So you have a dealer (BJ Cables) who knows it all and denigrates others who feel otherwise based on their own experience. Not the objective type, I’d wager. Gotta love the know-it-alls.
Unless jaybe is an electrical engineer, or has experiencing manufacturing cable, it's rather likely the the owner of BJ cables does know more than jaybe about cables.
But such details don't seem to matter when it comes to audiophiles who hold their own perception as inviolable and indisputable.
