I have three dedicated lines with top end Furutech outlets on each one, and a Shunyata Cyclops v1. on my ARC REF 75 amp. Just for fun, I picked up an Entech niose detector, feeling fairly sure (perhaps a bit smugly) that I would find minimal issues. Was I ever surprised! Not only was there AC iine noise, I was also picking up a radio station on my dedicated lines. The Cyclops reduced the AC noise by 70% according to the Entech. The question is not do I have noise in my electrical circuit, but how much of a problem is it? I think I may see a Denali in my future...
