Great Qobuz streamer. Upgrade from Bluesound Node 2

How about keep the Node and spend on a good DAC?

I use a Bryston BCD3, just a bit outside your price range.  They just added Qobuz The software program for the Bryston, Manic Moose, is a mess.  It doesn’t navigate Qobuz, or anything else for that matter, very well.  I also have to say that when I compare the Bryston to my Bluesound Node2, the Bryston is a significant upgrade while listening to CDS that have been burned to my NAS.  Qobuz also sounds better on the Bryston, but the gap between it and the Bluesound isn’t quite as apparent (but it’s there). Ymmv, perhaps depending upon your bandwidth, how you connect, etc.  Qobuz isn’t my primary source, and given the frustrations of dealing with Manic Moose, lately I’ve just been listening to it with Bluesound.

Take a look at Aurender N100H or C.

I have been a Roon user for a few years and my last upgrade was to purchase a Roon Nucleus Plus, which I highly recommend.  They also sell a Roon Nucleus, but I decided to opt for the Plus model (faster processor, more memory).  The only "downside" is that it only has USB ports; if your DAC sounds its best with the USB input (as mine does), you should be "good", but if you need a coax or optical feed to the DAC, the Roon Nucleus or Nucleus plus would not be an option for you.

If you are good with doing your own installs, you might opt for an Intel NUC and do your own install of the Roon core...a lot less money than the Roon branded NUC.
