Headphoneus Supremus
I second that,
I'm currently using a Raspberey Pi, along with a HiFiBerry optical and Coax add-on board - running JRiver MC 21 and it sounds brilliant.
I also got a custom linear PSU for the Pi (from Tomanek ($100) - made a nice improvement and added a power button
All is feeding the Yggya and works great.
The only issue with the Pi is that you have to be a little technical and work a bit with a headless Linux box.
A CuBox-i from SolidRun with Volumio is very easy to set up and control, no cut-and-paste of mysterious shell commands needed.
