"GPowered: which cables are you using?"
I am using JW Audio Reference Interconnects and speaker cable. They are cryo treated and cooked solid core copper. Hit Zman up if you want to demo. They are simply the best I have ever heard and not expensive. The Ref IC's are new and prob not on his website yet, but compared to the Signature (i used it for 5 mths or so prior), there is absolutely no glare or etch and they are natural as I have experienced. Soundstage is wide and deep - nothing left to be desired. So before you dish out a bunch of cash, I strongly recommend you give them a try. I never would have though these would have been what they are.
