I am not looking for wholesale replacement of these speakers and as such sound great to me already. The only change is to balance the rear surrounds better with the major changes I made with the fronts. The MiniMonitors are my left and right surrounds and are great for my needs. Given this, what AVR would you suggest and please give me a why you choose that particular AVR.
Since your budget is $3K and is stretchable, you are going to have some good choices such as the following:
a) Marantz SR8015 but since the HDMI2.1/8K Panasonic issue bothers you, this choice would depend on whether Marantz could fix it without a hardware change.
Apparently they suggested some sort of work around while still working on solutions.
b) Denon AVR-X8500H (the upcoming new eversion), this would depend on whether the new version will have addressed the Panasonic chip issue, it is more likely than the SR8015 obviously because they can still fix it before launch.
c) 2021 Yamaha replacement of the 3080, in case you change your mind on YPAO (is that really a show stopper for you?)
The Yamaha RX-A3090 would have been a great choice but you don't seem to want YPAO.
I am not against Anthem, in fact I like their integrated amps and power amps, just don't believe they, as well as Arcam, NAD can do as good a job on AVRs and AV preamp processors. So I can't recommend theirs until I see improvements reflected, verified by bench measurements. Subjective reviews alone won't cut it for me.
In my opinion, AVRs/AVPs are much more complicated AV products that are better done in the hands of the big dogs who have unlimited engineering resources, relative to that of the smaller companies. If you frequent various forums such as AVF, AVSF, ASR, HTHF etc., you would see a more issues/bugs brought up on those products than Yamaha, D+M, or even Onkyo and Sony. That, combine with their much poorer measured results (that may nor may not result in audibly worse "sound quality" depending on other factors), I would not go for theirs because I would not pay more for less. Again, I don't put any value on subjective claims on forums about their so called/claimed better "sound quality". If an AVR have higher distortions at both low output and rated output levels, they can't sound better than D+M, Yamaha's that have much lower distortions measured on multiple benches. To claim otherwise would simply defy science and logic.
For Room EQ, if you are interested you can visit a couple of threads on Audyssey and the Editor App to see how a few of us were able to achieve +/- 1.5 to 3 dB in the important 20-120 Hz range and with good result in impulse response etc. too. As long as you use the App to fine tune things, I doubt Anthem's ARC can do any better, if not worse.
The AVR-X8500H clearly would cost more, and only if the upcoming updated version satisfy your requirement in terms of the Panasonic chip issue. On the objective side it is still the king on the ASR bench, for subjective review, you can refer to Audioholics.com's (got 100% 5 stars!!), and/or ask
@DJ7675 who replaced his Dirac Live equipped NADT758 V3 with the X8500H.
