Streamer Value Question Innous vs Bluesound

OP

if you hardly have any CDs and downloads and don’t intend to add more then you don’t need to spend for a streamer that has storage and ripping functions.  Just make sure that is has a slot for thumb drive.  So I wouldn’t get the Vault2 as you won’t need 2/3 of what it does.  If you decide on Bluesound just get the Node.
  I upgraded from Bluesound to a Bryston BDP3.  Qobuz sounds much better on the Bryston, but the Bryston BDP3 costs a lot more than the the Bluesound.
  I couldn’t get Qobuz to work at first on the Bryston.  It did work on Bluesound and my Android phone.  Bryston’s CS fixed it remotely, but whatever streaming service you choose you may want to try try it first from a phone or PC.  Then once you are comfortable with how it works, if there are any issues with the service playing on the streamer, it may help you decide who is at fault, the streamer or the service.  That can be helpful because as with any IT software/hardware compatibility issue, the two companies tend to point fingers at each other

I recently upgraded from a Node 2 (not 2i) to a Mytek Manhattan with network card. I originally did not plan to get the network card (streamer) but it was being offered for free with the DAC and I am glad that I got it. I have direct compared the Node playing through the DAC on the Manhattan and the Manhattan using its internal streamer and the internal Card is a better. However, the biggest jump in quality came from getting the better DAC- I’d put the improvement split at 90% DAC and 10% streamer in this particular case. Not sure what your budget is - the Manhattan is in the >$5K range but they also have a Brooklyn model that I think is under $2K. 
I bought mine direct from Mytek. Michael, who is the designer of the equipment answers all of my emails - usually within minutes. Excellent customer service. 

I am really happy with my purchase. The improvement in SQ is night and day, not small. As always YMMV. 

I’ve had a Bluesound Node 2i and found it extremely buggy with no tech support.
Node did work for few months then just crapped out. It mostly didn’t work as it was intended, it wouldn’t recognize my Eero Mesh network even though it was directly plugged in. Reset the device and still no joy. I’ve returned to my HiFi dealer after 5 months, and now picking up an Innuos Zen mini.

I would add the TEAC NT-505 to your list.  You won't have to (and can't) use an external DAC.  It comes with a very good DAC, does MQA, Roon, all that good stuff.

Don’t want to sound like a broken record (pun almost intended relative to this general forum!) but why not consider the surprisingly good RPi based Allo Digione (or Digione Signature)? It can stream most everything mentioned here, can be easily equipped with a LPS, and had been (considered) to outperform the bluesound nodes in at least a couple of reviews. Well, I think Darko still makes that assertion, at least. With every new DAC upgrade I’ve made, it just keeps surprising me. It would take a big budget jump from this particular RPi platform before overtaking it.
Otherwise, SOtM then Lumin stuff seem to be really great for the $$$.
