So - I've had this installed a little over 24 hours and haven't really sat down to listen as much as I would like but have played some of my go to titles as well as the Demo Atmos disc that comes with it.
Here are some of my initial feedback:
Surround effects are amazing
Subs are impressive
Center channel is also very impressive, dialogue does not get lost
It's a good looking bar
Remote works well (based on the previous model having issues)
HDMI switching seems to take forever, that is changing from one input to the next
No wired or wireless networking
Weird handshake issue with my Shield from time to time
Sub volume is just to reduce the volume of them - not the overall effect
Overall I'm pretty impressed, separation is great and it truly does sound like a 9.2.4 system, even my 14 year old was impressed and just sat there saying 'WOW' (quite a reaction from a teenager). The subs are impressive and pack a lot of punch, but weirdly they sometimes seem absent, it would be great to be able to set a cross-over setting below 110Hz
Now for the comparison to my Samsung Q90R - The Nakamichi definitely wins on the overall surround soundstage, no question. But for me, the Samsung just seems to have a 'warmer' sound - the Nakamichi sounds a bit less warm and sounds like there's too much treble, especially on the center channel. When the subs are in play with the Nakamichi it sounds great, but the Samsung one seems to be more of a constant, which i think adds to that 'warmer' sound.
My ideal setup would be to have the Samsung bar and then the Nakamichi rears so that i would be a 9.1.4 system.
I'm not saying it's bad, it absolutely isn't - it's an incredibly impressive system, but for me, the Samsung just sounds better and more in-line with what i like.
I'm also aware that I've had my Samsung for over 6 months and it's broken in - I'm hoping that the Nakamichi becomes a little less 'harsh' when broken in, hopefully on the center channel.
*EDIT* - just played the opening to Blade Runner 2049 - Amazing, jaw dropping sound, not regretting this purchase at all
