The measurements are what kept me from buying them for months but recently there have been 7 things that made me realize my ears are perhaps not exactly "Harman-tuned" and FR measurements do not reflect whether I enjoy a given headphone or not

:
1) While listening to my EMU Teak extensively, while I generally really like their sound, especially their mids and treble, often I kept getting bothered by their bass, which sounds to me like there is too much of it and it overpowers the rest of the frequency spectrum (note how close the Teak is to the Harman curve according to many measurements, especially the bass)
2) My Denon D5200, while most graphs show that they have more bass then the Teak, do not exhibit the above mentioned bass behavior and sound much more neutral (I think it is because they have, according to FR graphs, stronger response in the 100-300Hz region than the Teak, which masks the deep bass. I have confirmed this by EQ'ing the D5200 to have more similar bass response to the Teak and yes, suddenly, they started sounding like they have too much deep bass, similar to the Teak. Thus I concluded that I am not a fan of Harman bass and prefer a bump in the upper bass region)
3) Most measurements show that the Teak has a peak in the 10KHz region and there are people who say that this makes them sound aggressive in the upper treble, maybe even sibilant. I really like their upper treble unEQ'ed, do not found it sibilant and if anything, find the peak pleasant and that it partially nicely balances the bass
4) I really, really like my Grado SR325x, which are, according to
measurements, not really very Harman-compliant, with peaks at around 2, 4.5 and 9 KHz (and dips in-between). I must say, again, that I love how they sound, unEQ'd. Also, Grados are generally considered quite "wild" in their FR. Not sure if the SR325X is less "wild" than other Grados, but their sound is what I was looking for with open-back headphones
5) I bought the Sony MDR-1AM2 not long ago and I like their sound very much, while measurements show that they have way too much bass even for Harman and a huge peak around 8KHz. Love how they sound, unEQ'd (they are my "wild" headphones)
6) After Amir reviewed the 7Hz x Crinacle Zero:2, I decided to buy them. They sound very nice, but I still prefer my Sennheiser IE300, which is quite far from the Harman curve, FR-wise
7) I tried EQ'in my Denon D5200 to have as similar a FR to the Z1R as possible, including a bass boost, a ~3.1KHz peak, 4-6KHz dip and a ~10K peak and I found the resulting sound very pleasing
So I no longer consider FR measurements to be an important factor in whether a headphone will sound good to me or not, unless the FR shows completely missing bass or some huge holes or peaks in the audible spectrum. However, now I do not have a source of good information on headphones, because what else is there except for measurements? Audiophool reviews full of nonsense words that get my blood boiling like "micro and macro dynamics", "microdetail", "musicality", "soundstage width/depth" and all the other blabber that audiophool "reviewers" use to shill expensive stuff. No, thanks.
Back to the L30: I think I will just do one listening session where I will try to find if I can hear any difference with the MDR Z1R between the L30 and my Shanling UA3 and if not, will listen to them via the UA3. At least it has a 4.4mm output. Not that I expect the Z1R to need a balanced connection, it's just that the SE cable they come with is 3 meters, which is way too long, while the 4.4mm cable is a much more manageable 1.2 meters
