Audeze has on hand the frequency response curve for your specific headphones, and will send it to you on request. I had printed mine off, and adjusted it to make it look like the Harman curve.Keep tinkering with my EQ for the LCD-X 2021, it's implemented on the "RME Adi-2 Dac", hence it's limited to a few settings:
Low shelf 65Hz, +4,5 dB of Q 0,8
Peak 230Hz, -1,0 dB of Q 0,7
Peak 950Hz, -1,0 dB of Q 0,5
Peak 3500Hz, +2,0 dB of Q 2,0
Peak 11.700Hz, -3.0 dB of Q 3,0
For the RME users I would like to add, I like it also with „Crossfeed“ level 1 (a bit)
in combination with „width“ 0.95.
Critical feedback for further optimization is welcome
4000 Hz or so, I had raised 4 to 4.5 db most of them need more than 2 db.
I had low shelved at 1700 Hz by 1.5 db, to flatten out the curve to 2000 Hz, while leaving the factory provided gentle bass rise in place. You are doing a similar thing with your 230 Hz and 950 Hz cuts. My bass doesn't drop until 38 Hz and I had put a low shelf there.
-1 db is inaudible to me. Your Q values are rather broad; there's tools where you can see what you are doing graphically
