If you are planning to use an external DAC, you may also want to take a look at the Chromecast Audio as a streaming option. I was very skeptical at first but for $35 its got a pretty darn good performance. I also have a Bluesound Node2 in a different system and Chromecast when run through Schiit Modi Multibit, comes really close in terms of sound quality. Need a mini-Optical to optical cable to connect to a DAC. No brainer for $35.
