For what it is worth, I tried many different manufacturers and different impedances from 90 to 110Ohm: Crystal Cable Micro and Reference, DH Labs (by the way these guys are the most helpful manufacturer I ever met), Sweetwater, Siltechs. Nothing worked over 3 meters without a transformer. Asked Audio Prana for theirs but they did not want to build a long one.
