You may want to give Cardas Golden Reference a try. I use the bi-wire version with my N802's and Krell 350MC's. The sound is deep, extended, transparent and smooth. Speed, detail, and dynamic's are all there. They don't cost a small fortune either.
Best brand of cable for B&W N802?
I have been using Purist Audio Design Proteous rev B for 5 years now. I have recently purchased a pair of Transparent Ultra XL and compared them. I found the PAD to be more lively and realistic and the Ultra a little more like a reproduced sound. I am using a Krell AVS and 300S and I am curious if there is anyone that has tried NBS or PS Audio Lab Cables, etc. Please tell me how you selected your cable.
