I made the cables for front and center about 3 years ago. As one of the above posters mentioned it was very time consuming and rough on the fingers (i had blisters for a week!!)

Did they sound better? Yes, of course I was replacing cheap lamp cord.

Would I do it again? No, as a matter of fact I recently replaced them when I upgraded my system (950/770, Rocket Speakers).

I found some very reasonable cable from a company called Canare, which was originally intended for microphones (i think??) Anyway, a couple of other groups I read swore by it. I have been very pleased as well.
