Covering silver wire for use as a speaker cable

If the wire is bare, pass it through polyurethane and let it dry & cure hanging overnight. Then snake each strand through a long 2mm cotton sleeve and make a loose litz braid of all strands. Soak a 1" band of ERS cloth in Goop cement and wrap around both ends. Remove urethane from ends with an exacto knife, twist and terminate wire bare.

Reference Audio Mods has it. Bend back the tip to make a tight curve with a smooth point and snake it through. If you want to send several strands together through a single sleeve, wrap the tips tightly in teflon tape. Be forewarned that jewelers silver may not sound as good as silver made specifically for audio.

2mm cotton sleeves from RAM for proper litz braid, or various sized rolls of polyolefin HS tube from McMaster Carr if you just want to bundle 10 or so strands together inside one tube.
