What room correction systems includes or works together with loudness compensation for stereo setup?

Hello!

What room correction systems includes loudness compensation as part of implementation or works well other implementations?

Examples:

1. Audyssey has Audyssey Dynamic EQ, which could be used for loudness compensation, however DIRAC on enabled D&M devices conflicts with Dynamic EQ and both can't be used simultaneously (from what I learned). Anyway, it is mostly AV-specific.
2. YPAO Volume is organic part of Yamaha's YPAO, and it is available in all-in-one amplifiers like R-N2000a
3. Eversolo's DMP-A10 probably can combine FIR filters made with REW or it's own room measurements and loudness compensation too.
   1. And its compensation curve looks strange: https://www.audiosciencereview.com/...treamer-dac-review.55826/page-33#post-2467920, moreover loudness should be set of curves, not single filter.

I've checked few devices with DIRAC Live (like Arcam or NAD) and loudness compensation either does not exists or does not work with DIRAC.
At the moment I'm waiting for support reply about compatibility of Onkyo's Fidelity IQ with DIRAC as P-80 manual has noting clear about this.

What are other room corrections systems can woth with ISO226 curves or something like this (maybe Dolby Volume or some THX technology?)

The Monolith HTP1 has ISO226:2003 compensation which works with Dirac DLBC. The HTP1 received ART support last week, and it sounds (to my ears) like ISO226 works with ART as well but I haven't seen any official documentation on it.

CamillaDSP. You have to manually construct a filter chain from something like REW. There's a built in loudness filter with adjustable parameters

In practice, you only need one equal loudness filter for a certain amount of dB (like -20) lower volume. Apply these two filters on your preferred Dirac target curve and use that new curve for a different Dirac calibration saved in a different slot and switch to that when you are listening at low volume:

type: "LS Q",
frequency: 95,
gaindB: 8.5,
q: 0.46

type: "HS Q",
frequency: 10000,
gaindB: 2.4,
q: 1.11

This is identical to Audyssey Dynamic EQ -20dB setting.

I have used YPAO Volume and liked it very much. The main problem was, that for any source with low input level, tonal balance was wrong and there was no easy solution. The example was Qello subscription on Amazon Prime. Always sounded bad.

That is what I'm doing with Dirac. I have target curve for my prefered volume. If there is variation in source level, I correct it with volume knob and automatically get correct tonal balance.

Targets for Dirac Live

I have replaced my Yamaha AVR with Pioneer. While Yamaha does its room correction automatically, Dirac Live expect users to provide target curve. Now I'm trying to get the sound I like. My target consist of Harman curve with added loudness correction. Actually I have prepared a whole set of...

Thank you all for replies.
Few weeks ago Onkyo's support confirmed they can do simultaneously DIRAC and Loudness compensation (Fidelity IQ in theri term) in new Icon P-80.
I didn't ordered it yet though...

An AVR with THX Loudness Plus is what you probably mean https://www.audiosciencereview.com/...dness-compensation.29543/page-12#post-2505588
