Yamaha RX-V4..any experience?

My Onkyo TX NR818 has finally succumbed to the nasty HDMI board failure...and so it is time to replace her. The new Yamaha RX-V4 is on my radar, anyone have any experience with this new Yamaha HT receiver? I know the V4 is only a 5.2 piece and does not support Dolby Atmos, but since I only have a 5.1 system, i am not that concerned about this.
OTOH, the new Yamaha does support 8K pass through and has all HDMI 2.1 inputs! Thoughts?
I worked for Magnolia for a bit and got to compare the top Marantz, Denon, Arcam, and Yamaha (previous generation) AVRs directly using B&W 804D3s and my best stereo demo recordings.  I was surprised, but the Yamaha was the best of the bunch — most transparent and with the best imaging/soundstage abilities that reminded me most of good separate components.  Haven’t heard the newest Yammy AVRs, but I’d tend to think they’d make the new ones at least as good if not better than the previous models.  Another plus is that Yamaha AVRs tend to be more reliable than pretty much all the others, at least from what I’ve seen and heard.  Anyway, FWIW and best of luck.  
Thanks. I will be using the B&W 686's for the front channels, so i guess they should be ok with the Yammy power of 80watts/ch.

The "RX-V" series is the low end series of Yamaha AVRs.  Also, it's my opinion that this whole thing with 8K is silly.  The current 4K with HDR standard is more than you will ever need at this point. 

The RX-V4 is actually a very light receiver at just over 19 lbs.  If it were me, I would look for a receiver more in the 30-35 lbs weight range.  This points to a bigger main power supply (transformer and capacitor bank).

For sound quality, I think you would be better off getting a previous generation Yamaha receiver at a higher level.
@auxinput   I currently own a receiver like you describe. The main power supply is certainly quite beefy, BUT the problem is that the various caps are placed without concern as to their heat propagation, which is what I find common on a lot of this gear. As such, the failure rate is pretty high. In the old days, weight used to be a factor as to the ability, and sometimes quality, of the unit, i don't think this necessarily applies today. 
My current receiver cannot pass through 4K, which when I bought it was no issue, now it is...I like the idea of a little bit of future proofing, hence the appeal of 8k pass through.
