After seeing this thread, and your post, I decided to make my own signal ground cable. I used some 16 gauge magnet wire I had around. Instead of making five separate wires, I combined them all into one. One spade on the Everest side, then I twisted it for about 4 feet. The last 3 ft is a single magnet wire to each negative pin on the rca/xlr connectors. This saved a lot of space on the ground post of the Everest, and is a little tidier.I have the Everest conditioner.
Made my own signal grounding cables from some spare AntiCable solid core speaker wire and these RCA connectors available on Ebay.
All my components are now signal grounded to the Everest grounding.
