One pair of Synergistic Research Atmosphere UEF Level 4 high end audio interconnect cables in a fantastic condition. Higher resolution and more refined, yet remarkably flexible and easier to use. Level 4 has the lowest noise floor for maximum low level information retrieval and are the most holographic of all Atmosphere Series interconnects. Also a first is the Type 2 UEF Inductive Cell which is more complex than that found in Level 3— a Carbon Fiber enclosed filter that strips unwanted noise inductively from the signal path through a complex network of silver and graphene foils similar to those found in our flagship Galileo UEF cables and PowerCell line conditioners. User friendly UEF Tuning Modules including a BLUE UEF Filter that adds an additional dimension of fine inner detail and air over the warmer sounding RED UEF Tuning Module for a bespoke sound you arrive at by simply comparing the included RED and BLUE Modules. The Atmosphere Level 4 Interconnects are built on groundbreaking ideas that perfectly match your music and personal tastes. The length is 1,0 metre and they have the original XLR connectors. The original red and blue tuning modules, ground connector and box are included. Serial number is UEF4ICG0536. Retail price is 3.095 euro. Check our other listings for more interesting items.
