Just my 2 cents, all of the RPi based streaming distros kind of suck. Better off with a commercial streamer (Wiim, AppleTV, etc) and a vanilla RPi distro (Raspberry Pi Lite, Ubuntu Server) running CamillaDSP connected to your DAC. Even better if your DAC is an audio interface or something like the Okto that can act as both a capture and playback device on CamillaDSP, although a cheap TOSLINK to USB device can be used as a capture device if needed.
Commercial streamers are more polished and stable and with a stand-alone CamillaDSP implementation you have complete control over CamillaDSP.
