal

Can you explain this? I'm new to this kind of stuff.

edit: Okay, I see what it is. Basically you're getting two cables stuck together, at a discounted rate. That's an interesting feature.
