I'm now trying out a 3 meter Pangea AC9 which is replacing a Volex that I terminated myself. I've had it on for about a week on a Sim Audio amp that I leave on most of the time. So far it's a disappointment in that it has tipped the audio up to the treble and I have lost the slam at the bottom. It does some nice things with the high end and imaging. But that doesn't compensate for the loss at the bottom. Kind of surprising for a thick cord. Could it be those fixed terminations? Do you think more break-in will help? Or am I wasting my time?
