Low-Distortion 3 Pole Power Cable Long-grain copper (LGC) and Silver-Plated Drain Wires Noise-Dissipation: Quiet Background and Minimal Circuit Misbehavior Due to Direction-Controlled Conductors and Shields ZERO Tech (No Characteristic Impedance) for Uncompressed Current Transfer THE CHALLENGE: No matter how perfect an AC power source is, distortion is added to 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.THE SOLUTION: NRG-Y3 cables use direction-controlled Long-Grain-Copper (LGC) 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 greater purity and less complicated grain structure within LGC copper further reduce distortion.In addition, NRG-Y3’s direction-controlled Silver-Plated shield conductors efficiently drain RF noise from the line and neutral shields to the ground via the third “ground” pin. The net result is powerful, dynamic, and immersive!
