Crinicle, why didn't you just post your graphs? By the way Nick instead of finding some random graphs to your liking, try to compare stuff measured in the same rig.

Anybody see the large hump at 1.5khz? When I posted this, Audeze admitted it's peakier than that. Crinicle's graph is how Headwacker figured out where was causing the funny mids or vocals with the 1.5khz peak. Hawaiian boy, by ears figured out somewhere there is something funny in the mids. Some guys do it by ears nick. I heard incoherency in the mids, and even after EQ with DAPs, software EQ on the computer, still didn't sound right. Only LPG sounded properly driven and with EQ, the mids sounded proper. Other than the LPG, many DAPs do not have proper PEQ. You can get PEQ with Android devices, and tried those as well, Didn't sound proper.
You can go on and on about how Audeze tech is all that. Cool.
I've said it before but I'll say it again anyways for those still hazy about what's going on; it is the combo of the 1.5k peak and the 2-4k null that makes the Audeze portaplanars sound so weird. That is not to say that the reason for the weirdness is not solely due to the specific peak or null but rather both happening at the same time. The Campfire Jupiter is the most recognisable example of an IEM with a 2-3k null but does not sound as weird as the portaplanars because the latter have one very distinct difference: a 1.5k peak.
I guess my words got lost in translation at the start, I didn't say that the 1.5k peak is the only reason for the weirdness but rather is the reason for the unique weirdness that the 10/20/i4 exhibit.
I have a gentleman's agreement with Nic to not bring my data into this thread. At any case, I can find industry-standard graphs of the IEMs he listed so it's a non-issue.
What these graphs prove, is yet again, a powerful combination of overconfidence in a $50 measurement setup, with a complete lack of understanding of what specific frequencies do.
The frequency range is a gradual, and therefore linear, rise from low to high tones. So if a bump between 2-3 Khz is an ideal response, then a bump between 1-2 KHz is only a
slightly less ideal response; it does not have a completely opposite effect. You saw your graph months ago, and then made up a theory about the effect of the 1.5 KHz frequency based on one isolated observation.
This is the actual issue:
I show a graph by Tyll, who has over ten years of experience in measuring and uses a professional measurement setup. That graph shows a strong dip between 2-6 KHz which coincides with the issues in imaging, transparency, and note weight that I heard using my ears, and interpreted with actual knowledge and experience with frequencies. But no, that graph should be ignored. And then Crinacle mentions he didn’t even hear what I am mentioning in the first place. But despite not even knowing what I’m talking about, I have to hear that I am wrong and get schooled on frequencies.
Then I argue that Audeze’s DSP settings clearly show that the 1.5 KHz is not changed AT ALL; the major difference is that the 2-6 KHz is strongly elevated. This not only coincides with my EQ settings, but
Audeze’s own recommended EQ settings.
Then I show graphs of other iems that have a peak in the similar region to explain that a 1.5 KHZ does not have a negative effect. This is again totally ignored because it doesn’t suit your narrative. The 8.2 graph is never acknowledged. And Silverears, just because you use two graphs from the same database doesn’t mean that that one is correct and the NT6 therefore doesn’t have a peak at 1.5 KHz. That’s really not what people mean when they say you should compare graphs from the same setup. Besides, how can I compare graphs from the same database if I wasn’t using that one in the first place? Simple logic must be a distant acquaintance to you.
But my favorite argument is where you keep repeating that the 1.5 KHz bump is the issue, then add that the problem isn’t fixed after that, while failing to see the irony in the weakness of that argument. I will say it explicitly because I'm pretty sure you still won't understand: the fact that your EQ settings didn't work negates your whole argument. The EQ didn't work because your settings were wrong in the first place.
You make one observation of a 1.5 KHz peak based on an amateur setup, and build a whole theory about what that frequency does, defying the basic logic of how the frequency range works. This is like saying the ideal listening volume is at level 80-81. But I once tested this iem I never heard before at level 79 and it sounded horrible. Therefore, the only logical conclusion must be that level 79 is THE ABSOLUTE WORST VOLUME TO LISTEN TO. Frequencies do not have absolute effects. They must always be interpreted in relation to other frequencies.
You have the arrogance to tell me to use my ears? How about instead of looking at a crapty graph you actually use EQ and literally try to use your ears? Lifting 1.5 KHz does not mask vocals or make them less transparent. It makes vocals more forward. If that were true it would mean that a dip at 1.5 KHz would therefore theoretically be a better tuning than a straight line (which has never been applied), and an ideal response would have a dip at 1.5 KHz followed by a peak at 2 KHz, which is both logically and practically impossible. But let’s be honest, I’m not going to fool myself into thinking simple logic is going to come through that dense wall. Because you have your graph, and have made up your mind about it a long time ago.
And no Crinacle you did not say it was the combo. You just kept repeating in several posts it was only the 1.5 KHz peak that affects vocals, because as we can now see you blindly went off your own graph. I tried to explain it was not the peak, but especially the strong dip in the 2-6 KHz range and the discrepancy between the two. But even now you keep on saying the 1.5 KHz gives this ‘unique weirdness’, which shows you still have absolutely no idea what you’re talking about.
