diy interconnect recipe?

Some Beldon wire, some decent RCA, WBT is Audio Jewlery(overkill) copper. Silver solder. Shrink wrap, and away you go.

I had pretty good success with 24 ga. high purity solid silver wire in individual Teflon tubes. I used 7 wires in a very loose braid - 3 for the signal, 4 for the return. These were terminated with copper Eichmann Bullet plugs (the silver ones were not available at the time) using decent solder, and I used no covering or shielding (OK for my area - maybe not for your's).

They are surprisingly robust, but take a little while to break in - I sped up the process with a Hagerman Fry Kleaner.

Regards,

If you decide to go with silver solder [not really necessary] make sure that it is for electronics and not for jewelry.

In lead/tin solder, rosin core makes the job a whole lot easier. You may also want to pick up some flux paste, which cleans the wire, and makes the soldier flow better, Be sure that the flux is rosin and NOT acid flux, which is used for plumbing, and not for electronics work.
