AudioQuest NRG Edison

AudioQuest NRG Edison (15 AMP) POLISHED HIGH-TENSION SURFACES WITH HANGING-SILVER PLATING: Ensures the lowest distortion of any plated or clad material. Signal-masking radio frequency noise is efficiently transferred toward your utilities transformer and Earth ground—far from your sensitive components. SIGNIFICANTLY GREATER METAL MASS AND GRIP FOR OPTIMUM CURRENT DELIVERY: Includes the receptacles’ retention blades, as well as the critical ground, wire, and spade lug connections. No other AC outlet can boast such low impedance for optimum current delivery. BERYLLIUM-COPPER BASE METAL: Provides superior spring tension and long-lasting, low-impedance AC power connections. Typical materials such as brass, or even high-purity copper aided by spring and wedge devices, simply cannot equal the unparalleled retention strength of high-mass beryllium-copper. 20 amp version also available - same price.
