This post in response to
@TheAttorney regarding the merits of the angled Alcantara pads and addressed to all readers will cover my EQing methodology, my closer comparisons between the Meze Elite Tungsten and my HiFiMan Arya Stealth, and why I believe that EQ can yield results substantially improving on top of either of these headphones' earpads' and drivers' stock tunings.
EQ setup and fast headphone A/Bing:
You can obtain my latest
Equalizer APO setup here:
https://drive.google.com/file/d/13DMX1xImBsQjzRK2bbB565txfQGSRMp8/view?usp=share_link (update: I've realized that not everyone has Gmail, so I have attached the .zip file here, and also added the text under each EQ profile shown).
To quickly switch between two headphones, I put their respective includes next to one another as in the config.txt file depicted below:
Then, while simultaneously using my left hand to flip the knob of the upper switchbox to the other headphone, I click on the "power icons" to switch to the target headphone's EQ and preamp settings. Either before or after this quick EQ and switchbox switch, I quickly physically switch from wearing one headphone to the other. This takes around 5 seconds, plus the delay of restarting the track you are comparing.
Stock tuning and earpad impressions:
tl;dr: The hybrid pads are too warm to me, but have bass extension and distortion characteristics plus preferred comfort and presentation that make them preferable to me as a platform for EQ. The angled Alcantara pads do sound agreeable, but I don't hear any advantages in soundstage or imaging, and still prefer the results of fine-tuned EQ.
As in
post #4,660, hereon, I will not be re-embedding the links to music track videos I had already linked, whereby I will only refer to them by the name I used in quotations.
I personally find the Meze Elite's stock tuning for the
hybrid pads too warm in the bass and mids, and lacking in the upper mids or ear gain region. Likewise, I've found that at least with my ears, even with the default Harman EQs, the treble region around 5 kHz to 8 kHz tends to sound too bright, forward, or unnaturally amplified. This makes the music I listen to (see my past few posts for examples) sound a bit muffled, dulled, veiled, or "hollow", like I am listening over a boom box from the early 2000s whence I was a wee lad, or inside a tube, whereas my ideal sound is exquisite vibrance, vividness, and clarity. Basically, while the stock tuning can lend a nice touch to more "lean" genres or tracks (in the sense of having more isolated bands for instruments as opposed to at any moment already taking up a substantial swath of the audio band), for spectrally busier recordings, tonal balance can be extremely important. Or with acoustic or orchestral tracks, you would definitely be prioritizing timbral accuracy, which as far as I know is indeed best captured by the Harman or diffuse-field target insofar as neutral speakers do produce a smooth bass and midrange response at the eardrums followed by an ear gain region between 1 kHz and 10 kHz that reflects how most human ears actually amplify sounds within that frequency band. But as you will find in this post, following the targets as-is is not guaranteed to yield the best results possible, whereby you may still need to do a lot of work in "EQing by ear" to dial in the EQ profile to nigh perfection. Anyways, there are some tracks where I can enjoy the warmth of the stock tuning, but I have so far sound my fine-tuned neutral EQ to be best all-rounder, giving me a clear view into any track.
As for comfort, the hybrid pads feel great and compared to the other headphones I have covered other than the Arya provides the most even pressure distribution all around my ears. I still feel that the Arya's
HE1000-style pads (two and a half months worn-in) fit more perfectly around the sides of my head, its being very quick and easy for me to put them on and get the perfect seating, whereas I do need a bit more adjustment for the Elite, maybe less once the pads get more worn-in, though the patented suspension strap design has more give than on the Arya, making. Even when EQed to sound nigh identical, I can still at different times find myself preferring to enjoy the feel of one of these headphones' pads over the other's, their both having pleasant things to be enjoyed about them.
