If the Apple TV 4K and Nad M17 both have eARC, streaming should not be compressed. You need to assure both have eARC. After the processor it's analog. Of course audio quality is dependent on the source, be it vinyl, disc, or streamed.
TV audio into DAC via eARC or better
My HiFi system is also in my main living room which has my largest TV for movies. Currently running optical audio out of my Sony TV into my Schiit Yggy. It's ok but something is missing for sure. Xfinity 4K box is HDMI only. Apple TV is HDMI only. I would think the highest possibly resolution would involve eARC.
I noticed the Lumin P1 has an eARC HDMI port. Looks like it can also switch video sources but my preference is to keep video quality going straight to the TV.
I know my compressed version of Batman on Netflix from my Xfinity box isn't going to be great but I need something better!
Thoughts? Thank you!

@lalitk No need for Atmos. Toslink is pretty old technology I assume ARC and eARC can send even 2 channel stereo pcm at a higher bit rate to the dac. eARC has a bandwidth of 37Mbps where toslink is only 384kbps https://www.avaccess.com/blogs/guides/difference-between-hdmi-arc-and-earc/

I believe all streaming services including Netflix involve compressed audio. It’s my understanding that the full advantage of EARC cannot be obtained via streaming. As others have said, I use optical out from my Sony oled to my Benchmark DAC1 for my 2 channel bedroom/tv system and am amazed by the sound. BTW, Netflix allows you to change the sound from 5.1 to 2 channel so the digital output from the Sony tv is not doing the 2 channel downmix and the sound is indeed improved.

@chauncey Another option is the Wyred4Sound Remedy Reclocker, it takes the Toslink in and cleans it up and outputs a SPDIF signal, I get a nice uptick in sound quality compared to Toslink into my Bricasti M3. https://wyred4sound.com/collections/digital-converters/products/remedy-reclocker |
