Apple TV 4K or S50pro+

Hi guys, I have AppleTV4K connected through HDMi cable to my TV then from my TV with optical cable to my FIIO 007 cheap DAC converter and then it goes as RCA cable to my integrated amp. For music playing
I am using on ATV4K installed Spotify app + Plex app for Flac files which are stored on my NAS. Do I get better sound quality from S50pro+ then from ATV4K? thank you
