Wireworld Aurora 7 Power Cord By adding silver to the Stratus 7 design, Aurora 7 provides greater refinement in tone color and imaging precision. Aurora 7 is a flexible power cord that can enhance the performance of mid-range AV systems. This high-end power cord is ultra quiet and dynamic. Flexible flat design bends and coils easily. The standard cable includes Globe-Grip plugs on AC, and 15-Amp IEC ends. Since Wireworld power cords function as filters, longer lengths improve performance.
