just picked up a Bluesound Node 2i, but not sure if I can connect an external DAC to this since it only has outputs. I imagine that analog out on the DAC to analog out on the streamer won’t work.
You got some bad advice. The Node2i is the source and plugs into the DAC. Use Bluesound S/PDIF coax out or Toslink to the DAC digital input.
Then Dac RCA analogue out to an analogue input on the Hegel amp.
