ECS Core Audio Interconnect Cables begin with small diameter OFC copper conductors with polyethylene dielectrics constructed in a tight twisted-pair arrangement for optimum noise rejection and encased in a translucent, small-diameter PVC jacket. Machined, nickel-plated, brass contacts offer superb connection integrity. Molded connector bodies feature an all new design with soft grips and are short by design to facilitate installation in tight spaces. Flexible silicone channel splitters make them easy to run through tight openings.
