OP, what’s your budget? I also have a Node2 and like it a lot but there are better streamer/DAC combinations out there. You can even start with a $35 Chromecast Audio and use optical link into your existing DAC and see how you like it. As for 24 vs. 32 bits or 96 vs. 192k, by far majority of the best MQA encoded content from Tidal is at 96 so your DAC’s optical input will suffice.
Digital streaming options for my system are confusing
I appreciate your advise in advance as I am more of a old school vinyl/cd guy. I have a McIntosh MAC6700 integrated receiver. It has a DAC but tech in this area is evolving at such a rapid rate that I am confused as the best way to access a high audio quality streaming/digital playback source. I have heard hi end streaming services (Tidal?) are great but my Amp does not have a direct iPhone/iPad connector. What is the best way to go that will keep my system simple and easy for the whole family to access?
