If I were a solid core silver rca interconnect cable fan vs. a solid core copper rca interconnect cable fan for line-level analog cable applications, I'm sure I would like to try cotton tubing as a dielectric.
While a balanced digital signal is a different animal than a balanced line-level signal, both require a twisted pair in order function properly with balanced I/O circuitry. As for cotton tubing being absolutely better than a very thin hand-built layer of PTFE Teflon tape, I prefer a minimal-mass, very thin PTFE Teflon tape layer approach for a tightly-twisted pair, and I doubt there would be a profound difference from an audible dielectric absorption POV. You may like to try VH Audio's AirLok insulated OCC copper wire to hear how good a minimal-mass cellular FEP Teflon dielectric can sound.
BTW, what make/model connector is your Paul Speltz cable(s) terminated with?
a digital cable. As to Speltz I was in on the ground floor. I had his first which was 2 pos cables with RCA pin onlt and one ground with a ring sleeve for one RCA ground as they are common.
I then got his copper with the curled return with Neutrik and then jumped to his best silver with silver Eichmanns

Partsconnection has Duelund 6N dead soft silver wire that has an oil impregated cotton jacket. Wouldn't that be something to try? With the cotton jacket in place twisting shouldn't present a problem.
I have fully explained in this thread as to why I don't consider a fluffy cotton, or even an oil impregnated cotton tubing without any air as part of the dielectric for that matter to be suitable for use as a precision twisted pair in order to build a proper home-brew AES/EBU digital cable, in my own personal opinion. Again, if I were interested in building a pure silver analog interconnect, or a pure silver speaker cable, cotton tubing would be on my short list of designs to consider, but not necessarily the only option to choose from. Anyone who has not experienced just how incredibly thin the typical white colored PTFE Teflon tape actually is, and the notion of only implementing a single run of PTFE Teflon tape with a half-overlap that effectively provides 2-layers of tape wrap for each wire, might like to spend a buck for a roll of it from a local hardware store to see how little dielectric mass, and thus dielectric absorption is involved in my intended design.