As for the stock tuning of the
angled Alcantara pads, I do agree that they are an improvement over the hybrid pads in terms of clarity, and are quite acceptable for listening to classical and acoustic music, though I still find its bass a tad too much at some points, and still desire more out of its ear gain region. Likewise, at least to my ears, there might still be the 6 kHz to 7 kHz peak that sticks out within pink noise (my typical comparison listening level is around 83 to 84 dB; I use
https://download.cnet.com/BurninwaveGenerator/3000-2169_4-10711592.html as my pink noise source) and spectrally busier tracks, whereby EQing this, and any other remaining flaws down would likely enable a yet cleaner sound. Compared to my reference neutral EQ, pink noise through these pads sounds a bit darker, but otherwise reasonably balanced without noticeable peaks, hence being suitable as an alternative tuning for some of my tracks. Otherwise, for adjusting the tuning to better showcase the headphone's "technicalities" and capabilities with respect to the competition, I think these pads do a great job and can sound very good with certain tracks. Regardless, I still find my final EQing results with the hybrid pads to be tonally superior, presenting to me a worthwhile improvement over relying on "EQing with earpads". Furthermore, the hybrid pads have better bass extension and lower bass distortion (the latter measurement result can be
here; the angled Alcantara pads do have slightly lower midrange distortion, though; I confirmed with tone generators, well, clicking around a sine sweep video I use for EQing by ear, that the angled Alcantara pads do have a subbass roll-off as measured), qualities which I can still value for classical or acoustic music (e.g. taiko drumming and Chinese orchestra), making them my preferred platform for EQing the Meze Elite.
As for comfort, I find the Alcantara's texture a bit too "rough" compared to the exquisitely gentle and welcoming feel of the fabric that lines
HiFiMan earpads. The angled Alcantara pads also feel a tad stiffer or not as compliant as the hybrid pads, not yielding as snug of a seal. Likewise, as you will see below, though the size of the ear "aperture" is the same as the hybrid pads' which is comparable (slightly shorter but wider) to the Arya's, these pads are quite thicker:
Angled Alcantara versus HE1000-style pads: back
Angled Alcantara versus hybrid and HE1000-style pads: front
I think this thickness causes the headband's clamping force to apply a slight forward torque that has these pads feeling less stable on my head than the hybrid pads or the Arya's. I guess for me, the less the headphones stick outside of my head, the better.
As for
soundstaging, taking into consideration my stances already described in
post #4,660, I don't experience that much of an advantage compared to the hybrid pads, mind I might even still prefer the latter's "presentation" of large soundfronts like the orchestral tuttis that open Mahler 5 in
https://app.idagio.com/recordings/43791766 (for reference, my comparison volume for those dynamic peaks is around 95 dB, the rest averaging around 80 dB), or with Susumu Hirasawa's "Parade" (peaking at 90 dB)i. Here, the Arya still sounds the most immersive or "spatially transparent", perhaps both thanks to how the pads feel around my head, and how they are the most open sounding to me; e.g. when speaking, the Arya yields minimal attenuation of my voice to my ears, the Elite's pads or driver yielding a mild muffling or attenuation of higher frequencies, the angled Alcantra possibly less so. I suppose that while the angled pads may be thicker and deeper, this doesn't really feel any more "open" to me, or something about the material and the larger inner walls of the pads has these pads actually feeling more closed-in than the hybrid pads. Perhaps you can imagine sound radiating from the drivers a bit outward, whereby the deeper the pad, the more that sound will intersect with and be absorbed by the walls of the pads, and as such, I feel like I am receiving a smaller part of what the drivers have to give me. Perhaps they do sound a tad "wider" with the drivers being further away, but I think this needs to be balanced with one's also increasing the size of the ear aperture, say, a centimeter forward and backward.
As for openness, there is also the matter that the Meze Elite and Empyrean both obstruct the back of the driver with the fancy yoke design, as nice as those look, such possibly reflecting some sound back around that area, though I wouldn't be one to know what a Meze Elite with yokes purely coming in from the side would sound like.
As for
imaging, I don't hear much improvement over the hybrid pads, or the differences between these or the Arya are too minor for me to care, whereby my stance in
post #4,660 regarding imaging applies.
As for
the Arya Stealth's stock tuning, this sounds too veiled and bright to me in a manner consistent with frequency response measurements, the bass being slightly lifted, the upper mids recessed, and there being audible peaks that you might not realize were dirtying the sound of your spectrally busy track (e.g. "Parade"), though some tracks can still sound pretty good, though the treble may indeed be a bit forward compared to my EQed results.
