When you sit down to listen to your sound system, you want to feel the emotion of your music and enjoy the sum of everything you’ve invested. Atmosphere Level 4 Speaker Cables with 4x Pure Silver Air Strings provide you layers of refined detail, while 2x Tricon cable geometries increase holographic sound-staging to immerse you in the music. Beautifully handcrafted and individually sheathed for superior vibrational isolation and flexibility these cables exhibit extraordinary levels of refinement and dynamics. All Atmosphere cable technologies are present in Level 4 including the more complex Type 2 UEF Graphene Inductive Cell to filter signal outside-the-signal-path inductively with UEF Technology and Graphene for near super conductor performance. Eight geometries in parallel individually UEF and Graphene Shielded connect to an SR Ground Block compatible UEF Ground Plane for music that emerges from a black silent background. System matching is also state-of-the-art with both the RED UEF Tuning Module for warmth and bloom and a BLUE UEF Tuning Module for air and fine detail. In systems combining both Level 4 interconnects and speaker cables you can mix and match BLUE and RED UEF Tuning Modules for a custom system match that takes the best from both filters to compliment your unique system.
