Product Description

The Ethernet cable was made for sister company CIS (Clear Image Scientific) for high speed medical imaging applications. Shunyata Research incorporated its exclusive technologies into the Venom, Alpha and Sigma high-speed Ethernet cables, and has quickly made them the most sought after products in their category.

Precision Matched ZTechnology

The most fundamental of three critical ethernet cable technologies is termed Precision Matched Z (PMZ) conductors. Designer Caelin Gabriel’s research into high-speed signal transmission found that the precision with which any digital cable conductor is constructed has a profound impact on performance. Widely differing manufacturing variances will lead to signal distortions that are clearly audible in any system designed for high-fidelity. To achieve the benefits of PMZ, Shunyata Research produces the Venom, Alpha and Sigma ethernet cables using extrusion and braiding machines that are run at one-quarter normal speeds during the manufacturing process. This virtually eliminates the micro distortions otherwise inherent to high-speed signal transmission through traditionally extruded conductors. While costly, this process delivers superior timing, clarity and dynamics in sound when compared to any other ethernet cable produced through normal processes.

Kinetic Phase Inversion Process™
The second and equally effective technology applied to all three Shunyata Ethernet designs is the now famous Kinetic Phase Inversion Process™ (KPIP). KPIP is a proprietary Shunyata Research wire-treatment process that effectively eliminates break-in and improves the characteristic performance of all signal and power cabling it is applied to. These improvements are magnified when applied to high-speed signal conductors because they are more prone to signal degradation and micro distortions within conductors than comparably slower speed analog signal cables.

Common Mode Filter Technology
Alpha and Sigma Ethernet Models
For the purest signal possible, Shunyata Research has applied it’s own custom-made common mode filter technology (CMode Filter) to both the Alpha and Sigma ethernet models. As the name implies, these CMode Filters (1 is applied to the Alpha model, 2 in the Sigma) eliminate high-frequency noise distortion shared between digital electronics and the area that surrounds them. Without adding any impedance of their own, these custom-made noise filters deliver sound with an analog ease and palpable background silence that will close the gap between digital and analog front end performance. Taken together, these technologies elevate the performance of the Venom, Alpha and Sigma Ethernet cables beyond anything currently available, at any price. Listen, compare for yourself and discover the best resolution possible from ethernet connected sources!
