AudioQuest NRG-4 AC Power Cable

Audioquest Authorized Dealer

AudioQuest NRG-4 AC power cables embrace the benefits of multi-position carbon-based noise-dissipation and cross-talk-dissaipation systems, including improved dimensionality and reduced radio-frequency garbage. They have the counter-spiral construction of conductors to create a clear, focused signal.

  • Compatible with most devices that use 2- or 3-pole IEC 15 connectors for a reliable connection.
  • Counter-Spiral HyperLitz Geometry reduces distortion.
  • Solid 13 AWG PSC+ and PSC conductors provide a clear signal.
  • Cold-welded connectors for durability.

NRG-4 3-Pole AC Power Cable No matter how perfect an AC power source, distortion is added within any AC cable, especially within a stranded cable. Even the most sophisticated filters and power supplies cannot eliminate this cable-induced distortion.

SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS: NRG-4 uses extremely high-purity Perfect-Surface Copper+ conductors. All conductors are solid, which prevents strand interaction, a major source of distortion. Surface quality is critical because a conductor can be considered a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. The astonishingly smooth and pure PSC+ eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other coppers. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor.

MULTI-POSITION CARBON-BASED NOISE-DISSIPATION and CROSS-TALK-DISSIPATION SYSTEMS (INSULATION): The negative conductors in NRG-4 are insulated with partially conductive Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency garbage from being fed back into the amplifier. The sonic benefit is exactly the same reduction in “hash” and better dimensionality that comes whenever RF garbage is reduced in an audio circuit. NRG-4 uses Foamed-Polyethylene Insulation on its positive conductors because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to

COUNTER-SPIRAL GEOMETRY: NRG-4 power cables have an inner circular array of positive conductors spiraling in one direction. Around this inner group are the negative conductors spiraling in the opposite direction. Even while the positive and negative conductors are crossing each other instead of being parallel, the relationship between the positive and negative groups is fixed and non-changing, adhering to one of AudioQuest’s most basic design tenets: consistency. The result is an astonishing clarity, like focusing a camera lens you had no idea was so far out of focus.

COLD-WELD SYSTEM: This novel plug design enables a perfect heat-free connection between cable and plug. The connection between the plug and conductors is made using AQ’s Cold-Weld System, which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Weld System refers to a combination of high pressure at the point of contact and the use of copper- or silver-impregnated paste.
