Overview

Synergistic Research Foundation SX Ethernet Cable


The Synergistic Research Foundation SX Ethernet cable is designed for high-performance digital audio systems, providing a dedicated network connection between music servers, streaming transports, audiophile network switches and network-enabled DACs. Part of the Foundation SX cable series, it brings Synergistic Research's approach to conductor design, shielding and signal conditioning to networked music playback.

In a modern streaming system, network components can introduce electrical noise that may travel through connected equipment. Foundation SX Ethernet is intended to address this concern through specialized cable construction and Synergistic Research's proprietary noise-management technologies.

Whether connecting a reference music server to an audiophile Ethernet switch or completing a dedicated two-channel streaming system, Foundation SX Ethernet offers an upgrade option for listeners seeking to refine their digital audio infrastructure.

UEF Graphene Shielding and Conditioning

Foundation SX Ethernet incorporates Synergistic Research's proprietary UEF graphene-based shielding, with a specialized compound applied to its connectors. The manufacturer developed this approach to manage interference and reduce the electrical noise it believes can affect the presentation of networked audio systems.

Following assembly, each cable undergoes high-voltage conditioning, secondary UEF Blue treatment and a five-day, two-stage factory burn-in. These proprietary processes are intended to refine the cable's performance, although audible improvements are system-dependent and have not been independently established for every application.
