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 as the induced RF noise modulates the low-level audio video signal. NRG-Y2 cables use direction-controlled Long-Grain-Copper 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 reduces distortion.
