I apologize in advance for any terseness present in this posting, but for Heaven's sake, forget about CAT 5, 6 or 6000 for that matter! There are so many fine sounding, well constructed, reasonably priced speaker cables available that using "computer cable" designs is just silly. I have compared CAT cables to even modest audiophile offerings and there is no contest. If you look through Audiogon alone, you'll find many excellent offerings that will offer what CAT cables were neither intended nor designed to give you.
Spend wisely and enjoy the music!
