I still am using the RasPi/DigiOne SPDIF feed in the Schitt Gungnir MB, but I have to give a tip of the cap to Scott McGowan's Sprout100, and its DAC stage, from USB, or Toslink input. Sometimes it is just so convenient to flip the knob from ANALOG to DIGITAL to hear the audio on a video. And I run the RasPi on the big screen TV while the monitor on the server is a direct feed by USB. It sounds really good. (And through headphones, also.)
Is the Raspberry Pi with Allo DigiOne the Ideal SPDIF transport?
I am convinced the ideal endpoint for a home LAN Music Network is the Raspberry Pi with the Allo DigiOne SPDIF Transport, powered by the iFi Audio iPower 5v PSU.
