These are the EQ curves, not the frequency response of the headphone after EQ. So all of them, it's bringing up the upper mids substantially over stock. I just do it a bit less than Oratory or Resolve in my last one, my EQ is smoother/darker than Oratory's EQ. It's substantially less dark than the stock tonality which is much too dark.

How much exactly is personal preference, I found Oratory1990's Harman just a bit too much. I don't on most other headphones, I use his Harman presets extensively. But on this one, a bit too much. I found it just a bit better without quite as much of a boost. But exactly the level is personal preference, the bands I reduced by -2dB were the treble high shelf which raises everything over 1,800Hz and the presence/sharpness at 3,850Hz.

The one other headphone I brought Oratory's preset down in the upper mids was the HE6SEV2. Most of them I am good with his Harman preset as is in the upper mids, I usually just add a bit more air (his presets often cut the air, I usually leave this out).

The LCD-X is a lot punchier than than the Arya or HD800, and I think also even than the Clear, while also having much better sub-bass extension than the Clear.
