Audio Research Ref 110 - Ref 3 Cable Interconect

I am using Kimber Select. All copper for a "warmer"sound, or you can move to hybrid (copper/silver) for more detail.
Either way the Kimber Select goes vey well with Audio Research. The Kimber Hero is "ok", but it's a limiting factor with components like the CD7 and Ref2 which I use.

I'm using ARC's balanced interconnects between my CD-7 and Ref-3 with excellent results. I recently replaced my old custom power cords, which were much better than the stock ARC cords, for Magnan ribbon power cords. The improvement in transparancy, expansion of sound stage and tonal balance is simply amazing. I would recommend Dave Magnan's ribbon power cords over all that I've heard. My next move will be to replace the ARC balanced interconnects for Magnan's 5i balanced ICs.

Nordost Valhallas connect my Ref3 to my Ref 110, and they work very well.
