Synergistic Research Foundation SX Phono Cable

Synergistic Research Foundation SX Phono Cable

Foundation SX Phono Cable is hand-made in Synergistic Research's Southern California factory with pure silver mono-filament Air String conductors in an air dielectric, using the same woven copper matrix shield construction found on Atmosphere SX and Galileo Discovery phono cables. It uses a UEF Compound and High Voltage Long Duration Conditioning Process first developed for the flagship SRX cable loom, delivering a low noise floor and black background with dynamics, detail, and holographic soundstaging. Included Gold and Purple Carbon Tuning Discs let you custom-voice the cable to your system, or run it straight. Available in RCA, XLR, or DIN, and upgradeable to SR XLR high-purity silver connectors. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you match this phono cable to your tonearm and phono stage.
