I too am a proud owner of Krell components? I suggest you try Pure Note cables www.purenote.com. They are an excellent match for Krell and B&W speakers (I own ML speakers). These cables are very liquid, not at all like many silver cables. Perhaps they will have the tonal balance you are looking for.
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.
