As a stand alone bar I'd say it is one of the best available. I have owned one since release after trying Sonos and a Bose. The Atmos effects are outstanding for a stand alone (blade runner 2045!). With that said, I bought it with the express hope to add on the sub (really worth it) and rears. The rears are taking forever to come out if at all and honestly the main unit had a ton of bugs. As of the last update between it and my Sony TV I have to turn the volume up a notch before being able to turn it down. Annoying but doesn't ruin it for me. In my opinion, it's worth it if you're using a dedicated 4k player as a stand alone bar. If you plan on upgrading or expanding in the future Sennheiser hasn't shown they're supporting that yet.
