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