RF-Dissipating Ground Wire Unlike other ground wires that act as radio-frequency antennas, AudioQuest Black Hole GroundGoody prevents hum while efficiently dissipating radio-frequency noise. AudioQuest Black Hole GroundGoody uses premium conductor materials — AudioQuest’s 6% Silver over Long-Grain Copper — that are controlled for direction and cold-welded to Direct-Silver Plated #10 size spade lugs. Further, AudioQuest Black Hole GroundGoody employs a Carbon RF-Trap comprising conductive PVC to aid RF-noise dissipation.
