Deliver Cleaner Power to Your Stereo ComponentsNo matter how perfect an AC power source, distortion is added within any AC cable, especially within a stranded cable. Even the most sophisticated filters and power supplies cannot eliminate this cable-induced distortion. The NRG-Z2 AC cable uses Perfect-Surface Copper + (PSC+) in a 7-strand Semi-Solid Concentric conductor arrangement. The astonishingly smooth and pure Perfect-Surface processed conductors minimize distortion caused by grain boundaries and surface discontinuities which exist in any metal conductor. Also utilizes silver-plated drain wires.
