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
Hello and thank you for all your feedback on this topic. :).
In keeping it simple, does anyone has any recommendation on a simple cable that can be purchased to hook up the ATV4 via HDMI out to my Canary KD2000  Dac, preferably USB as it supports all music files, as well as  DSD64 and 128....
If USB is not an option, AES/XLR or Coax works just as well. I think....

It doesn’t take much to better ATV sonically, and you don’t need to spend more than $500, the price of the Bluesound Node2i
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
