AudioQuest NRG-2 Power Cable: Never Tried a Cable Upgrade? Find Out What You've Been Missing
Audioquest's NRG-2 uses solid Long-Grain Copper (LGC) 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 less complicated grain structure and fewer impurities within LGC copper significantly reduce distortion compared to normal high-purity copper. The Counter-Spiral geometry minimizes conductor interaction while maintaining a fixed low-inductance relationship between conductors.
No matter how perfect an AC power source, distortion is added within any cable carrying AC, especially within any stranded cable. Even the most sophisticated power supplies and filters cannot completely eliminate these upstream irregularities.
NRG-2's RF Stopper filters Radio Frequency Interference in both directions. This prevents outside interference from entering the equipment and prevents equipment generated interference (from all digital equipment and tuners) from reaching other equipment in the system.
