Shunyata Research’s SIGMA-X Digital Cables are designed to deliver reference-level performance in digital audio systems. Whether for AES/EBU, S/PDIF, or clock applications, the Sigma-X series combines advanced noise suppression technologies and superior materials to redefine digital signal fidelity.

Performance Redefined

The Sigma-X Digital Cables eliminate common sources of signal degradation, including electromagnetic interference, jitter, and common-mode noise. This ensures unparalleled accuracy, detail retrieval, and soundstage coherence, unlocking the full potential of your digital system.

Cable Types

• AES/EBU: Twin axial geometry design with OCC copper conductors and fluorocarbon dielectric, featuring 110-ohm characteristic impedance.

• S/PDIF: Coaxial design with silver-plated copper (SPC) conductors and PTFE dielectric, featuring 75-ohm characteristic impedance.

• Clock-50: Coaxial design with SPC conductors, PTFE dielectric, and 50-ohm characteristic impedance.

• Clock-75: Coaxial design with SPC conductors, PTFE dielectric, and 75-ohm characteristic impedance.

Key Features

• Transverse Axial Polarizer (TAP): Reduces electromagnetic interference for a lower noise floor and enhanced clarity.

• CMode Noise Reduction: Minimises common-mode noise, preserving natural tonal balance and dynamic range.

• Precision-Matched Conductors: Ensures stable signal integrity with minimal jitter and time smear.

• KPIP™ v2 Process: Pre-treated to eliminate the need for lengthy burn-in, offering optimal performance immediately.

Crafted for professionals and audiophiles alike, the Sigma-X Digital Cables represent Shunyata Research’s uncompromising commitment to innovation and excellence in digital connectivity.
