PUSHING THE BOUNDARIES OF DIGITAL AUDIO

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.

PRECISION BEYOND EXPECTATION

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.

 


 

TECHNOLOGY

TAPc

TAP (Transverse Axial Polarizer) is a patent-pending technology developed by Shunyata Research to enhance the performance of its reference signal cables. The evolution of this technology has led to the creation of TAPc, a groundbreaking advancement that significantly reduces the size of the modules, enabling their application across a broader range of cables, including power cords, interconnects, digital cables and speaker cables.

The sonic results of TAPc technology include a profound drop in perceived noise floor, effortlessly portrayed dynamics, and an exceptional rendering of timing and coherency. These benefits are unique to TAPc, setting it apart from any competing product or technology. Even to an untrained ear, the effects of TAPc are immediately apparent and consistently repeatable across various components and systems. Essentially, the TAPc modules act as force multipliers, elevating the listening experience to levels many would not have thought possible.

KPIP v2 tech icon

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 process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade.

PMZ

Shunyata Research produces select cables using a ‌Precision Matched Z (‌‌PMZ) concept. This means that tolerances of the conductor surface, dielectric extrusion, and the precision of the braided shield are held to minute variances. To achieve these tight tolerances, the extrusion and braiding machines must be run at one-quarter speed during the manufacturing process. (Note: Z means impedance)

 

Shunyata's CMode tech icon

Common-mode noise is different than differential noise and is much more difficult to measure and eliminate. For the purest signal possible, Shunyata Research has developed a CMode filter that effectively reduces common-mode noise without introducing the sonic compression effects associated with conventional filters. It reduces high-frequency noise distortion while delivering an analog ease and palpable background silence that closes the gap between digital and analog systems.
