Solid Perfect-Surface Copper+ (PSC+) Solid conductors prevent both electrical and magnetic interaction strand-to-strand interaction, major sources of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the fields within a conductor, and for the magnetic fields that extend outside the conductor.

The astonishingly smooth and pure surface of all AudioQuests’s Perfect-Surface metals nearly eliminates harshness and greatly increases clarity compared to lesser materials. Extremely high-purity Perfect-Surface Copper+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N, and other coppers.

Asymmetrical Double-Balanced Geometry Purpose designed for single-ended applications, Asymmetrical Double-Balanced Geometry offers a relatively lower impedance on the ground for a richer, and more dynamic experience. While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two for cleaner, quieter performance.

Polyethylene Air-Tube Insulation Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy.

Some of this energy is stored and then released as distortion. AudioQuest, however, uses Polyethylene Air-Tube Insulation on both conductors, for increased geometry stabilization and improved clarity.

Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Polyethylene Air-Tube Insulation, with its high air content, causes much less of the out-of-focus effect common to other materials. Carbon-Based 3-Layer Noise-Dissipation System (NDS) It's easy to accomplish 100% shield coverage.

Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal.

NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground. Cold-Welded, Direct Silver-Plated Pure Purple Copper Terminations Cold-Welded, Direct-Silver Plated Pure Purple Copper Terminations.

Direct-Silver Plating is optimized for sound. It looks dull because there is no underlying layer of shiny, distortion-causing nickel.
