EQ compensation error (Patreon)

I need to apologize as I screwed up my EQ compensation for the last video of the Kii Three speakers because I had some additional compensating filter inside my recording loop which I forgot about, therefore it was "baked" into the recording with an over compensated result. I didn't notice this problem with my reference headphones, as they were looped inside the circle, but when listening over some other headphones I finally noticed that the sound appeared somehow too muffled. In the video you can hear the "old compensation" which was used for the published video and "new compensation" which is the corrected result.

I had to create a completely new compensation the next day which took me again several hours as this is not a one-click procedure because this time I tried correcting for my left and right ear separately. Formerly I always averaged over my left and right ear, but I have the impression as if the result gained a lot of additional imaging quality when equalizing my left and right ear separtely because they also measure slightly differently, thus the final result should be more correct with a better spatial resultion if these differences between left and right ear are taken into account You can hear a "mono" version of my current updated compensation averaged over my left and right ear, and the "stereo" version with left and right ear having it's own EQ, please let me know if you can hear any difference: https://youtu.be/rz_bdgCTJ9s 

Last but not least here is a demonstration how my previous compensation sounded like which was based on the Sonarworks profile and which I used it in all my former videos done with these microphones. I was never 100% satisfied with the result, especially when listening over other headphones than my Sonarworks' equalized HD600. I think the weird coloration Sonarworks introduced is quite noticeable here and I hope I managed to fix these problems with my "current compensation" which also corrects for my left and right ear separately: https://youtu.be/_LxgO6by0Oc

Let me know your thoughts please. But I think especially headphone recordings will benefit from both ears being compensated separately as basically there is way less averaging for the EQ now, just measuring several positions of the reference headphone and also reinserting my microphones between all measurements to get some additional variance and not just "bake" a single microphone/headphone positoin into the final compensation.

I also attached a corrected version of my EQ which I use for the HD600. The filters on top are directly taken from Oratory1990, below is my gain adjustment to get the same perceived loudness like without EQ (I always apply negative gain in a global preamp within EqualizerAPO to avoid clipping). The other filters below are my own adjustments which I reduced to minium not too become too different from the original Optimum Hifi profile, but they should correct for additional resonances I can hear from the HD600, therefore I also attached another HD600 EQ with stronger personal adjustments also boosting bass a bit more which for me results in a "smoother" response overall, although without claims to be "more correct".
