Need DAC/Streaming Advice


I currently own a Bryston BDP-2 digital player that I run through a Bryston DAC.  As far as playing high resolution files via a thumb drive or other external drive, the BDP-2 sounds great.  The streaming part leaves a lot to be desired.  I can stream Tidal but it is extremely slow and the IPad controller is pretty lousy.  I can listen to Sonos through the DAC into my main system but obviously there is no hi-Rez via Sonos. I would like to find a better solution and am willing to start over (I can move the Bryston components to my secondary system).  What I would like to find is a higher end streamer for my main system that would allow me to stream Tidal, Spotify and Deezer if possible while also playing digital files via thumb drive etc. I have no idea if that can be done in a one box solution or if I would need a separate streamer and DAC.  I would very much appreciate any and all thoughts.  Thanks in advance.

I'm taking a hard look at the Lumin U1 mini.  No internal DAC (which is what I want)  but I'm not sure I have the infrastructure to run it.  
I just wish I could find something under $1500.  MSRP for the Lumin is $2000.
The BDP-2 should be a nice streamer. It should be more than quick enough. I would try different sofware before buying an other streamer. 
Serious music server software on a NAS might do the trick. I'm using Minimstreamer. It's very responsive. Other player software might be it. Like Bubbleupnp on an Android Phone. I'm using Bubbleupnp with Tidal/Qobuz for 3 years now. It always has been immediate in its response.
Well with regards to Roon with the BDP-1 there is an option on the services area of the Bryston interface (Maniac Moose, not the Bipolar Bison :) which allows you to enable ROON option, if it does not show up try running a firmware update. Once this options is enabled then ROON will be available. Hope this helps.

sorry to hear about your Bluesound problems.  Did you try a different streamer?
I have the node and the main problem I have had is that it has a very weak wifi receiver. It will miss or drop a signal that my Apple TV or MacBook pick up without a problem. I have tried elevating it on books, tables, etc but the problem persists. But if you use it wired with Ethernet it seems fine. Good sound for its price and the app for me has been fine.
