I have a NAD C350 and B&W 602.5 S3s in my basement system, and have settled on Mapleshade Clearview Golden Helix, 85$. Get two pairs if you want to bi-wire, however I don't find that necessary. The Mapleshades are the clearest, most detailed, punchiest cable I have tried without being to bright or bloated. Mapleshade gives you 30 days to try them out.
