GO-4 is a step up in the Star-Quad series by virtue of offering higher-quality metal and the addition of AudioQuest’s patented Dielectric-Bias System. These two advancements significantly better the performance of Type 4, the most successful speaker cable in our 30+ year history.
SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS: GO-4 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.
CARBON-BASED NOISE-DISSIPATION and CROSS-TALK-DISSIPATION SYSTEMS (INSULATION): The two negative conductors in GO-4 are insulated with partially conductive Carbon-Loaded Polyethylene. This remarkable material damps radio-frequency garbage from being fed back into the amplifier. The sonic benefit is exactly the same reduction in “hash” and better dimensionality that comes whenever RF garbage is reduced in an audio circuit. GO-4 uses air-filled Nitrogen-Injected Foamed-Polyethylene Insulation on its positive conductors because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials.
