Synergistic Research Atmosphere SX Ethernet Cable We designed and voiced Atmosphere X Ethernet to convey music with a unique emotional connection that will have you listening for hours as you experience music with startling holographic realism and detail. To this end, we use our propriety UEF Graphene Shielding for the lowest noise floor possible and a new conditioning process first developed for our Blue Fuses. A new testing procedure allows us to achieve a unique degree of musical purity along with all the traits Synergistic Research is famous for like a low noise floor, high resolution, and holographic realism.
