@lalitk Right now I have narrowed it down to two cables.
1. Audio Envy O’nestian for $1250. They are using OCC copper and the cables appear to be very well constructed. Maybe the best I have seen at this price.
2. Gotham Audio XLR Cable, GAC-2 Ultra Pro, 10561 for $380. this cable ships from Germany and uses LCOF Copper, which is in between CFC and OCC. If you believe that single crystal copper actually improves the sound, then you pay the extra $800. The jury is still out on that one.
The Gotham cable appears to be just as well constructed as the Audio Envy. The difference is really the copper.
