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.
