I am with @ghdprentice on this one. The MA3 is decent enough but still requires you to source an external device to run ROON core. Which is another whole bag of tricks you need to put together in order to take full advantage of MA3.
Before you finalize your DAC purchase, narrow down your options for streamer or server. These two components must take full advantage of tech on board (USB or SPDIF connectivity) and superiority of Internal clocks in either DAC or Streamer.
And lastly, based on the quality of your streamer/server; network optimization would be the next step to fully realize the potential of digital streaming.
