These are absolutely outstanding IC's and a favorite of mine. It's with regret that I've decided to sell these. I've become a huge fan of silver IC's and love their qualities, when designed and made correctly. These Granite Audio cables easily fall into that category. Anyway, below are the details and a picture of them.
22-gauge, 99.9999% pure silver, Slow-Drawn Pure Silver (SDPS), continuous-cast crystal formation, 100% optimized shielding with both continuous foil and silver braid. RCAs: hard-gold over silver, over copper (WBT-0101 Topline RCA).

Thanks,
Mike
