Just got a Rotel RMB-1075, it's currently mated up to a Marantz SR7300 but that will be replaced by a Rotel RSP-1066 in a few weeks. I'm currently using digital coax cables (AR Pro Series) as interconnects honestly because it's all I had on-hand when my 1066 got here. What I'm curious about is if this is a good choice or not given the wire core. They have a solid 99.97% pure, oxygen-free, copper center conductor wil 95% copper braids and 100% aluminum Mylar foil shielding. I compared these to a set of AR Pro Series stereo pair, they are almost the same but feature a twisted pair multistrand core instead of a solid one. Which is better to use for connecting my pre/pro to the unblanced amp input? Anyway, I'm looking for suggestions on some good interconnects for the unbalanced line in if my choices are poor. I'm fairly savvy with HT components but I never stopped to think about these interconnects. Thanks!
