Conductors: Each conductor is made of oxygen-free 99.999% (5n) ultra-pure solid silver that has undergone deep cryogenic treatment. The silver wire used is manufactured by a company specializing in precision high-end audio and RF-specific silver wire technology. Polished to a completely burr-free, mirror-like finish to utilize the “skin effect” and to make the wire surface as smooth as possible for optimal electron flow… This wire is so professional.
