Thank You everyone for your ideas.
Looks like these are the single box options I've seen on top 10 lists out there for a 7.2.4 setup (which i have already wired into completed theater walls):
Denon AVR-X6400H 11.2-Ch $1,499 on Amazon...says "discontinued by manufacturer". Is that a killing point to consider it like they won't do warranty work?
Denon AVR-X6500H 11.2-Ch $2,199 on Amazon
-RZ5100 THX-Certified 11.2-Ch $1,299 on Amazon...called a "Pre-Amplifier" not receiver but says it can do my setup
Onkyo TX-RZ3100 THX-Certified 11.2-Ch $2,137 on Amazon..has a 'con' of low power-140 W/Ch (8 Ohms, 1 kHz, 0.08% THD, 2 Channels Driven). Power is quoted at only 1 kHz, rather than the usual 20 Hz–20 kHz
Pioneer SC-LX901 Elite 11.2-Ch AV Receiver $1,682.49 on Amazon...has a 'con' of No Hybrid Log-Gamma (HLG) pass-through
Onkyos have THX certification plus Wi-Fi, AirPlay, Bluetooth and Chromecast.
Denons have Alexa, echos, etc
Was going to use my Onkyo for 7.2 and not using the height speakers til the $2k prices come down for a single solution. But now seeing the 5100 above for $1,299, Denon for $1,499, and Pioneer for $1,683 more enticing to perhaps pop for one. Are these old and inferior to the ones at the $2k price point?
