Hi Simancd,
I have a similar setup as you for home theater. What kind of speakers do you have? This would help in the decision of which interconnect to use. Also.. what is your source?
After testing A BUNCH of interconnects (you name it, I've tested it), I decided that Audioquest Diamond X3's were the best for my situation & preference. They are simply fantastic. Even though they are silver, they don't have the stereotypical "brightness" people commonly (and wrongly) associate to silver. I've found that silver really helps preserve the delicate signal between source components and pre-amps/amps. I've used these cables on VTL tube gear as well with similar results. Great cables!
and great cables are great, no matter how they are used.
