I guess most people have mediocre sound bar playback audio for home theater, and I understand they could care less, or are unaware of better sound quality.
Most Blu-ray audio is high rez ( better than CD quality).
And DVD audio quality can be CD quality.
When will steaming services realize that some home theater systems have expensive sound playback?
I feel that there is still a need for physical disc play back in home theater if you care about sound quality.
Some steaming sites like Tidal, Berlin Philharmonic, Met Opera, Radio Paradise,Vimeo, and others have at least CD quality playback.
