Our AudioQuest GO-4 speaker cable is available ex-demo. This cable is a 5m pair and is terminated with banana plugs at both ends.
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 AudioQuest’s 30+ year history.
SOLID PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS
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 minimises 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.
DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements.

High-Inductance geometry smears sound and reduces information. Star-Quad low-inductance geometry preserves time information, preserving dynamics and clarity.
CARBON-BASED NOISE- AND CROSSTALK-DISSIPATION SYSTEM
This cable’s negative conductors are covered with partially conductive Carbon-Loaded Polyethylene. This remarkable material reduces radio-frequency garbage being fed back into the amplifier. The sonic benefit is exactly the same reduction in “hash” and improved dimensionality that comes whenever RF interference is reduced in an audio circuit. In addition, a carbon layer damps interaction between positive and negative conductors, and an external Carbon-Based Noise-Dissipation System reduces external interference.
FOAMED-POLYETHYLENE INSULATION (FOR ALL POSITIVE CONDUCTORS)
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. Tower, however, uses air-filled Foamed-Polyethylene Insulation on both conductors. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
