Sigma-X Digital Ethernet Cable

Inspired by collaboration with the industry’s most renowned mastering engineers, Shunyata Research has developed the most advanced digital cabling systems in our award-winning history. Sigma-X digital cables are engineered using patented and proprietary technologies that enhance signal fidelity by reducing cable induced jitter that results in temporal displacement and phase distortion.

Sigma-X digital cables are engineered for those who demand unrivaled levels of clarity and resolution while preserving a natural tonal presentation. These technical innovations produce to an ultra-low noise floor, enabling a sonic experience that reveals the most elusive details with superb precision.

Sigma-X digital cables transcend the limitations of conventional digital playback, delivering a musical experience that rivals the purity and depth of analog systems. They allow even the most complex digital systems to reproduce sound as if cut directly from an analog master tape. 

For listeners seeking ultimate realism, Sigma-X reveals the intricate details and nuances only experienced with live musical performances.

‌‌ArNi® Conductors
Shunyata developed this wire to be the finest quality wire available for audio purposes. The process begins with the highest purity of copper available – OFE C10100 or Ohno (single crystal). The conductors are then formed into virtual hollow tubes which eliminates skin effects as well as eddy current distortions. Premium fluorocarbon insulation protects the conductors and minimizes dielectric absorption and re-radiation, this greatly improves resolution and clarity. The wire then undergoes Shunyata's proprietary KPIP™v2  process for optimal conductivity.

Fluorocarbon Dielectrics
These ultra-high quality insulators are usually only found in wire used in the aerospace industry, satellites and the most expensive audiophile cabling. Fluorocarbon has special electrical characteristics; very low dielectric absorption, high dielectric strength and exceptional heat resistance.  When used in audio and power cables these dielectric materials reduce the perception of dynamic compression and improve low-level resolution and overall clarity.

Transverse Axial Polarizer (TAPc)
This is a Shunyata Research patent pending technology developed to improve the performance of their reference cables. The TAPc technology is a radical advancement of their original TAP technology which enables a significant reduction in the size of the modules – which for the first time allows this technology to be applied to power cords.  The sonic results of TAPc include a cavernous drop in perceived noise floor, effortlessly portrayed dynamics and a superb rendering of timing and coherency. The sonic benefits of the TAPc technology are quite simply unique and cannot be replicated by any competing product or technology. Even to an untrained ear, the effects of the TAPc are immediately apparent and repeatable across a variety of components and systems. In essence, the TAPc modules are force-multipliers that elevate the listening experience to a level many would not imagine possible.

Hybrid Polarizing Filter (TAPc & CMode)
For the purest signal possible, Shunyata Research has combined its patent-pending TAPc technology (trans-axial polarizer) and CMode filter (common mode filtering technology) into a single hybrid module. The TAPc polarizer reduces polarization distortion while the CMode filter simultaneously reduces high-frequency noise distortion, delivering analog ease and palpable background silence that will close the gap between digital and analog front-end performance.

Kinetic Phase Inversion Process (KPIP) v2
Shunyata Research’s proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP v2™ processing which refines conductor metals at a molecular level. This dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation. When compared to the original KPIP process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade.
