I appreciate the advice to try more expensive power cables in addition to cheaper ones, on a return and refund basis. So I will need to figure out which ones to try. Zafino seems to have a pretty heavy restocking fee, on a cheap cable its no biggie but if I am trying a $800-1000 cable as you guys suggest I don’t really want to pay $150 just for a trial if it isn’t an improvement.
Even doing it this way, if the cheaper cable didn’t improve things, and neither did the expensive one, well then the comeback is hey there you didn’t pick right expensive cable!!! So that’s why I am trying to poll the good folks here which brands they have really have good luck with. Seems like ones that may be worth trying are older Shunyata Venom or Synergistic Master Coupler, if I can pick em up used then just resell if they don’t sound better.
