The cable is quad-shielded RG-6 with Stirling gold RCA crimp-on connectors, they were custom made to length by an audiophile friend of mine who had extra cable and connectors AND the tools to crimp them perfectly. Here's a link to similar connectors, it looks like the ones we used are discontinued. I was told these cables rival very expensive home audio interconnects but would reduce any noise along the cable since they are shielded so well. They were a pain to run and didn't bend easily, but I'm happy with them.
