Power Cable Upgrade a wide range of audio/video components, constant- and variable-current alike, with AudioQuest’s Blizzard 3-pole AC power cable. Blizzard features True Concentric Perfect-Surface Plus (PSC+) conductors that have been carefully controlled for directionality to efficiently drain RF noise. ZERO-Tech ensures uncompressed current transfer while RF/ND-Tech minimizes circuit misbehavior by cancelling induced RF noise for quiet backgrounds and thrilling dynamics. Blizzard adds AudioQuest’s patented 72v Dielectric-Bias System, which further reduces radio-frequency noise.
