Yup, those are them. A pair of Joe Mazzaglia's Auricle Audio Design, "Encore!" Kapton RCA interconnects.
"Other high end manufacturers use low-mass terminations in their designs, but the "Encore!" goes one step further, utilizing a 100% shielded, twisted-pair of mil-spec, 22ga silver/copper conductors in a kapton dielectric."
Corrections, their not a copper conductor but a twisted pair of 22ga silver/copper conductors.
NB