EQing journey - HiFiMan Arya Stealth:
tl;dr: EQ can do wonders for improving clarity and separation, and to me is the best way to achieve sonic transparency into the recording, presenting the music as it is, neither adding nor taking away anything from it.
Let us start by looking at my original "HiFiMan Arya V3 EQ headphones.com GRAS target V1.csv" Eq profile based on the frequency response measurement shown here.
Text: GraphicEQ: 20 3; 30 2; 40 1.8; 50 1.5; 60 1; 75 0; 80 -0.5; 100 -1; 150 -2; 200 -2; 300 -2; 350 -2; 400 -1.5; 430 -1.2; 500 -1.5; 540 -1.7; 600 -1; 700 0; 830 -1.3; 940 0; 1100 0.5; 1200 2; 1400 4; 1600 5.5; 2000 4.5; 2500 0; 3000 -1.5; 3200 -1.8; 3500 -1.5; 4300 0.8; 5300 -3.5; 7700 -2.5; 9100 0; 10200 -2; 12500 0; 14000 -2; 17000 -3
This sounded great to me and served me for a month, greatly improving clarity, but I was not yet aware of the remaining peak around 5 kHz to 8 kHz, or the resonances around 4 kHz. It was then in mid March that I decided to try "EQing the treble by ear" to sound flat. These issues were revealed by listening to
pink noise (I use
https://download.cnet.com/BurninwaveGenerator/3000-2169_4-10711592.html as my generator) and
sine sweeps as in
(I do acknowledge that not everyone will be as tolerant to listening to pink noise and pure tones at 80 dB for hours on end while chasing that perfect tonal clarity.) When listening to sine sweeps, I keep the curves of my EQ profile, the headphone's frequency response with headphones.com GRAS Harman target, and the
equal loudness contour as references to check whether I expect the perceived volume of the pure tones to be increasing, decreasing, or constant in volume. I adjust the Equalizer APO Graphic EQ profile accordingly and add or remove points if needed. If I hear a smaller fluctuation, I correct it until the loudness of the pure tones sounds smooth though that band. Variable-band Graphic EQ gives a "connect-the-dots-like" control as opposed to being limited to using parametric EQ filters as your building blocks.
This culminated with "HiFiMan Arya V3 EQ headphones.com GRAS target V1 - adjusted by ear - tamed highest treble compensation.csv" shown below:
Text: GraphicEQ: 10 4; 20 3; 30 2; 40 1.8; 50 1.5; 60 1; 75 0; 80 -0.5; 100 -1; 150 -2; 200 -2; 300 -2; 350 -2; 400 -1.5; 430 -1.2; 500 -1.5; 540 -1.7; 600 -1; 700 0; 830 -1.3; 940 0; 1100 0.5; 1200 2; 1400 4; 1600 5; 2000 4; 2500 0; 2700 -1; 3000 -1.5; 3200 -1.8; 3500 -1.5; 3990 3; 4200 3; 4300 -1.5; 5300 -3.5; 6500 -4.5; 7700 -2.5; 8100 0; 9100 0; 10200 -2; 11000 -1.5; 11500 -5; 11900 -5.5; 12500 0; 13000 -1; 13600 7; 14000 3; 15000 3; 15500 -3; 16000 -3.5; 17000 0; 18110 1.8; 19154 2.4; 20258 3
Here, I had somewhat addressed the 4 kHz resonance, and likewise some resonances and dips in the treble. My top octave treble particularly caused a higher-pitched percussion instrument to appear within the upper right of the sonic image within the middle of Yosi Horikawa's "Crossing". It was by mid April sometime after my initial audition and order of the Meze Elite that I in spectrally busy tracks like "Parade", in pink noise, and then in the sine sweep realized that despite my expectation of a monotonically decreasing loudness in pure tones from 4 kHz and on, it was actually increasing to a rather loud peak around 6 kHz to 8 kHz (you can experiment with Equalizer APO's parametric peaking filters and pink noise to hear what those peaks sound like so you can identify them and EQ them away). In EQing this down, I noticed that the sound of "Parade" and orchestral works had been cleaned up, my having not realized that it actually used to be too bright and was polluting the sound with this treble
noise (practically speaking). Likewise, "Parade" and orchestral works sounded more spacious, perhaps as though violins had a sense of increased soundstage and now had the correct tonal balance. Given this, I recommend those of you who EQ to check out this band on your headphones and see if it might in fact be too amplified for your own ears as it was for mine.
