I have offered the SqueezeBox 3 Enthusiast Digital Only mod for some time.
This mod separates the noisy, internal switching power supply from the clock and runs it external.
Until now, the only way I offered to power the mod was a modded ELPAC WM220.
I have finally completed work on the Splitter Power Supply

You can plug any 5 volt power supply into this box and it will output the original 5 volt AND a very clean, regulated 3.3 volts.
With the Enthusiast digital mod, this Splitter and the power supply of your choice, your SB3 will be able to output a much cleaner digital signal to your DAC.
The Splitter Power Supply can be ordered
here for $150.00
