You can build the CK2III for that price. It is a discrete no-global feedback design, with a laid back sound. I've built an LM4562->LME49600 headphone amp design similar to the O2, and it was just too bright and steely for my ears. Extremely fatiguing, although the distortion measured extremely low.

buying/building different amps because your headphones would benefit from EQ is a losing proposition

see the Carver Stereophile Challenge - Stereophile's professional reviewers couldn't tell a $600 Carver SS amp from their choice of "SOTA" tube amp, in their room, their choice of speakers, music - after Carver nulled his amp against their tube amp, padded his amp's output impedance to match

Headroom high end amps came with a output Z switch - trivial for a diyer to add

Linkwitz shows passive discrete "power" EQ networks for iem...

and you could give a digital EQ a fair trial

No, O2 uses through hole components.

For an inexpensive, simple build consider the glass sand hybrid, low cost and good sounding, can drive 24ohm cans. I'm just using a 24V wallwart power supply now, I have a slow start +-12 volt PCB in design to see if it makes any difference. I currently have about $50 in this project.

O2 is likely indistinguishable in DBT against any other objectively good, flat frequency response, low output Z, low distortion design regardless of technology, within its I,V output capability

but similar chip count composite/multiloop amplifiers, using "better" speced op amps released in the past decade or so are really untouchable at line level audio today - if accuracy is any part of your hifi amplifier definition

isolated bipolar, SiGe, GHz semi processes, advanced internal circuit designs by big companies competing for modern telcom, imaging market applications have taken a big step forward from the era of 4556, 5534
I agree wholeheartedly.

OP: I strongly recommend The Wire, if you can find boards anywhere.

when I have seen the title of the thread, I thought you are asking about preamplifier for the reel to reel head, at least that's what we used to call headamp

the distortion measurement was most likely not done right... if it sounds bright and steely, than measurements must confirm it...have you done IM distortion measurements? have you looked at 13+14kHz twin tone spectra?
