No matter how perfect an AC power source, distortion is added within any AC cable. Even the most sophisticated filters and power supplies cannot eliminate this Transient Intermodulation Distortion (TIM) as the induced RF noise modulates the low-level audio/video signal. NRG-Z3 cables use direction-controlled Perfect-Surface Copper (PSC) strands in a Semi-Solid Concentric conductor arrangement in which strands are packed more tightly and never change position within the bundle. This construction significantly reduces strand interaction distortion. The extremely pure and smooth-surface PSC conductors minimize distortion caused by grain boundaries which exist in any metal conductor. NRG-Z3's Ground Noise-Dissipation System and direction-controlled Silver-Plated shield conductors efficiently drain RF noise from the line and neutral shields to ground via the third “ground” pin. In addition. NRG-Z3's common-mode phase-cancelling array provides additional differential linear filtering. The net result is powerful, dynamic and immersive! AudioQuest's NRG-Z3 cables come in a variety of legnths to meet your needs.
