Edwards Audio PSU1 Power Supply 

The PSU1 outboard DC power supply is designed to be used as a simple plug-and-play upgrade to the performance of Edwards Audio's MM1, MC1, HA1 and other future products. Based around a custom wound 30VA toroidal transformer, the design features split rail topology with EA's advanced regulated design techniques to reduce all forms of noise while maintaining a fast transient capability. When upgrading from the plug top PSU supplied with the MM1 or MC1 it is a simple matter of plug-and-play using the supplied leads. The improvement in sound quality is both immediate, obvious and dramatic giving much more authority, smoothness and openness to the sound.

The PSU1 is unique at the price, with its fully RoHs compliant gold plated custom made double sided PCBs, natural anodized extruded aluminum case and high quality internal parts. It also benefits from 1% thin film SMT Mini melf resistors plus low impedance electrolytic capacitors throughout.
