All turntables that don’t have a built in phono preamp needs a ground cable and the Jupiter cable is a high end ground cable that solves this issue. The Ground Goody Jupiter cable is compatible with any Audioquest RCA cable to create a low-distortion tonearm cable that is grounded.

Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest’s highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
AC Ground wires provide protection from current-wiring faults, but they also act as antennas. Thus, they are subject to induced radio frequency (RF) noise. This RF noise bypasses component power supplies and is typically coupled directly into a system’s most sensitive audio-video circuits. AudioQuest’s patented Ground-Noise Dissipation greatly reduces this distortion, yielding unprecedented levels of noise dissipation across the widest bandwidth (range) of radio frequencies possible. AQ’s unique circuit-topology utilizes a common-mode phase-cancelling array, in concert with proprietary dielectric materials which provide additional differential linear filtering.
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. Air, however, absorbs next to no energy, and FEP is the best extrudable solid insulation, absorbing less energy than other materials. The use of FEP Air-Tube insulation, with almost nothing but air around the solid PSC+ conductors, improves the sound of an audio system’s focus and dynamics.
Direct-Silver Plating is optimized for sound. It looks dull because there is no underlying layer of shiny, distortion-causing nickel.
