Not that it matters too much to me since I have made my thoughts clear on the subject, but i think your research on Tyll's thoughts about the LCD-4 is incomplete :
See his full review of the LCD-4 here:

Check out the melodrama in his tone, when he speaks about the treble, as if he has hit upon some tragedy of Shakespearian proportions:
"...Treble - All this good stuff...and then, sadly, troubles with the trebles. I've always had trouble with LCD series headphone treble, but I never really got a good grip on what I was hearing. Then the LCD-4 comes along having a somewhat cleaner response than previous models, and all of a sudden the exact problem with the treble became clear..so to speak.
Most all LCD headphones I've measured in the past have a distinct drop in treble response starting at 4kHz and going up to about 8kHz. Notches in response are harder to hear than spikes in response, and previously I didn't hear it as a distinct problem. I suppose it was obscured a bit by low level distortions or resonances in the neighborhood"... etc etc.
and now for the video, in which he repeats some of the same stuff in the review :
Finally see his post-review remarks about this, in response to other reports of other shootouts that contest his own findings when comparing the LCD-4 with the Utopia here:

My own impression has always been that the LCD-4 rocks my world, with and/or without the roon and other Audeze EQ filters. Of course YMMV, as would others. Thanks.