I would later after picking up my Meze Elite Tungsten over the last week refine my "reference neutral EQ" for the Arya, cleaning up the treble and also addressing an area around 3.5 kHz that was still sticking out in pink noise. I gave in with trying to EQ the resonances between 3 kHz to 4.3 kHz since the location of the peaks and dips would change with each removal and donning of this headphone, whereby it would be best to leave the EQ around that region flat so that compensations from a previous seating won't accentuate peaks or dips in another one. Again, this problematic resonance region is corroborated by the CSD shown
here. In this regard, the Arya has this disadvantage in regard to frequency response consistency and "EQability". Anyways, this EQ culminated with "HiFiMan Arya V3 EQ headphones.com GRAS target V1 - adjusted by ear - neutral reference V1 - flattenend 4 kHz region due to inconsistency of resonances.csv" shown below:
Text: GraphicEQ: 10 4; 20 3; 30 2; 40 1.8; 50 1.5; 60 1; 75 0; 80 -0.5; 84 -2; 100 -1; 150 -2; 200 -2; 300 -2; 350 -2; 400 -1.5; 430 -1.2; 500 -1.5; 540 -1.7; 600 -1; 700 0; 830 -1.3; 940 0; 1100 0.5; 1200 2; 1400 4; 1600 5; 2000 4; 2500 0; 2700 -3; 3000 -3.5; 3200 -2.5; 3500 0; 3600 2; 3700 2; 3850 0; 3900 1; 3950 1; 4000 1; 4070 2; 4100 1; 4140 0; 4300 -4; 4800 -6; 5000 -7; 5300 -8; 5500 -7; 6100 -10; 6500 -9.5; 7000 -10; 7700 -10; 8100 -5; 9100 -2; 10200 -2; 11000 -1.5; 11100 -2; 11600 -9; 11900 -8; 12100 -6; 12500 -4; 12800 -4; 13000 1; 13600 -1; 13800 -1; 14000 0; 15000 0; 15500 -3; 16000 -3.5; 17000 0; 18110 1.8; 19154 2.4; 20258 3
All I can say is that this sounds
great. Just clear and balanced, with everything sounding as it should to me. I will also vie that neutrality or "clear and balanced" does not at all sound "sterile" or "lifeless" to me. When there is warmth in a recording, it will shine through. If the track is "fun" (as I have particularly found with Susumu Hirasawa in places), oh yes, will the headphone make it sound "fun". It is presenting the music as it is, and yes, sometimes you can from this neutral reference critique a track's tonal balance and adjust it accordingly with EQ (see "Tone Adjustment Console.txt"). From what I have gleaned about audio, the idea is that when you have peaks in the frequency response, this frequency bands can mask details situated adjacent to that band while possible bringing that band too far forward. Now, while in-ear measurements of reference speaker systems might actually yield a rough (lots of small rises and dips or resonances or reflections) measured frequency response, and you may also be able to hear such in sine sweeps played through that system, I have the stance that a very smooth frequency response or perceived sine sweep could still be regarded as a more "ideal" way of hearing, or an enhancement over human hearing provided that our "actual" equal loudness contour isn't actually already very smooth, whereby the only roughness would be in the recordings themselves as originate from the instruments, recording environment, or the recording equipment and chain itself. As such, a very smooth frequency response without peaks and dips where they shouldn't be is what I regard as "true audio transparency", or the best way to create a portal between your ears and the recording itself, indeed making the transducer (headphone driver) disappear provided that that happens to be your own audiophile goal, to get rid of imperfections and hear the music alone,
only then applying tonal controls to suit one's preference.
