Our take on the Audioquest NRG-4 by Crutchfield's Steve Kindig
A custom cable for AQ's finest power conditioners
AudioQuest's Niagara 5000 and Niagara 7000 power conditioners are incredibly effective at eliminating AC line and ground noise in high-performance audio and A/V systems. The one thing both models lack is a power cord. So we asked AQ to build us a high-quality cable with the special 20-amp IEC-C19 connector at the component end.
The AudioQuest NRG-4 is a low-distortion AC power cable that will help AQ's Niagara conditioners maximize the sound and picture quality of your system.
Advanced materials and construction for lower distortion
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 Perfect-Surface Copper+ eliminates harshness and increases clarity compared to other high-purity coppers.
The Counter-Spiral geometry minimizes conductor interaction while maintaining a fixed low inductance relationship between conductors. 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.

Audioquest NRG-4 Reviews

Thanks for submitting your review
AudioQuest NRG-4 (20A): This high-quality AC power cable features a special 20-amp IEC-C19 connector at the component end to accommodate AudioQuest's Niagara 5000 & 7000 power conditioners (sold separately). On the other end of this power cable is a standard 3-prong North American AC connector to plug into your AC wall outlet.
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-Base Noise-Dissipation & 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 other materials.
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 & Connectors: 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.
