Hi JM,
I've tried a few cables in my MAC system. I've tried Kimber, Stealh, Nordost, Discovery, and a few others, but I've had the best results so far with Cardas Golden Reference. If I remember correctly Ron-C of MAC was/is a fan of Tributaries and Bigjoe certainyl knows MAC gear, so I would suggest taking advantage of this great community and try a few different cables. Since you're buying used to begin with, you won't lose much, if at all, on the resale if you don't like them.
