High-quality replacement AC power cable (15-ft.)
Our take on the AudioQuest NRG-X2 by Crutchfield's Steve Kindig
An easy performance upgrade
Many components come with a detachable AC power cord. That gives you the flexibility to upgrade to a higher-quality cable. It may surprise you, but simply replacing your component's stock power cord with a low-distortion AC power cable can noticeably improve your system's picture and sound quality. At the component end, AudioQuest's NRG-X2 features a 2-pole "C17" connector, which is common on A/V receivers, integrated amps, and power amps.
Why power cords make a difference
The AC power that feeds your gear is really the foundation of your system's audio and video performance. Even if you've plugged your components into a power conditioner to clean up the current coming out of your wall, a flimsy stock power cord can act as an antenna for airborne interference that subtly degrades high-resolution audio and video signals.
Advanced materials and construction
The NRG-X2 uses two stranded Semi-Solid Concentric Packed Conductors made of high-purity Long-Grain Copper. Compared to typical stranded cables, this approach uses fewer, larger strands that don't change position down the length of the cable. While solid conductors are the best solution to strand distortion, Semi-Solid Concentric Packed Conductors avoid much of the distortion of stranded conductors

Semi-Solid Concentric Packed Conductors: Semi-Solid Concentric Packed Conductors are used in AudioQuest's NRG-X2 AC power cable as a cost-effective, flexible alternative to typical stranded conductors. Semi-Solid Concentric Packed Conductors use fewer, larger strands that do not change position down the length of the cable. While solid conductors are the complete solution to strand distortion, Semi-Solid Concentric Packed Conductors avoid many of the distortion mechanisms of stranded conductors.
Long-Grain Copper (LGC): LGC allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding "loss" without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. NRG-X2 cables use LGC strands in a Semi-Solid Concentric Packed Conductor arrangement.
Helical-Array Geometry: The relationship between conductors defines a cable's most basic electrical values (including capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly effect performance. Helical-Array (such as circular-spiral) construction allows for significantly better dynamic contrast and clarity than if the same conductors were run in parallel or as multiple twisted pairs.
Cold-Welded System: The NRG-X2's 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.
Connectors: The Audioquest NRG-X2 power cable features a C17-2 pole connector on one end to plug into your audio/video electronic component and a 2-prong North American AC connector on other end to plug into your AC wall outlet.
