stupid question but why his HD 800s EQ is so different than that oratory1990 ?
Thanks for the question.
I think it's best that you post in the Sennheiser HD800S thread instead, as more people will see it there.

That said, Amir's filters is what he thinks sounds best.
You're free to try others and see if you like them or not.

There's no right or wrong EQ...it's just a matter of preference.

i thought that oratory follow the IA prediction that is the pref curve for most people... maybe i'm naive haha

[Beginner's Guide] How to Setup Peace and Import a PEQ Profile:

In the video, I showed the following:
1. Installed Equalizer APO (ignore the error at the end, that's just because it's in a VM)
2. Installed Peace
3. Restarted
4. Opened Peace, set to 'advanced mode'
5. Went to settings, changed 'snap to db gain' from 0.5 to 0.1
6. Showed how many configurations/profiles are by default
7. Deleted all default configurations/profiles, to keep things clean
Specifically, I deleted *.peace from C:\Program Files\EqualizerAPO\config\
8. Went to ASR, to copy a PEQ profile
9. Created .TXT file and pasted PEQ profile
10. Imported PEQ profile to Peace
11. Cleanup, saved the configuration/profile
12. Showed how to view PEQ filters on a graph
13. Showed how to switch between different configurations/profiles

Overall, took 2.5min.
I know some of you are visual learners, so I hope that helps. :D

Good question. I don't know. I suppose so as it is the same fixture, test procedure, etc. But maybe an expert can correct me if there is something missing back then.

Improvements, thanks to @Matias

Added 3 previously-excluded headphone reviews.

- September 30, 2020. Amir got a Gras 45CA measurement fixture (loaner from company), and his first review was RAAL-requisite SR1a Ribbon.

- October 20, 2020: His 3rd review (with same fixture) Massdrop X KOSS ESP/95X Electrostatic. He returned the loaner fixture after this review.
- Dec 3, 2020: He announced he purchased a new Gras 45CA-10 fixture and started measuring headphones with it. All of his reviews since were done using the same fixture.

400i preset is damn on point. Best one I've tried. I only slightly tamed the bass to my preference.
Also thanks for the presets.
Glad to hear. I'm currently using Amir's PEQ profile as well, and enjoying the sound! :D

Improvements Added:

Are you using 'MathAudio Headphone EQ'?
If you're using MathAudio Headphone EQ, the software does the preamp gain adjustment automatically, in order to avoid audio clipping.
In other words, just enter the PEQ filters, and don't adjust any preamp gain.
You can tell this is true, by looking at the picture of a PEQ profile, where the highest filter (in the bass) is already at 0 dB.
