Any review in 6Moons is suspect. The publisher is very open about his "pay to play" business model. Any company wanting a review has to pay for it. So reviews in 6Moons are just another form of paid advertising. I am not saying other webzines don't do this too but 6Moons is the only one I know of that admits this openly.
Gutwire Perfect Grounding Cable
The cable's single rca plug is connected to an unused input on my Pathos TT integrated and the AC connector is plugged into an unused wall socket. It isn't broken in yet, but there is an immediate improvement (reduction of the noise floor, etc.) consistent with the review.Haven't tried grounding boxes (e.g.,Entreq) because of their cost, but the Blue Moon award (Six Moons) winning Gutwire Perfect Ground cable at under $300 (see Gutwire's website) is worth trying.
