Zonotone Interconnect Cable 6NAC-Granster 3000a RCA Cable 1m Pair In my personal opinion, I've used other cables from Zonotone, QED, and Ortofon, but with cables of 6N purity or higher, it's difficult to tell the difference in a blind test. This is a wide-range, excellent cable. I'm selling it because I no longer need it due to equipment reorganization.
