Synergistic Research Foundation XL Ethernet

Foundation XL Ethernet At its heart, Foundation XL is a scaled-down distillation of SRX XL—handmade in our California factory using the same core technologies first pioneered in our flagship cable loom. Just as SRX XL evolved from SRX with greater conductor density and refined treatments, Foundation XL builds on Foundation SX with 33% more pure silver AirString geometries, each suspended in an air dielectric to reduce dielectric interaction and increase resolution. We apply the same SRX XL UEF Compound to Foundation XL’s matrix shielding to lower the noise floor without constraining dynamics or transparency. Every cable is then treated with the identical long-duration, high-frequency conditioning process developed for SRX XL—enhancing dimensionality, tonal accuracy, and high-frequency refinement. Each cable includes Purple and Gold UEF Carbon Tuning Discs, letting you voice your cables to system and taste—or run them clean. The choice is yours. Foundation XL brings the exact same tec
