I have received my XINHS cables today.
I ordered custom shorter length (60 cm) and explored different insulation materials - the only excuses I can pull to get yet more cables.
The price for all 3 cables were ~$60-63 (really great deal, the core materials are "single crystal copper", I was not looking for anything fancy there).
On the image above -
top white/clear is PU (polyurethane) -jacketed, 4-core single copper. It measures at below 0.2 Ohm for 6 cm, being equivalent to 0.3-0.4 Ohm for the standard 1.2-m length.
Bottom right - black TPE (thermoplastic elastomer) 8-core single copper; it measures 0.4-0.5 Ohm in full-length equivalent.
Bottom left is common PVC 24-core, loved the colour, perhaps a bit too vivid. While the thickestitas expected for the 24-core, it measures the highest at 0.5-0.6 Ohm in full-length equivalent, similar to typical 16 cores, since it is reasonable to assume that most of the thickness is insulation.
PU and TPE were the only options available.
In terms of smell, TPE has the least, next to none (likely residuals from being stored with other cables), as expected, since no plasticizers are needed; PU is not void of smell, different from PVC, less but strong and evident...
24-core PVC is not the most smelly that I had, but strong.
In terms of tactile feeling: TPE is rubbery (it is an elastomer after all), I like it and can recommend it as a non-smelly option for black cable lovers
PU did not strike me as any better than PVC. The conductivity of this thick 4-core is very good though.
I will now enjoy my wide- nozzle ASX more than ever (have not got any IEMs in 4 months); just Shanling UA2 is on the way, almost there
P. S. My highest recommendation for XINHS - amazing communication, perfect customization, great prices (no affiliation, paid fully what was asked).
P. P. S. The cable community can take the full credit for XINHS - the strong demand for custom cables made possible suxh great opportunities, I am really grateful for this, as a perhaps not "unconditional cable believer", but enjoying these cables as much as I can
