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.

You’re very good with an investment in Bluesound. Reliable and nice app. Bought a cheap iEast streamer recently. Don’t know how it works yet. Auralic mini another example. You can input a harddrive with your own files. Don’t know their app. Oppo Sonica, Simaudio Moon, naim... Lot’s of competition today. Not necessary to pay big money for just the streaming. Maybe for other special functionality you like to have. Most often the apps are the problem. Especially careful with "non-entry level" brands.
Just installed Bluesound node2i and have not been impressed when comparing the sound to CD.
Have only had in system for 2weeks but from my iPad with Tidal so far no issues of locking or freezing.

Should my Yamaha 8801 integrated internalDAC improve  the sound quality?

The Bluenode 2i with a good dac plays way above its price. It is not entry level at all paired with a good dac. I use mine with a Benchmark Dac 2 into Ayre preamp and Mark Levinson amp and it sounds great.  My Levinson dealer sells quite a few high end lines and raves about the Bluesound. Benchmarks are great for making even CD or Redbook quality sound excellent,  though you wont get full MQA with this setup , only 24/96 when streaming Tidal MQA. 
Look at the Zen Mini MK3  High quality server with built in DAC (or can connect to any DAC)  Can import all your music, built in CD burner.  A very easy interface with iPang on your iPhone/iPad.  An optional linear power source available.   Spotify, TIDAL, and Qobuz, and Internet radio ready. $1250 ($1900 with PSU) with 1 TB storage.  Up to 8 TB available.
I am not a dealer or have financial interest, just a happy owner.  
Check out Antipodes Audio from New Zealand. Their streamer/servers are world class. The onboard DACs are more than OK or you can use an outboard DAC if you like. If you're in the US, your dollar conversion rate will make them even more attractive
