Well Ive cut, chopped, soldered Ive used copper, copper with silver plating, various shark cables from maplins ranging from cheapo coax through to their pure silver variety and I have a clear winner by quite a margin; At the moment Ive not worked out which parts came from what so part numbers will follow but basically; I took a standard 70ohm coax which had a silver plated copper braided screen, stripped the copper conductor out of the centre, threaded 2 lengths of 0.380 99.999% silver down 2 channels NOT the centre were the original conductor was (so the wires dont touch) and used 2 qed phonos I had spare. The silver wires are soldered to the centre pin and the braid was soldered to the outer pin on the phono. I finished it with a braid sleeve and heatshrinked the phonos. At first I wasnt sure, it took a couple of days to come on song but now its great. I did some more listening between various cables last night and I was quite taken by how much better it is then anything else Ive tried. Give it a try.
