This is the chunkier version of The Mainserver AC cord from Van Den Hul. The Mainserver was designed for light current components like source units and preamps. The Mainstream on the other hand is designed for high current components like amps or power conditioners. So if you want to upgrade your stock AC cords of your amps or power conditioners, this is an affordable upgrade.
The cable was previously used as a store demo so some light scuff marks are present but nothing major. Cable will be securely packed for safe shipping.
