AudioQuest Blizzard Power Cable (20Amp) Delivers an Overabundance of Upgraded Performance: ZERO Characteristic and Ground-Noise Dissipation Accompany 72V Dielectric-Bias System What makes the AudioQuest Blizzard power cable special? In a few words, ZERO (No) Characteristic Impedance and patented Ground-Noise Dissipation technologies . The former enables uncompressed current transfer while the latter feature prevents noise-induced transient-intermodulation distortion. Then, add traditional AudioQuest elements such as a 72V Dielectric-Bias System and controlling metal directionality that drains radio-frequency noise. Built with Perfect-Surface+ copper , Blizzard also gets true concentric conductors in which the outer layer is spiraled in the opposite direction from the layer underneath, enhancing mechanical stability and decreasing stand-to-strand electrical contact. Indeed, the implementation of a single-stranded conductor per polarity allows Blizzard to fit in a single jacket and expand its flexibility even while maintaining a 20Amp at 120V rating. In every way, Blizzard will blow away the abilities your prior power cable and let you hear more music, detail, information, dynamics, tonality, and more. 100% Music Direct Guaranteed.
