Premium SuperTweeter Cables?

There’s a dearth of supertweeter cable offerings on the market. I don’t think Tannoy makes its "SuperLink" cables anymore - I had one and (unfortunately) sold it years ago. Looked like it was single-core solid silver, maybe 20 - 22 AWG in teflon.

What are good options, today - or whom would you commission to build a set? What would be the ideal AWG for a 16 kHz crossover point? I’m looking for premium options - I don’t want the $70 cheapie from AliExpress. I don’t like silver-plated copper. I prefer solid core high quality copper (preferably OCC) or silver. I don’t want a large-gauge firehose speaker cable dangling off these small tweeters. And cosmetics are also important - I don’t want it looking like something I put together myself. I should also note that I don’t care about or require Tannoy’s 3rd "earth" wire.

This is for Tannoy Canterbury GR and Prestige GR supertweeter. Required length is between 1.5 and 1.75 meters, for piggy-backing off the main speaker terminals. The main cable is Audioquest Wildwood (9 AWG, mix of solid core copper and silver wires). I’ve got a DIY pair of ST cables made from Neotech UP-OCC 20 AWG solid core hookup wire, which gets the job done - for now. I also have a spare pair of Audioquest KE-4 (15 AWG solid silver), but it’s a bit long at 8 feet, and 15 AWG seems like too much for this application. Should I look elsewhere, or stick with the cables I have?

I appreciate input from anyone with ST experience OR good ideas for a premium ~ 18 - 22 AWG cables. I’m NOT looking for comments on how this won’t make a difference, more than $20 is too much for a cable, you can’t hear supertweeters (you absolutely can) etc.
