Product Details

Synergistic Research Foundation XL USB Cable

Foundation XL USB Cable brings the core technologies developed for Synergistic Research's flagship SRX XL cable line to a USB cable, built with 4x Mk II Copper Matrix conductors. 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 than its predecessor Foundation SX. Included Gold and Purple Carbon Tuning Discs let you voice the cable to your system, or run it clean. Available in 1, 2, 3, and 5 meter lengths. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you match this USB cable to your DAC and source.
