The Delta EF power cord was created for applications that have a restricted area component or speaker IEC entry point. The Delta EF model uses a slender model, solid-copper female connector that will fit into even the most narrow area component IEC opening. In terms of parts and material quality, EF Model power cords are identical to Shunyata Research’s NR power cords in every way except one – EF power cords do not have the NR model’s built-in filter networks. EF model power cords offer exceptional performance when used with all electronics and speakers that require either greater flexibility from power cords or a slender IEC connector to make an unobstructed connection to the component or speaker.
Examples of restricted area IEC electronics and speakers that would benefit from EF model power cords are some models of Vandersteen speaker, Devialet electronics, Pass Lab’s Aleph models
General Application recommendations: Shunyata Research Hydra Denali power conditioners, Amplifiers with restricted area IEC, Pre-amplifiers, active speakers etc.
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.
