@curiousjim Master Couplers are all over used sites, I’ve bought 5 or 6 of them from ebay or audiomart etc. SR doesn't make the anymore.
What was the first power cable that you noticed a difference in the sound?
I have bought six or seven different power cords, none over $500 and have noticed little or no change in the sound of my system. All the cables are 12 gauge or bigger. Without talking about cables made with unobtainium, where did you start hear a difference.
Thanks.