As such, as I have read and heard some say, I would be weary about giving in to finding a peaky treble "detailed-sounding" or "highly resolving", but by all means, you can still enjoy such a sound signature. As for pink noise, this EQ profile now sounds very balanced, with virtually nothing but the top octave and that problematic 4 kHz resonance, or the entire ear gain region itself (which is suppose to be there) sticking out. This EQ produces the most realistic orchestral timbre among others for me, and exquisitely rich and clear piano tones within
Grosvenor's Chopin Piano Concerto No. 1 (take 7:30 and on, for example, where I find the angled Alcantara pads slightly veiled due to the still prominent bass, still slightly relaxed ear gain region, and the 6 kHz to 7 kHz treble energy, or it still sounds too warm or dark, or a bit of the body of some of the strings is still partly robbed).
Susumu Hirasawa's music in general presents plenty of quite busy tracks with which one can test for clarity, tonal balance, peaks or masking, and instrument separation:
- "Technique of Relief":
- "Gipnoza":
The angled Alcantara tracks do sound good with these tracks, mainly slightly quietening the vocals and bringing some of the bass and mids forward.
EQing journey - Meze Elite Tungsten with hybrid pads:
tl;dr: It is indeed possible to EQ two headphones to sound virtually identical if you do it right, adjusting and volume-matching them frequency-by-frequency by-ear, their then only differing in soundstaging, earpad size and comfort, imaging (probably mostly related to driver matching), and transient quality, but one headphone can still be superior for EQ insofar as it has lower distortion, greater frequency response consistency, and less resonances, peaks, or dips. (See
https://www.audiosciencereview.com/...n-susvara-headphone-review.50705/post-1853760 (post #1,137) for a more precise matching of two headphones using in-ear mics.)
Below is my initial "Meze Elite headphones.com GRAS target V1.csv" EQ profile based on the frequency response measurement shown
here.
Text: GraphicEQ: 20 3.8; 50 3.9; 63 0.6; 80 0; 125 -1.5; 200 -3; 240 -3.5; 335 -3.5; 350 -4; 420 0; 440 0.9; 500 0; 560 -0.3; 670 -0.2; 750 -0.5; 830 0; 900 1.5; 1060 0; 1200 0; 1400 4.7; 1700 4; 1920 5.2; 2250 5; 2500 2.8; 2850 2.5; 3150 3.2; 4000 1.8; 5400 3.9; 6100 1.6; 7300 4.8; 8000 2.7; 9350 2.7; 12000 -1.2; 12500 0; 13000 1.8; 14000 -3; 14800 0.5; 16400 -9.8; 20000 -9.8
This was the EQ responsible for my coming to somehow prefer the Elite over all the other headphones auditioned and prefer some things about its tonality over my Arya. The first observation was that the "sweetness" I had heard in the guitars at 1:39 of "Diablo Rojo" was indeed grounded somewhere within the frequency response, in this case, within the EQed shelf around 400 Hz. When I listened through sine sweeps in that area again, I cam to realize that this region actually was in fact too elevated. I initially thought that I didn't hear the shelf at all, but then found that the decrease in volume around there was simply smaller than what the frequency response measurement suggested, whereby my original EQ had overcompensated this drop in volume, causing this "sweetness" to appear which I would have not EQed in for any of the other headphones since those all had rather flat bass to midrange responses. Regardless, I still regard the Meze Elite Tungsten as being aesthetic perfection and an engineering marvel, a lovely work of are that both sounds great and happened to be the most comfortable to me out of that lot.
"Aesthetic perfection". Who wouldn't love to be greeted by this sight every morning?
Listening to the sine sweep of the top octave (10 kHz and up) revealed what was actually a very clean, smooth, and extended treble response other than the 14 kHz dip/null which I believe is a natural destructive interference that can't be EQed away; I think the Arya's 9 kHz dip wasn't as deep as on the Elite, and I think the Arya does also have a 13 kHz or 15 kHz null like the Elite, just that it didn't rebound as much or quickly as on the Elite which unEQed has more 15 kHz than the Arya, though the Arya seems to still have more 10 kHz. Note that the B&K measurement for the Elite shows a large peak around 15 kHz; I don't think I really heard this as a peak, its more so manifesting as this smooth and largely sustained treble extension. I also made note that through the ear gain region and top octave, the Elite's frequency response generally sounded a lot smoother than the Arya,
and the imaging of the pure tones was more consistently central, suggesting better channel balance or driver matching compared to the Arya which had ought to be a semi-objective demonstration of the Meze Elite having an edge on imaging capabilities over the Arya, however hard that might be to hear in practice, and whether or not this clean driver matching can also be achieved on much cheaper headphones (or such cheaper headphones would inherently lose out on other qualities).
