Delta NR Mains Cable

Shunyata Research

The Delta NR power cord is the most affordable of the NR (noise reduction) power cords from Shunyata Research. NR power cords that have built-in filters that reduce power line noise. Delta NR features VTX™ (hollow-core) conductors and pure copper CopperCONN® connectors. The 10 gauge conductors make it ideal for high-power amplifiers and source components.

The Delta power cables feature ultra-pure OFE copper, woven into Shunyata’s own VTX™ hollow-core conductors, which are then connected to Shunyata’s exclusive CopperCONN® connectors. CopperCONN® connectors contain pure copper contacts — not the common plated brass and bronze contacts used in the vast majority of power cords at this price-point. The Delta NR is the first in Shunyata Research’s NR Series power cables to incorporate ‘on-board CCI™ filters’ that provide power conditioning to each individual component.

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.

Shunyata Research's exclusive ‌VTX™ conductors are made in the shape of virtual tubes. The core of the conductor is completely hollow minimizing skin effects and random eddy currents. They are produced using OFE Alloy-101.

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.

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.

Standard length is 1.75m but alternative lengths are available.
