Hi folks, I have the Heos Bar for almost a month now and ended up getting the subwoofer and 2 Heos 1 as surround. Must say I'm pretty disappointed with the overall ecosystem, specially since the app is extremely buggy and inconsistent, and I'm also experiencing dropouts with the wireless speakers (both surrounds and subwoofer).
The bar decodes pretty much anything, which is great in that sense (except Atmos or DTS-X), but it has a clunky interface to switch inputs (no remote control, so you have to either map a bogus one manually or switch through the app only).
Overall movie playback is pretty good, although I do hear some reverberation in vocal tracks, specially in lower frequency ones. Not sure if I have an issue with my specific bar or it's overall.
In terms of music, it seems like the Heos 1 in stereo play better than the bar itself! The subwoofer integration doesn't help much imo as well.
The dropouts are the biggest deal breaker for me right now so I'm seriously considering returning it if I cannot get it resolved with the Denon support team. Let me know if you have any specific questions that I could answer.
