Overview

OFC copper power cable, 14 AWG / 3-conductor, NEMA 5-15 (US household) to IEC C13 (component end). Cryo-treated copper conductors, woven cotton dielectric inside a multi-layer shielded jacket. 1.8 m standard length.

Audibly useful gains over a stock molded power cable usually come from the shielding rather than the conductor — reducing the RF pollution that the AC line dumps into a sensitive analog stage. Modest expectations are appropriate: a power-cable upgrade is the last 1% of system optimization, not the first.

For maximum benefit pair with a power conditioner on the wall side.
