This is a 4 foot pair of 17 ga. solid core .9999 soft annealed silver cables. The individual channels have separate cables, each with 2 20 ga. wires, effectively 17 ga. per leg, in a Teflex jacket.
I did not make them. The maker is reliable, imo.
32 feet of silver wire in teflon dielectric tubes. Use as-is or use it make ICs, hookup wire, etc. at a sizable discount.

The connectors are Furez pure copper spades.
Well made as DIY go, but 2 cables have a different heat shrink tubing on one end.
Very nice sounding, no silver "emphasis", just smooth detail. I actually used them as woofer cables in a biwire speaker, and they were very well balanced, detailed and clean.
The wire alone is ~$160 now. Add in the rest and ~$200 to build.
Thanks for having a look!
