As of yesterday, I now have 2 XLR cables (PS & PAD Dominus)plus the CAST interconnect. I will perform A/B testing once I get everything installed & report back. It may be a month or so before I feel that everything has settled in. The same goes for the 32X. Thanks for all your replies.
I still have the 32X DA from my previous system, but not sure that I'll hook it up to my new gear. My Mirage M1's and the Nakamichi (oldest gear)are also left over from my previous system. Thanks for everyones comments.
Actually, I just received the new gear recently, and am just finishing up the room prep work. The new lines are in, & today I'll start hanging the bass traps. Then I can unbox & connect the gear. The new speaker cables should arrive Friday, so............ Thanks for your replies.
