Everyone's talking about the cable, but for essentially the same cost you may be able to make something better than the CAT5 braid. Yes, it did sound better than stock 12 uage speaker wire, but it also had a bit of a smearing effect. This was not terribly noticeable to me until I heard it removed though, so YMMV.
I am talking about a pair I made by just braiding 3 CAT5 wires together. This smearing may be lessened if you take the cables apart and match up wire pairs with similar twist ratios. That is a lot of work though.
Jon's 89259 cross conencts have a much clearer presentation and no smearing of the treble. Imaging is more precise and defined than with the CAT5.
Good luck,
Bob
