Thanks all. With all the hype, snake oil, and marketing attempts it's tough to know what to make of it all when dealing with cables (speakers, filters, anmps..this could go on forever) I have all Accoustic Research cables in all my stuff, but now that I think of it, I never did get the specific cables that they market for each piece of equipment. I just got on Ebay last year and found the lenght that I needed and order a bunch. Yes, it is an RCA to an RCA connection for the sub too.
