I would second the Audience. Even their introductory level cable which no one talks much about at least the IC are called "Conductors" and are a great value. In general you should look for a small diameter conductor which is silver plated copper.
Back when Silver was cheaper, I had a custom silver ?alloy? power cable made for me, just for my sources. It worked out really well. A lot of times people want more fullness and rich warmth from cables, but I can see a source needing to be clean thus the custom silver cable I use. Sorry I don't remember which company it was but it was one of the commonly auctioned cable companys, that you used to see on Agon.
