Found a good Youtube video describing the Raspberry Pi. I do have a spare PC that just got replaced by a new one I could probably convert to a dedicated music computor. Not sure if I want to spend that much time screwing with it though. https://www.youtube.com/watch?v=DmeUxk14vCc

Found two other options for a music streaming device with internal "audiophile" DAC. Each requires tablet or Ipad type interface.

Bluesound Node 2: http://www.bluesound.com/en-us/products/node-2/

Auralic Aries Mini: http://www.auralic.com/en/

Both of the latter options are appealing to me. Not real sure which would be a better option.....
