Great-Sounding Cable with Perfect-Surface Copper+ Conductors
AudioQuest GO-4 15 AWG speaker cable uses extremely high purity Perfect-Surface Copper+ (PSC+) conductors. All conductors are solid, which prevents strand interaction, a major source of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor.
The astonishingly smooth and pure Perfect-Surface 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.
The Advantage of Solid Conductors
All four of GO-4's conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the single greatest source of distortion, often causing a somewhat harsh, dirty and confused sound. Solid conductors are the most important ingredients enabling GO-4’s very clear sound. Whether a conductor is solid or stranded, skin-effect is a prime distortion mechanism in speaker cables. AudioQuest GO-4 very simply keeps this effect out of the audio range by using conductor sizes that are below the threshold for audible distortion.
All insulation slows down the signal on the conductor inside. When insulation is un-biased, it slows down parts of the signal differently, a big problem for very time sensitive multi-octave audio.
AudioQuest’s DBS creates a strong stable electrostatic field, which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS packs batteries will last for years. A test button and LED allow for the occasional battery check.
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 effect the sound. The spiral construction of GO-4 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel. The specific 4-cross geometry used in GO-4 maximizes this advantage.
SST (Spread Spectrum Technology)
Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid round or tubular) have the fewest discontinuities, any particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. The four different SST-determined conductor sizes used in GO-4 allow an exceptionally clear, clean and dynamic sound.
AudioQuest offers a wide range of high quality connectors that allow GO-4 to be securely attached to any type of equipment. Quality is in the low distortion sound, not necessarily in the eye-candy effect. AQ ends are either a dull looking gold or silver because these metals are plated directly over the connector. There is no shiny and harsh sounding nickel layer underneath.
AudioQuest PK-spade lugs are soft because better metal is soft, and facilitates a higher quality connection. For pieces requiring a banana plug or BFA connector the AQ PK-BFA/Banana provides unprecedented performance over conventional brass versions.
