Could owners of the Integra, pioneer or onkyo check if it has some options like Audessy Dynamic EQ? And if so it is as good as Dynamic EQ
Thinking of upgrading to 1 of these receivers, but will surely miss Dynamic EQ coming from a Marantz for low level music listening.
I thought it did have a true equivalent, but on further investigation (after someone pointed out that the features are dialogue rather than loudness oriented!), I was wrong...
If you run without Dirac or AccuEQ, you can use THX mode, which has a "Loudness" feature, as detailed on the THX website, this is a fletcher-munson style loudness frequency profile adjustment (same as DynEQ).
If you do use Dirac/AccuEQ (and that is one of the main reasons for purchasing one of these) - then, if you opt to use the Dolby Surround mixer, (which can process streams that originate as DTS, Dolby, or PCM...) - you can enable a "Loudness" mode.
However, according to the Dolby descriptions of "Loudness" - these are not designed to tune the frequency response based on average loudness (with reference to reference level) - but rather designed to optimise the dialogue frequencies for optimal intelligibility - so it is doing something completely different.
Do I know this definitely - No.... I have not been able to find an actual formal description of the Dolby Surround Loudness feature by Dolby...
However Loudness (and what the term means to Dolby) is described here:
Guide to loudness concepts for LUFS and LKFS used in media standards and dplatforms such as ITU-1770, Apple, Facebook, Spotify, SoundCloud, Vimeo, YouTube, etc.
docs.dolby.io
In past versions of the Dolby decoders, Dolby used to have fletcher munson type features - but I don't think that is the case now.
Having said that...
In the belief that "Loudness" meant what it has meant since the mid 1980's I used that as my default go to, given I listen below reference levels.
Compared to DynEQ, I found it disappointing.
The current Dolby Loudness feature does do a great job (in conjunction with Late night mode) for watching TV/Movies at night and maintaining dialogue intelligibility, where it doesn't do a great job, is with music....
Traditional Fletcher-Munson loudness curves (or ISO226...
https://en.wikipedia.org/wiki/Equal-loudness_contour ) do a good job of rendering music at different listening levels - Dialogue processing approaches don't.
So, the answer is a partial yes - these AVR's do a good job for TV/Movies watched late at night when you don't want to disturb the family.... and no, they don't do a great job with music under similarly volume limited conditions. (better to use headphones?)
Having learnt this myself, and although I am a long term fan of Onkyo, I am looking once more at the D&M family - but I really want Dirac ART capability alongside a true Fletcher-Munson Loudness feature - and with the D&M products, DynEQ is only available when using Audyssey, you cannot overlay it over Dirac ART (sadly!).
At present the only device that appears to provide the desired mix of Dirac & Loudness is the Monoprice HTP-1 AVP, I don't know of any AVR's that currently have this capability.
