Channel Islands Audio (CIAudio) is now shipping for the Logitech Squeezebox Duet, an alternative power supply to the Logitech's one. Called the VDC 9.0, this upgrade is said to eliminate noise caused by the standard switching supply, which can contaminate the internal digital and analog circuits. The power supply unit provides an output voltage of 9V DC rated at 2.5 Amps, the design is based around a low noise/high current transformer, discrete Schottky diode bridge rectifier, AC line filter, precision voltage regulator circuit, and 13,600uF of filter capacitance.

The PSU is available in 120 or 240v input for $279.00.
