Unfortunatelly, I can only confirm some previous comments. I bought 12 of them, 4 were used with Mogami 2549, 4 with Canare 4e6s, on both very poor results in higher tones. 4 will remain unused. Cables were made by devoted audiophile who owns workshop which is also authorised repair service for Bang and Olufsen, Bose, ... My worst 'audiophile' purchase so far. Sorry to write this I was really looking forward to them.
Higher tones are supressed, no joy in listening music through these connectors. I should have gone for Neutrik or Klei. Money lost. I will probably buy Klei.
