NRG-Z2 cables use direction-controlled Perfect-Surface 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 extremely pure and smooth-surface PSC+ conductors minimize distortion caused by grain boundaries which exist in any metal conductor. In addition, NRG-Z2’s direction-controlled Silver-Plated shield conductors efficiently drain RF noise from the line and neutral shields to ground via the third “ground” pin. The net result is powerful, dynamic and immersive!
