The Shunyata Research Sigma V2 NR power cord is the ultimate expression of Shunyata Research’s Noise Reduction series.

Six-gauge VTX™ (hollow-core) conductors enable it to handle high-powered amps & yet it's surprisingly flexible. CopperCONN®, pure copper connectors, are the best. KPIP™ eliminates burn-in issues. The standard length is 1.75m. Sigma NR power cord builds on its predecessors with massive VTX™ conductors & CopperCONN®, solid copper connectors. Low-resistance to peak current (DTCD™) offers superior performance w/current-hungry amps. Its wide-bandwidth noise filter reduces power-line & component noise, which is ideal for source components, amps & digital systems. Sigma NR's materials & tech raise the performance bar.


Shunyata Research uses ultra-pure OFE Alloy-101 copper with conductivity of 101% IACS, certified by ASTM F68. Their exclusive VTX conductors minimize skin effects and random eddy currents. Caelin Gabriel developed KPIP to eliminate burn-in and cryo treatment virtually. CCI filters reduce noise without inhibiting DTCD. CopperCONN connectors contain pure copper contacts for enhanced performance.
