I too am sticking with the 809. Bought from Amazon for $450. Absolutely gobsmacked by (a) the price, and (b) the audio performance. Stellar sound. I decided to order exchange as the front door wouldn't close properly and I swear I noticed the odd HDMI dropout while watching Netflix - though I wonder if it was my imagination.
The new unit had higher serial #. So keeping the newer one.
Over the past few weeks I've tested almost everything under the sun (or so it seems) including:
Yamaha RX-V671
Yamaha RX-V773
Denon 2112ci
Denon 3312ci
Onkyo TX-NR616
and even the new Harman Kardon AVR 1700 (excellent performer for the price - I tried $169 open box from BB).
In the end, nothing could touch the audio performance of the 809. I'm very picky about audio quality in my home theater and given that I only change out the receiver every 5 years or so I get extra ornery. Maybe a little OCD, lol. I don't know if it's the MultEQ XT (though the Denon had that too) or the amp power, but whatever it is this thing truly shines with movies. Never does it feel as if it's "falling apart" when pushed to high volume. Conversely there's beautiful separation and clean delivery at low volumes too. Also, I found the center channel clear, unlike others that often sounded muddy.
Of course, my honeymoon phase may end quickly if the 809 catches fire like it did for the guy on Amazon (who posted vid).
