Go to Audio Asylum in the FAQ section and find Jon Risch's site. Read up on his DIY Belden 89259/89248 twisted pair. If you're handy they are a steal and very easy to make. If not then you can purchase them ready-made from several places, including Boldercables.com. These have bested many others that I have tried in my system (a DNA .5 near-revA)
Enjoy,
Bob
