Out of them, RSX BEYOND Phono Cables are among the best known to designer Roger Skoff, they are likely to be the best sound Cables, considering theories and limitations of today's materials technologies and, in the absence of major new discoveries, they may remain the standard for judging all other sound Cables out in the years to come.

Connectors designed by Roger Skoff have been added with a smaller contact mass (to minimize self-induction) and use a more advanced Teflon®- variant fluoropremer - air dielectric material, with an improved fluoropremer housing added to reduce capacitive discharge effects.
