NRG-3 uses solid Perfect-Surface Copper (PSC) conductors in a Self Shielding Counter-Spiral Hyperlitz. Solid conductors prevent strand interaction, which is the greatest single source of distortion in an audio cable or an AC power cable. The nearly perfect surface finish and interior grain structure of PSC copper dramatically reduce distortion compared to OFHC or other metals. The Counter-Spiral geometry minimizes conductor interaction while maintaining a fixed low-inductance relationship between conductors.
NRG-3 two RF Stoppers filter Radio Frequency Interference in both directions. They prevent outside interference from entering the equipment, and they prevent equipment generated interference (from all digital equipment and tuners) from reaching other equipment in the system.
