Delta EF Mains Cable

Shunyata Research

The Delta EF power cord has the same VTX™ conductors used in the Delta NR and includes CopperCONN® plugs. It features a custom designed and built Shunyata Research connector that is smaller, allowing connections to obstructed AC inlets. Delta EF does not include noise reduction.

The EF Series are specialty power cables designed for electronics that have obstructed power-inlet entries. Many entertainment systems are installed in custom cabinetry that require exceptional flexibility and compact connectors for easy routing through small openings.

Shunyata Research has created the CopperCONN® EF-C15 power connector that features a compact physical size and yet retains all the capabilities of Shunyata’s full-sized CopperCONN® connectors. It has high grip, pure copper contacts and oversized contacts to accept 8 gauge wire without ‘downsizing’ the wire.

The Delta EF and Alpha EF power cables offer near reference level performance with exceptional ease of use and flexibility.

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.

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 length are available.
