Go for the Siltech, no contest compared to Colussus. The PAD Dominus is an incredible cable, but the lower PADs aren't so hot, IMO of course. Plus, you already own Siltech speaker cables, and silver works VERY well with Pass electronics. I would recommend some SQ-88 G3 Siltechs and you'll be a happy camper. Not obscenely priced if you can find them used or from an internet dealer either...
