I have the node 2i, the internal DAC is pretty rank, so I ran it through my OPPO 105, huge improvement - I was pretty happy with that. I just got the Black Ice (Jolida) it is on sale right now for $679, it has only been running two hours - so I am going to withhold any judgement on it.
I think as a streamer - the node 2i is pretty good. The software is not too bad also - not too good - but not too bad. Someone else had mentioned Chromecast - I tried both the audio and HDMI versions - it's ok, but not like the bluesound. Plus I was plagued with connection issues on it.
I stream Qobuz in high res primarily.
