To be fair, I should have elaborated, and congratulated
@hifihillbilly for becoming a proud owner of a very nice AVR first and I hope it is not too late to say this now.
Subjective reviews are subjective, and that's the hearsay I referred to, whereas bench test results and specs are more objective, and if published/measured/tested in honorable ways then they may be more credible.
I fully understand why if one do a search, one would likely find more rave reviews about the more expensive (boutique brand??) AVRs such as Anthem's, NADs, and of course prepros. IMO, that is mostly because subjective reviews are naturally more affected by the list price, i.e. if it costs so much more it must be better otherwise why would anyone make/ buy it etc.etc.? As for users, people who own Anthem MRX, after paying more for less (I mean feature set, bells and whistles),would naturally treasure them more than those who spend $899 or less on an AVR-X4400H or Marantz SR7012 do, hence the nature of those subjective reviews/owners reports etc. that gradually became hearsay kind of "facts"),and I'll just leave it there and move on to specs and bench tests.
Regarding RC/REQ, I have read about how Anthem ARC, Dirac Live could do better than Audyssey and YPAO too, but in my experience, I could dial in my left, right with two subs integrated to within +/- 3 dB easily between 16-120 Hz using XT32. If I work hard with the App, and are willing to spend time fine tuning using the sub's phase and PEQ, I may get it within +/- 1.5 dB, would it make a difference audibly, I would guess not. I also doubt AARC or Dirac Live could make an audible difference, with their reportedly "superior" RCs.
Below is one of my old Audyssey On vs Off graph from 2017, plotted in my HT room, for the front speakers and two different subs, 1/48 smoothing. I was using the Marantz AV8801 at the time. Now, with the X4400H and the Editor App, I could tighten the window by at least another dB easily. If anyone manage to achieve a tighter response for the same range using Dirac or Anthem ARC, please share, it will be much appreciated.

Now if look at the following bench tests, first THD+N vs output power:

That graphs are both THD+N vs output, now take a look at the comparisons in terms of noise and cross talk:
Anthem MRX-1120 ($3,499)
Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –77.12 dB left to right and –77.07 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –109.43 dBrA.
Marantz SR7011 ($2,199)
Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –71.72 dB left to right and –71.55 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –107.82 dBrA.
Denon AVR-X3400H ($999)
Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was
–82.08 dB left to right and –80.79 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –109.98 dBrA.
S&V seems to have stopped bench testing, and I could not find any apples to apples bench test for the equivalent AVR-X6400H so the X3400H will have to do it, albeit at disadvantage in the output power department obviously.
Note that Anthem MRX720 and 1120 (11 amp channels) are rated 140 for 5 channels only, the remaining channels are rated 60 WPC, I don't want to provoke guys like
@TLS Guy who seem to think that we should not short change the surround channel so he if he sees this he may have some to say..
