Solid conductors prevent strand interaction, which is the greatest single source of distortion in an audio
cable or in an AC power cable. The less complicated grain structure and fewer impurities within LGC copper
significantly reduce distortion compared to normal high-purity copper. The Quad-Helix spiral creates a fixed
low-inductance relationship between conductors. The NRG-1's RF Stopper filters Radio Frequency Interference in both directions. It reduces outside interference entering the equipment, and it prevents equipment generated interference (as from all digital equipment and tuners) from reaching other equipment in the system.
