@slaw I get it you’re looking for feedback from people who own or owned your amp. But one thing you have to realize that the same power cord on the same amp in two different systems in two different rooms will sound completely different. And on top of it, personal preference for specific type of sound will come into play.
So the feedback from owners is merely a guideline, nothing else. Might as well just welcome opinions from other experienced audiophiles who can recommend a nice power cable
Ignore the cotton ear ASR minions. Use everyone else’s feedback and filter it.
