AudioQuest® NRG-1 AC Power Cable with star-quad geometry and cold-weld system

Proposition 65 Warning for California Residents

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 Long-Grain Copper (LGC) Conductors

Solid conductors eliminate strand-interaction distortion. Evergreen’s solid Long-Grain Copper 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.

Star-Quad Geometry

The relationship between conductors defines a cable’s most basic electrical values (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 affect the sound. The Star-Quad construction of NRG-1 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel.

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.
