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+ CONDUCTORS (PSC+): 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.
RF NOISE STOPPERS: Made from ferrite, the RF Noise Stoppers suppress and then dissipate (as low-level heat) high-frequency interference, eliminating layers of A/C grunge for a clear, quiet presentation.
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.
