Nirvana cables...anyone with experience?

I've got three pairs. They are hard to come by so i use them inconjunction with Cardas N Ref.

I evaluated Harmonic, Audioquest Anaconda, and Nirvana S-X ic in my system. Nirvana S-X rules. I am comparing the S-X to a similar priced Siltech 4FTM this week.

I compare the Nirvana S-X with Cardas Golden Reference and NBS Monitor I interconnect cables. I choose the NBS Monitor I over the Nirvana S-X and Golden Reference. With the NBS Monitor I, my system produce music that is so 3D with a spooky realism. S-X is close but the image is not as sharp and the background is not as quiet or black as the NBS Monitor I. The Cardas Golden Reference is a distant 3rd. By comparison, the Golden Reference is not as detailed and the image is fuzzy. Without comparison, I would propably like either the Golden Reference or the S-X. But after hearing what the NBS Monitor I can do for my system,I would not buy anything else. Give the NBS a try, you will understand what I am talking about. By the way my system consists of: Muse model 8 and 296, CAT Ultimate preamp, Krell FPB 300, PS Audio PP300, Synergistic Designer's Reference power cords.

Just an addendum to my post above I forgot to mention that the speakers that I use during my comparison audition are the B&W Nautilus 802.

The recent review in Stereophile describes the difference between the newer S-X and the lower priced S-L. I own both S-L interconnect and speaker cable and find it is among the most musical sounding cable I have heard. While the S-L may not be a 3-D sounding as XLO's best or some others, it produces a huge soundstage with greatly nuanced sound. Very appealing, warm sounding cable. Read the rave 'Phile review--it was right on.
