Studio ONE replaces the discontinued Au24 SE cable line. The wires are mostly engineered in the same geometry as the Au24 SE they replace. Significant improvements in Studio ONE include 1) an improved XLPE dielectric vs. Au24 SE, and 2) treatment with our proprietary EHVP (extreme high voltage process). The result is that Studio ONE is a better-sounding product than its Au24 SE predecessor at the same price level. Studio ONE also includes phono and headphone cables.