I had also created an EQ profile for the B&K target shown
here (it's the last EQ profile shared in the main post). Below is "Meze Elite headphones.com BnK 5128 target V1 - only up to 8440 Hz - adjusted by ear including more spacious treble.csv":
Text: GraphicEQ: 20 0.7; 23 0.7; 24 0.4; 28.5 0.4; 33 0; 38 -0.8; 41.4 -0.2; 45.5 -0.6; 47 0.5; 60 -1; 100 -2.6; 140 -3.3; 200 -3.9; 320 -5; 340 -4.5; 410 -2; 470 -2.6; 610 -3.3; 740 -1.1; 815 1.1; 900 0; 1000 -0.8; 1170 0; 1240 2.9; 1450 1.8; 1650 3.5; 1810 5; 1860 5; 2150 5; 2250 3.5; 2420 4; 2750 4; 3000 4.2; 3220 3.5; 3370 2.2; 4000 2.1; 5000 -1; 5600 -3; 6000 -5; 6200 -7; 6500 -5; 6700 -4; 7200 -3; 7800 -4; 8200 -2; 8440 0
This EQ includes my "spaciousness" compensation for the peak that I hear around 6 kHz. I otherwise hadn't really fine-tuned this EQ, its still having some frequency bands sticking out within pink noise like around 2 kHz, and found that my ears probably matched up more with the GRAS measurements.
I eventually while listening to the aforementioned Mahler 5 and Chopin Piano Concerto No. 1 found this hybrid pad EQ wanting of more clarity compared to the Arya, even after EQing by ear a similar correction of the 6 kHz to 7 kHz peak I was hearing (what I call my "spaciousness EQ"). I came to find that what was likely happening was that the EQed Elite still had a bit too much bass, and that the serendipitous "sweetness EQ" of a raised 400 Hz to 700 Hz region was what was responsible for this loss of desirable clarity compared to my reference Arya EQ. As such, I with the help of my quick headphone switching volume matched the Elite's pure tones with reference frequencies on the Arya. I sometimes made adjustments to the Arya's EQ, too (e.g. upon noticing the remaining 3.5 kHz peak), but still this time had the goal of matching the two headphones as closely as possible to what I can only call "endgame EQ".
Below is my final "Meze Elite headphones.com GRAS target V1 - adjusted by ear - neutral reference V1.csv":
Text: GraphicEQ: 20 3; 50 2.5; 63 0; 80 -1; 125 -2; 200 -5; 240 -4.5; 300 -4.5; 420 -3.5; 500 -3.5; 600 -4.5; 670 -3.5; 750 -1.5; 830 0; 900 0.5; 1060 2; 1200 4; 1300 5.5; 1400 5.5; 1600 6; 1700 6.5; 1920 5.2; 2250 5; 2500 2.8; 2850 1; 3150 0; 3500 0; 3750 0; 4000 1.8; 5000 1; 5400 -2; 6000 -6; 6300 -8; 6800 -7; 7300 -6; 7800 -5; 8000 -3; 9350 0; 10000 0; 12000 0
Indeed, with this meticulously obtained EQ (for my ears), these two headphones are now about as volume-matched as they can ever be, and sound virtually identical
tonally per music timbre and the sound of pink noise other than the Arya still having those 3.5 kHz to 4.3 kHz resonances. The only differences are in transient quality as already described in
post #4,660, the Arya still being the king out of this lineup for transient sharpness, though the Elite's transients might still feel "weightier" and hence preferable for certain tracks or at certain times. Likewise, differences in soundstaging are subtle, or to me ultimately boil down to the subjective effect of how the pads feel. Both feel great when I switch to them, and that suffices to have me happy to be able to switch between two tonally identical headphones, else indeed, switching headphones allows those pads to cool down so they will feel nice after switching back to them once the other headphone's pads get warm. Even if I have found that despite what I originally liked about my original Elite EQ, I would indeed still lean in favour of my Arya EQ's clarity, and while I cannot say that the Elite as a pure platform for EQ actually
sounds better, though it does probably have better driver matching and lower distortion, I am still very happy to be able to present this (to me) tonal perfection through this work of art. Likewise, if I didn't like either headphone's stock tonality in the first place, but still substantially preferred their
presentation and other non-tonal characteristics, then I might as well EQ both of them to the same neutral reference EQ and use other EQ methods (see "Headphone simulation EQs applied to current Arya and Elite reference EQ.txt" and "Tone Adjustment Console.txt") or the removing of some parts of the EQ profile to experiment with tonal balance.
