I bought the soundbar from Video & Audio Center via Amazon marketplace. I was a little skeptical since it had not yet officially been released; however, they are an authorized Samsung dealer, so I made the purchase and everything arrived promptly, unopened and successfully registered with Samsung recognizing the manufacturer 1-year warranty!My initial impressions are vague since we cannot yet play any Dolby Atmos movies - however I can report my Apple TV 4K plugged into the soundbar, then the arc ports of the soundbar and OLED65E6P TV connected does indeed pass Dolby Vision (however, there is a lag between the audio and video when watching as Dolby Vision). The soundbar has a Sync feature which allows you to delay audio which does help. I even bought the Belkin Ultra High Speed 48gbps HDMI cables; however, this has not helped.When using with a Logitech universal remote - it surprises me a $1700 sound bar does not accept a IR signal to take you directly to the appropriate input, instead you have a source button you have to toggle through the inputs... This leads to issues since the soundbar does auto detect and tries to place you on the input which can conflict if the remote also is changing inputs; however if the AppleTV is on and you are switching to (i.e. a PS3) I always land on the wrong input even with the remote set to not send a change in inputs... It's very frustrating! Especially when you have non-technical household members :).My favorite thing about this soundbar is the side-firing effect... that really stands out! I have the sides open and there are walls on either side. As for the overhead - both the forward and rear overhead are hardly noticeable in the simulated surround mode... The ceiling is 7 1/2 feet and the soundbar is 2 1/2 feet high and 9 feet away...Edit - 9/4, I finally had an opportunity to see the "Dolby Atmos" / "DTS:X" scroll on the soundbar's display by playing various trailers (like Dolby's Amaze) through my Microsoft Surface - really great quality! The rear speakers really standout during these soundtracks.I switched to "Standard" rather then the "Surround" mode for non-Dolby Atmos/non-DTS:X because in simulated surround the rear speakers seem to be more of a whisper... I would like to get rear speaker stands to bring them closer to ear level.After this and other tweaks (Side +3/Front Top +5/Rear Top +5 and Rear +4), I am much happier with the quality of the audio. Music sounds amazing, bass is really impressive and the vocal clarity is much better than my ancient Sony receiver with 7.1 Bose speakers I had in place before.Setup was easy; however, just power them on, for the first time, in the order the instructions say (Subwoofer, surround and then finally the soundbar.) All the pieces connected without any issues and the rear speakers have stayed connected. I wish some type of demo mode or sound setup was included to highlight the features.I added the skill to my Amazon Echo, but I haven't yet found it to be useful; however, it is a nice feature. SmartThings WiFi setup was a breeze, but the included options in the app are rather limited. But overall, I am indeed much happier then my initial review may have suggested.
