UltravioletTM 7 USB utilizes the same advanced design as the Starlight® 7, but with less silver to save cost. The cable"s unique flat profile is only 3mm thick, for extreme flexibility and easy concealment. With higher precision and lower loss than conventional round USB cables, UltravioletTM also provides distinct improvements in sound quality and the ability to function well in lengths of up to 7 meters (23 feet), making it possible to connect a laptop PC to a home theater system across the room.
