If anyone is interested in creating a decent sounding, but reasonably priced endpoint, here is my parts list. Still working on making it look pretty, but sounds good! ~150$ a piece including speaker.
PI Model 3 - 39$
X400 (IQaudio clone) - 30$
Power Supply - 8$
Polk Audio RTI A1 Bookshelf Speakers - 150$ pair (warehouse deals) or 75$ each
I am faux bi amping the speakers by mono to the two sets of posts for about 40 watt per speaker. The setup is running raspbian w/ the roon bridge software. I have 4 set up so far and they work pretty flawless, also using them for various linux automation functionality. Sounds good and can fill a room at 30% volume. Two cover about 1k sq ft downstairs.
For local control I have a cheap ($20 on ebay) Amazon fire tablet mounted on top.
