Has anyone made interconnects using Duelund 2.0 Silver Foil?

Years ago, I made a pair of 1/8 width silver foil interconnects, for my home built tube preamp and 300B PP tube amps. 4 Nines silver from Myron Toback in NYC, individually wrapped in Teflon tape, then wrapped together.  Sounds good, but I just broke one, so I am looking for for maybe something a little different.
How would the Duelund foil work out, either lightly twisted together, or placed in sheathing, or wrapped together in teflon tape.
Or is the Helix design a better option, could that be used with foil or is the round wire a better option.  Since the Duelund foil is so expensive, I am looking for more of a proven design.  I will be using the KLEI Absolute Harmony  RCA plugs.
Thanks,
Jeff from Brooklyn

@jcny111...
+1 for the Helix - but then I do have a little bit of a bias :-)

Seriously - give the Helix a try. A few members use them and love them

You might be able to use the silver foil as the signal conductor if you can insulate it.

But the UP-OCC solid silver wire is probably the best conductor on the market right now

Just focus on the last 2-3 pages

I'm using 2 x 18 gauge bare UP-OCC copper (Neotec) inside a teflon tube for the signal conductor and the results are stunning

@jcny111 - I used Mundorf Solid silver bare wire with 1% gold, But some prefer the VH Audio UP-OCC solid silver.

However - when I tried the UP-OCC solid copper from VH Audio it outperformed the Mundorf Silver/gold by a noticeable margin,
I then tried Neotech UP-OCC solid Copper and could not tell the difference, so I now use that in all my Cables and they sound stunning AND it is a lot more affordable.

I have tried the Neotec UP-OCC copper and and the VH Audio UP-OCC copper in IC’s and I could not tell the difference, but the heaviest VH Audio gauge is 18, so I use the Neotech.

I get the Neotec wire from HiFi collective because
  • they sell by the meter and I think it works out a little cheaper
  • their courier shipping is fast - 3 days normally
  • but, you might get a bill for duties - normally between $10-$20
  • if you select the postal service you do not pay the duties
The very latest IC’s use 2 x 18 gauge bare UP-OCC wires twisted together inside a larger teflon tube and that assembly has a cotton sleeve which is then placed inside the helix coil.

Hope that helps - Steve
