enbee23....... has sent me a fault cable the fault was easy to diagnose as the ground return had come adrift from the plug body. what was interesting was that as I scraped away the bad solder copper appeared the web site states "With The XXXXXXXXXX interconnect we start out with a high purity (99.99%) single, Teflon coated silver wire. Why silver? Because it’s a better conductor than copper. Why 99.99% purity? Because 5N silver (99.999% purity) is rare and on average costs 5-10 times more and very hard to produce and find. 6N silver (99.9999% purity) is too soft to produce, in other words it CANNOT be produced! Moreover, even if one could produce it, it would probably cost 100-500 times what 4N silver costs." This was a £250 ic Something is seriously amiss here ! the pic is not the greatest ever but the pink of the copper is clear, if you enlarge it ! I've contacted the makers but still waiting for a reply
