I just upgraded from Beam to Arc and am incredibly happy overall. The wider sound stage alone makes it a worthwhile investment. I’ve got a 65” TV and the stereo separation of the Beam just wasn’t wide enough to support the screen size.
Currently, my TV uses HDMI ARC (no eARC) and will support the Dolby Digital Plus format. That said, I’m not sure if I’m getting the DD+ version of Atmos or not. Checking About My System section and it usually reads Dolby Digital Plus 5.1 for Atmos movies.
Knowing this, is Dolby Digital Plus 5.1 the lossy version of Atmos? The Sonos app doesn’t display the Atmos logo when watching Atmos content, so I’m not sure exactly what audio format I’m getting.
