@dtximages, which Furman do you have? I just upgraded to a Furman Elite 15 PFi with solid results. It replaced an old Belkin PureAV PF-60. I now have Audience Forte F3 PowerChords on all components in my system, including the Furman. Like you, I also have the M700 and SGCD stack.
I have the same one. My problem is that my situation makes it VERY hard to actually A/B test anything. I THINK it sounds better haha but I also believe in confirmation bias and 5 mins of listening changes your hearing and you think you hear things you don’t etc.
Yeah then Paul, in one of his videos I believe, mentioned that often Power Conditioners make sound worse by “bleaching” it. Might have a darker background, but, at the expense of sucking away life. I’m not sure how this is possible and I do rely too much on others’ opinions who are able to better listen, test, judge.
