Apple TV Streaming Sound Quality vs Streamer?

I am looking for the weak link to improve sound quality.   Seems logical it is the Apple TV as a source.  Would a moderate streamer inside of $1500 make much of a difference when streaming Tidal and the like?  

Current Equipment:
Speaker: Dali Euphonia MS-4
AMP: Modwright KWA 150 SE
Preamp/ DAC: Peachtree Grand Integrated
Source: Tidal / Apple TV
AppleTV resampling to 48k makes highs sound tizzy. It doesn’t sound good. Do yourself a favor and get a decent streamer, like a Blusound Node 2/2i as others have suggested. If you’re going to use an external DAC and don’t need the enhanced wifi of the 2i, save a few bucks and get the Node 2. Node 2i DAC section sounds better than the older Node 2, and the wifi is faster.

I'm using ethernet connect my Node 2, and also using an external DAC so only need the streaming features. Don't need the enhanced wifi and don't plan on using the internal DAC so I went with the older Node 2 and saved $175.
Does anyone know if the node2i will bypass it’s own dac and serve to my Benchmark dac?
Supposedly the main change in the Node2i vs the N2 is enhanced WiFi.  It should still have the same digital outs and therefore connect to any DAC
"Does anyone know if the node2i will bypass it’s own dac and serve to my Benchmark dac?"

Yes, except you'll not get the MQA treatment through Benchmark. 
There are some streamer products in the $700-$800 range such as cocktail, marantz, Cambridge and others that offer additional functionality etc.  Are these good options in terms of comparable sound quality as the node? Any in particular as you go up the price scale slightly?
