Shunyata Research Sigma-X Ground Cable Base 3M

Shunyata Research Sigma-X Ground Cable

The Shunyata Research Sigma-X ground cable brings advanced noise-reduction technology and substantial 6-gauge VTX-Ag conductors to a dedicated audio grounding system. Designed to address unwanted electromagnetic and radio-frequency noise, it combines specialized filter modules with carefully selected materials for listeners refining their system’s grounding connections.

Targeted Noise-Reduction Technology

Sigma-X incorporates Shunyata Research’s TAPc (Transverse Axial Polarizer) and CMode common-mode noise-reduction technologies. These modules encircle the conductors to dissipate EMI and RF noise. Shunyata describes the intended listening benefits as greater harmonic detail, more dimensional imaging, and a stronger sense of musical weight and scale.

Purpose-Built Construction

Its 6-gauge VTX-Ag cable design uses ArNi OFE conductors and a fluorocarbon dielectric. STIS v3 connectors provide an interchangeable termination system, while four days of KPIPv2 conditioning complete the cable’s preparation before use.
