Kimber Kable VS Speaker Cable

I moved my system around and now I have extra speaker cable. I was wondering would there be any benefit to double up my cables. They are 15 feet each, what if i cut them re-terminated them and wraped them with a covering so you dont see two sets of wires.

Would I hear a benefit?


Double run may sound even better than single one. If it doesn't contribute to the sound, I guess you can sell it in Audiogon.
Even better if you can do it in a shotgun bi-wire if your speakers can be bi-wired. Or bi-amp if you have the amps and your speakers can be bi-wired.
