Synergistic Research Foundation XL Phono Cable

Synergistic Research Foundation XL Phono Cable

Foundation XL Phono Cable brings the core technologies developed for Synergistic Research's flagship SRX XL cable line to phono, with geometry and shielding further optimized for the ultra-low-voltage phono signal. It uses 6x (RCA) or 9x (XLR) pure silver Air Strings in an air (sealed) dielectric, 33% more than Foundation SX, for harmonic nuance, ambient detail, and a pitch-black background. Every cable uses SRX XL Matrix Shielding with Graphene and is treated with SRX XL High Voltage Conditioning, bringing Foundation XL's voicing closer to the flagship SRX XL line. Included Gold and Purple Carbon Tuning Discs let you voice the cable to your system, or run it clean. 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.
