Thanks, that was my thoughts. Although I have perhaps moved on to something like this as my main concept:   http://www.instructables.com/id/Wall-Mounted-SqueezePlayer-with-Raspberry-Pi/?ALLSTEPS   With one of the hifi raspberry pi addon boards for the output.

Hi, I am late to the party on this one, but have a question.   It seems you end up with two devices, the MK808|DAC combo to play the music, and the Nook to act as a controller.   Can you think of any reason why you can't run the whole lot on a tablet that had a USB host or OTG port to plug...
