Synergistic Research Foundation SX Interconnect

Synergistic Research Foundation SX Interconnect

Foundation SX Interconnect is a premium analogue cable for linking compatible source equipment, DACs, preamplifiers or integrated amplifiers. It is intended to preserve a suitable line-level analogue connection, not to replace a digital interconnect or a phono cartridge lead.

Manufacturer design and technology

The manufacturer's Foundation SX interconnect uses handmade pure-silver monofilament AirString geometries within an air dielectric. Its shielding receives an SRX-derived UEF compound, and completed assemblies undergo the brand's high-voltage conditioning programme. Synergistic Research promotes these construction choices as part of an affordable, system-wide cable loom with similar design principles across analogue, digital and power leads.

Key features

• Part of the Synergistic Research Foundation SX hi-fi cable family
• Manufacturer-specified UEF electromagnetic shield treatment
• SRX-derived factory conditioning process
• Designed for a specific electrical or audio interface rather than universal connection
• Full UK retail pricing shown in the existing length/connector variants

How to choose the right cable

Confirm whether your source and destination use RCA unbalanced analogue sockets or balanced XLR interfaces. The Shopify listing currently has a single priced configuration, so the exact connector arrangement should be checked before ordering rather than assuming the same price applies to every termination. Cable length and routing matter, particularly with separate hi-fi racks.

Frequently asked questions

Can the same lead connect a turntable straight to an AUX input? Raw cartridge signals generally require a correctly matched phono stage; use an appropriate phono cable for that application.

We can review your source, amplification or loudspeakers and confirm the correct connector format, cable length and any special-order options before purchase. Synergistic Research's claimed listening benefits depend on the complete system and installation. The currently listed UK prices and variants remain unchanged.
