UEF Black Power Cable

Once you go Black.

We often hear people ask how the last few feet of a chain of AC cables spanning miles can have an effect on the sound of an audio system. The answer is that electricity or electrons don’t actually travel through a wire but rather vibrate creating a wave with many factors affecting how this wave propagates from the power station to your home. Change any of these factors and you change the nature of the electricity in your system. Using the same UEF technology found in our award-winning Black Quantum Fuses, including UEF Graphene Shielding, UEF Black power cords enable your system to recreate music that is amazingly free of distortion for unparalleled musical realism. In fact, even modest electronics sound like they cost a fortune when powered by Black UEF power cords or better yet, when Black power cords are combined with Synergistic Research Black fuses. But don’t just take our word for it, audition a Black UEF power cord for 30-days in your system risk-free or your money back!
