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.

@mzkmxcv,

You seem like one track pony. Haven’t you done enough trolling here about jitter?

The OP expresses his desire to explore streamer that offers faster and better app interface along with high resolution files accessibility (which your ears can’t tell the difference). 

As good as Bluesound Node is, it remains an entry level gear.

Please explain how it’s entry level in regards to performance. OP has an iPad, so no even need to use the app if you don’t wish to, use AirPlay.
I am probably looking for something better than entry level but given my experiences with the Bryston digital player I am a little gun shy about spending too much money. 
@puppyt,

Unless you try, you won’t know. Most Aurender and Bluesound online retailers offers 30 days return policy.
