Shunyata Research Sigma NR V1 C19 Power Cord 1.75M *SOLD*
The Sigma NR power cord builds upon the worldwide success of its predecessors with massive 6-gauge (VTX™) hollow-core conductors and Shunyata’s own CopperCONN®, solid copper connectors. The Sigma NR’s meticulous design and vanishingly low-resistance to peak current (DTCD®) delivers unparalleled performance when used with even the most current-hungry amplifiers. Its built-in wide-bandwidth noise filtration system reduces power-line and component generated power supply noise, making it an ideal choice for source components, power amplifiers and digital systems. Shunyata’s Sigma NR power cord’s advanced materials and standard-setting technology raise the performance bar for others to follow.
Shunyata Research uses only the highest purity of copper available for the production of its wire products. OFE Alloy 101 or C10100 is the highest grade of copper with a minimum 99.99% purity and a conductivity rating of 101% IACS. OFE stands for oxygen-free electrolytic and supersedes the term OFHC (oxygen-free high conductivity). C10100 is the only grade of copper that comes with a written certification of purity. Certified by ASTM F68 C10100.
KPIP™ (Kinetic Phase Inversion Process) was developed by Caelin Gabriel after years of research into the underlying causes of various effects such as burn-in, wire directionality and the effects of cryogentic treatment. He discovered that there was an underlying core principle that burn-in and cryogenics only “partially” addressed. Once the governing principle was understood it became possible to create a processing technique and machine that could virtually eliminate the need for burn-in and cryogenic treatment.
CCI™ filters have the unique ability to reduce component-generated power line noise without inhibiting DTCD® (dynamic transient current delivery). This unique filter element prevents power line noise from one component contaminating the other adjacent electronic components. Shunyata Research’s CCI™ filter modules consist of proprietary multi-stage filters that reduce power supply-generated noise without the use of heavy transformers, coils or large capacitors.
Many audiophile grade connectors are made from brass or bronze. While some may get a plating of silver, gold or rhodium, the majority of the current is carried by the contact’s base-metal. CopperCONN® connectors contain pure copper contacts which has a much higher conductivity that brass. The difference in performance is clearly audible.
