No matter how perfect an AC power source, distortion isadded within any AC cable, especially within a stranded cable. Even the mostsophisticated filters and power supplies cannot eliminate this cable-induceddistortion. SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS: NRG-4 usesextremely high-purity Perfect-Surface Copper+ conductors. All conductors aresolid, which prevents strand interaction, a major source of distortion. Surfacequality is critical because a conductor can be considered a rail-guide for boththe electric fields within a conductor, and for the magnetic fields outside theconductor. The astonishingly smooth and pure PSC+ eliminates harshness andgreatly increases clarity compared to OFHC, OCC, 8N and other coppers. Thesuperior purity of PSC+ further minimizes distortion caused by grainboundaries, which exist within any metal conductor. MULTI-POSITION CARBON-BASED NOISE-DISSIPATION andCROSS-TALK-DISSIPATION SYSTEMS (INSULATION): The negative conductors in NRG-4are insulated with partially conductive Carbon-Loaded Polyethylene. Thisremarkable material damps radio-frequency garbage from being fed back into theamplifier. The sonic benefit is exactly the same reduction in hash and betterdimensionality that comes whenever RF garbage is reduced in an audio circuit. NRG-4 uses Foamed-Polyethylene Insulation on its positive conductors becauseair absorbs next to no energy, and Polyethylene is low-loss and has a benigndistortion profile. Thanks to all the air in Foamed-PE, it causes much less ofthe out-of-focus effect common to other materials. COUNTER-SPIRAL GEOMETRY: NRG-4 power cables have an innercircular array of positive conductors spiraling in one direction. Around thisinner group are the negative conductors spiraling in the opposite direction. Even while the positive and negative conductors are crossing each other insteadof being parallel, the relationship between the positive and negative groups isfixed and non-changing, adhering to one of AudioQuest’s most basic designtenets: consistency. The result is an astonishing clarity, like focusing acamera lens you had no idea was so far out of focus. COLD-WELD SYSTEM: This novel plug design enables a perfectheat-free connection between cable and plug. The connection between the plugand conductors is made using AQ’s Cold-Weld System, which provides a superiorconnection that ensures that the structural integrity of the conductor is keptcompletely intact.   The Cold-Weld Systemrefers to a combination of high pressure at the point of contact and the use ofcopper- or silver-impregnated paste.
