The regular power cords that come with your gear are made with mediocre materials, from conductors to connectors, and lack proper shielding against radio frequency interference (RFI) and electromagnetic interference (EMI). Both RFI and EMI add unwanted noise and distortion to your sensitive audio gear. These high-end power cables are designed to deliver the high-current your equipment needs with secure connections, and provide superior shielding. While high-end power cables won't magically filter out signal distortions, they do an excellent job of preventing the cable itself from collecting unwanted distortions and mixing them with your power.
This selection includes power cables with premium 15 amp-rated NEMA AC and IEC connectors, plus a few with 20-amp connectors for special power amps.
