Got a deal on an 80' roll of 14 AWG, black and orange, extension cable from home depot. Hacked off the ends, stripped, two conductors to ground, one to positive, works like a charm. I use bare ends with no bannas or spades, etc. I think the less layers of metal the signal has to pass through, the better. Sounds better than cheap wire, star-quad, and monster cable. I've never tried any of the high end stuff, but a buddy has some MIT's that I may borrow for a head to head.
