Silver / heat shrink braided RCA cables with Copper drain
|
A few years back I made some pure silver braided RCA cables where the third wire is not terminated at the destination end . The silver is polished then covered in heat shrink. There are two earth or negative wires. Theory is the third wire drains noise back to the source. In this build all those principals are used except the second earth wire is .8mm enameled copper wire. Smaller ferrite chokes were also used. I made these yellow to distinguish them from others. These are only 400mm long for phono preamp to preamp interconnect. Gold plugs and silver solder were used. Sound good.
