Overview

Synergistic Research Foundation SX USB Cable


The Synergistic Research Foundation SX USB cable brings advanced conductor technology, graphene-based shielding and proprietary signal conditioning to high-performance digital audio systems. Designed to connect music servers, streaming transports and computers to compatible USB DACs, Foundation SX incorporates technologies developed for Synergistic Research's flagship SRX cable series.

Its four 23 AWG solid-copper conductors use a geometry closely related to the company's Atmosphere SX and Galileo Discovery USB cables. Solid polyethylene insulation and dual silver Mylar/braided shielding provide the foundation for its electrical design, while 24K gold-plated contacts ensure durable connections.

Foundation SX also incorporates UEF graphene shielding and Synergistic Research's three-stage, one-million-volt Quantum Tunneling treatment. According to the manufacturer, these technologies are intended to reduce perceived noise, improve low-level detail and deliver greater tonal accuracy and soundstage dimensionality compared with the original Foundation USB.

Handcrafted in California, Foundation SX USB offers an entry into Synergistic Research's advanced digital cable technologies for dedicated two-channel listening rooms and high-resolution music streaming systems.

 

Key Features

  • Four 23 AWG solid-copper conductors: Copper Matrix construction developed for USB digital audio transmission.

  • UEF graphene shielding: Proprietary shielding technology intended to manage electrical interference around the cable and its connectors.

  • Dual-layer shielding: Silver Mylar and braided shielding with Quantum Tunneled Ground Plane technology.

  • 24K gold-plated contacts: Corrosion-resistant connector contacts for reliable connections.

  • Three-stage Quantum Tunneling: Proprietary one-million-volt conditioning using selected frequencies and pulse modulations.

  • UEF Blue Treatment: Secondary conditioning process originally developed for Synergistic Research's Blue Fuses.

  • Five-day factory burn-in: Two-stage conditioning completed before shipment.

  • Directional evaluation: Conductors are evaluated for signal direction before assembly.

  • Handcrafted in California: Individually assembled at Synergistic Research's manufacturing facility.

UEF Graphene Shielding and Signal Conditioning

Foundation SX USB uses Synergistic Research's proprietary UEF graphene-based shielding to address electrical interference in digital audio systems. Its Copper Matrix conductors and dual-layer shielding are combined with UEF treatments developed through the company's work on higher-tier cable designs.

After assembly, the cable undergoes a three-stage, one-million-volt Quantum Tunneling process involving specific frequencies and pulse modulations. Secondary UEF Blue conditioning and a five-day factory burn-in complete the manufacturing process.

Synergistic Research attributes improvements in perceived resolution, tonal realism and soundstage presentation to these technologies. Audible differences will depend on the connected components and the electrical characteristics of the playback system.

 

High-Resolution Digital Audio Integration

Foundation SX USB is intended for dedicated digital playback systems using compatible USB audio connections. It can connect a computer-based music library, dedicated music server or streaming transport to a USB-equipped digital-to-analog converter.

For customers assembling a complete Foundation SX system, the USB cable complements the series' analog interconnects, speaker cables, Ethernet cables and power cables.
