AudioQuest® NRG-1.5 AC Power Cable with copper conductors and star-quad geometry

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 Perfect-Surface Copper+ (PSC+) Conductors:

NRG-1.5 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.

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.
