I bought the Discovery cable already assembled directly from Discovery, not as raw cable. I assume the skinny wire portion is the 32g wire sold by PCX but I don’t know for sure. As I said, that wire only extends a few inches past the tonearm base. At that point it is spliced to Discovery Plus 4 interconnect which goes on to the RCA plugs. What I bought was the complete cable with 18” or so of the skinny tonearm wire at one end already connected to the Plus 4 with RCA plugs at the other end. All I had to do was connect it to the Siggwan arm tube.
I should add that the tonearm wiring on the Siggwan is all on the outside of the arm tube. It fits into a groove on the underside of the arm tube. This makes swapping wires an easy task. Literally just a few minutes.
