Hi @total111, Mapleshade is a twisted wire referred to as the Clearview Double Helix.
It is this Wire that sparked an Interest in the Thread shown in the Links.

There is plenty going on within the Linked Thread to convince an individual expressing an interest in Speaker Cables, Umbilical Cable in the Signal Path or Power Cables, that a little experimentation can hit the right configuration for their purposes.
I have been in a uncertain situation with my audio equipment, as a Home Overhaul is to change things and when complete will be quite different to what I have created to date for a set up for my audio. This has stopped me doing certain things with Cable. I have a large reserve of PC Triple C Wire in Stranded and Solid, with a PC CCC / EX Wire also awaiting its usage. Again my system in late 2024 / early 2025 has been converted to Balanced, when I am once more settled the Wires will be used to produce Cables as outlined in the Links.
In the Links it is also able to found in the Original Thread, that I had encouraged a couple of individuals to use PC Triple C. On Page 16, it is possible to see the copy / pasted comments below, that area report by one builder with experience of other Wires used for same designs of Cable
" I like the Triple C XLRs very much. I believe they out perform my previous OCC builds. Just sensing more clarity, better voicing, overall info that I haven't heard previously with my go to music.
This is a 30" cable with AECO copper/silver XLRs. (2) 19awg bare Triple C conductors (+, -) inside teflon tubing. Neotech 16awg for ground (Helix wrap).
May look at replacing some internal hookup wire with the Triple C. Good stuff..."
In the UK there is commonly a reference made to using ZenMarket to get access to Vendors of the Wire.
