Sigma EF

The Sigma EF Model power cord is identical to its sibling Sigma NR power cord in every respect except two areas – Sigma EF power cords do not have the NR model’s built-in filter network, and Sigma EF model power cords are constructed using a very flexible hollow external tube making the EF model narrower and extremely flexible so that it can be routed around any tight corner. The Sigma EF offers exceptional performance when used with all electronics and speakers that require either greater flexibility in the body of the power cord and can do without the Sigma NR model’s built-in filter network.

Standard length of cable is 1.75 metre.

The Sigma EF power cord was created for applications that will benefit from the Sigma EF model’s greater flexibility. The Sigma EF model is housed in a more slender and more flexible outer tube. In terms of parts and material quality, the Sigma EF Model power cord is identical to its sibling Sigma NR power cord in every respect except two areas. Sigma EF power cords do not have the NR model’s built-in filter network. Sigma EF model power cords are constructed using a very flexible hollow external tube, making the EF model narrower and extremely flexible so that it can be routed around any tight corner. The Sigma EF offers exceptional performance when used with all electronics and speakers that require either greater flexibility in the body of the power cord and can do without the Sigma NR model’s built-in filter network. Examples of intended applications would be the Hydra Denali and other components that may not need the Sigma NR’s built-in filter networks for added noise reduction.

General Application recommendations: Hydra Denali power conditioners, Amplifiers, Pre-amplifiers, active speakers etc.
