Here is a quick and easy DIY project for the audio enthusiast...
Custom silver SE interconnects
**Supplies:**
[LIST=1]
[*]4x Quality RCA Plugs (Neutrik, WTB, Furutech)
[*]5 meter drawn silver wire (from your local gold smith)
[*]2 meter teflon tube with an OD of ~2 mm
[*]2 meter teflon tube with an OD of ~6 mm
[*]5 meter Megamide/Nylon braided sleeve with an OD of ~8 mm
[*]1 meter heat shrinkable tube with an OD of ~8 mm
[*]Silver solder
[*]Necessary tools (soldering iron, side-cutters, heat gun, etc)
[/LIST]
**Procedure:**
[LIST=1]
[*]Cut two pieces of silver wire of 1 meter as well as two pieces of teflon tubing. Thread wire through teflon tubing.
[*]Divide the remaining 3 meter silver wire in two lengths of 1.5 meter each. Take a piece and wrap it around the first tube with the straight piece of silver wire. Spread the spiral evenly along the length of the inner teflon tube.
[*]Thread the assembly through the ~6 mm teflon tubing (which should be cut to 1 meter lengths each). It will be tricky but a steady hand a patients would do it.
[*]Cut four pieces of 250 mm heatshink tube.
[*]Using a hot soldering iron cut two pieces of 1 meter nylon braid sleeve. Thread the "cable construction" through the braid sleeve.
[*]Slip two pieces of 250 mm heatshrink over each cable assembly.
[*]Solder straight conductor to RCA center pin and spiral conductor to the ground point. Remember to slip over the RCA barrel overs it the attach from the rear of the assembly.
[*]Slip the heatshrink over the assembly inside the RCA unit with some protruding at the rear and secure with heat (using a heat gun)
[*]Close up the RCAs with the supplied barrels and enjoy your new DIY silver cable!

The spiral assembly can be substituted for a conventional "twisted pair configuration".