The final frontier:
tl;dr: I think I have already achieved "endgame EQ" for tonal balance and clarity. EQ is powerful and is a legitimate way to experiment with tonality and modify or emulate headphone sound. Given this, the next step for me other than looking for yet nicer recordings is most likely in pursuing HRTF measurement and head tracking for improved forward imaging and spatial immersion.
From this point in my headphone journey, my goal is to either come across a yet better platform for EQing featuring a yet smoother frequency response, a cleaner CSD, less resonances, yet sharper transients, better driver matching and hence imaging, and a better perceived soundstage from the driver size and earpads, or to finally be properly amazed by a stock tuning for which I would truly feel that EQ would be a disservice to it.
In "Headphone simulation EQs applied to current Arya and Elite reference EQ.txt" shown below, I based on Crinacle's measurements produced these EQ profiles relative to my personal neutral reference in order to simulate the tonal effects of how each of these headphones modify the midrange and ear gain region from 5 kHz to 4 kHz. All except for the Final Audio D8000 Pro whose bass is slightly raised had virtually the same, highly neutral bass to midrange response, mainly differing in the aforementioned band. As for their trebles, my stance is that I would probably find the majority of them veiling or hear peaks in some way that would need to be EQed anyways, whereby my current treble to top octave EQ is what "perfect treble" sounds to me. In this case, I would expect the LCD-5 to mainly bring vocals a bit more forward and slightly increase that sense of clarity. The D8000 Pro would do similar, but eat up too much from the 2 kHz to 4 kHz region, causing it to sound dulled there, yielding an unnatural ear gain sound, though I might like that sound for some tracks. the Focal Utopia's ear gain EQ only adds a subtle sense of increased or modified clarity. The Sennheiser HD 800 S's ear gain dip indeed makes
everything in that range sound more distant or quieter, which I personally don't like, though in practice, that headphone's stock tuning is still very agreeable for classical music. Finally, the HiFiMan HE1000se's 1 kHz to 3 kHz ("early ear gain", as I call it) dip does make everything in the midrange, particularly vocals, sound more distance, perhaps giving them a bit more of a sense of space.
Anyways, the point here is that EQ can be a whole lot more powerful than you think it is, and this shouldn't cause one to be dismayed by the prospect of headphones converging upon the same target so much as your turning your favourite headphone
to wear into an excellent platform for tonal exploration that doesn't require having to actually physically reach for another headphone or set of pads, or for which tonal adjustments can be immediately tested with a click of the mouse. I can still believe that there are things that high-end headphones or those within each tier can do that other headphones can't, but in that regard, my stance is simply to effectively pick your favourite "window into the musical world", choosing its frame and the size thereof (earpad and driver size and dimensions), and then choosing your favourite glass tint or lack thereof (tonal balance; distortion and veiling could be seen as blurriness or fogginess, and peaks could be seen as texture or waviness causing light to focus at certain parts of the otherwise clear glass).
Otherwise, I still feel like HRTF measurement and head tracking are still the main frontier for me insofar as I do not yet have the means to attain a proper listening room for speakers. Yes, it can be advantageous to be able to "rotate the entire concert hall with you" as you move your head, but I still feel that head tracking is absolutely essential to proper immersion and actually feeling like you are there, the HRTF changes reinforcing your sense of imaging with the sound sources staying fixed in space.
2024-02-08 update:
I had in September acquired in-ear mics from
https://www.earfish.eu/ and by latter October finally received my HRTF SOFA files and EQed my headphones toward my free-field measurements.
This is the absolute greatest breakthrough in my audio journey. The clarity, vividness, and imaging for great recordings is simply unreal. See
