Description
The flagship Synergistic Research SRX XL AC Power Cable is engineered for reference-level audio systems where ultimate performance matters. Handcrafted in California, the SRX XL combines Synergistic Research’s most advanced UEF technologies, Active Shielding, and a complex 14-geometry architecture to deliver dramatically lower noise, greater realism, and exceptional musical transparency.

Built with multiple 99.9999% pure silver conductors, Silver Air Strings, Silver Air Ribbons, Graphene-enhanced UEF Shielding, and Long Duration High Voltage Conditioning, the SRX XL allows connected components to perform with greater speed, dimensionality, tonal richness, and dynamic authority.
Listeners can expect:
-
Lower noise floor and blacker backgrounds
-
Improved soundstage depth and image focus
-
Greater low-level detail and transient speed
-
Enhanced bass control and dynamics
-
Richer harmonic texture and tonal realism
-
More natural and effortless musical presentation
Included Gold and Master Carbon Fiber UEF Tuning Modules allow fine-tuning of warmth, detail, liquidity, and extension to perfectly match your system and listening preferences.

| Silver Solder | 4% |
| Quantum Tunneling Process | Before the Active Power Supply is incorporated, all connections and cabling are treated with 1,000,000 volts of electricity at specific frequencies and pulse modulations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely while improving Active Shielding efficiency and low-level detail retrieval. |
