how is this supposed to work?
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.
