I managed after some trouble to put together this network streamer with the highly acclaimed audiophonics v3 dac and a raspberry pi. It sounds awesome, but it's time for new projects. I am offering it up for sale at 325$ plus shipping. Best of all it powers the raspberry pi using its own linear regulated power supply - el cheapo wall wart gets you 90% of the way. Use 6-7 volts. Using a linear power supply is not going to cause much of a difference.

The setup includes a 32gb sd card which is already Roon/Squeezebox Server ready. Just plug an Ethernet cable and you are good to go. No programming, no fiddling required.
