Well, I return to this thread to leave the short review I promised to. Albeit later because I honestly have been spending all my free time listening to them almost nonstop.
My setup is a Marantz HD-DAC1 on Medium Gain into the Focal Clears with Foobar on WASAPI (event) and FLAC files.
My previous setups were an O2ODAC with Senn HD 598's then Beyer T90's then DT 1990 Pro's and most recently Beyer T1's that I returned within 2 weeks and used the money to fund the Clears.
I suppose there really isn't much point comparing them to my previous mid-fi purchases, but the T1 warrants some comparison:
The T1 has "more" bass - it's not as tight and not as precise as the Clears but there IS more of it.
Treble - while still bright there is no annoying spike on the Clears as is on the T1's.
Comfort - both are amazingly comfortable to me, maybe the Clears edge them out a little (though it did take me like two days to get used to the way the Clears clamp with the spring loaded cups).
Instrument separation - the T1 is better at it but because of the treble it's hard to appreciate it on the T1's. And if you DO eq the treble spike down then this separation gets diminished (in my experience).
Quality - the T1 shares the same general form factor as the T90, etc. The headband isn't leather and while very soft I'd wage it wears down easily. I'd definitely trust the Clears over the T1's in a post-warranty scenario.
All-in-all there isn't anything that the T1's do in particular that would make me feel like I'm giving something up by picking up the Clears. There is a LOT the Clears do that makes them VERY worthwhile, even at the asking price.
To the Clears themselves, wow.
Sitting here listening to them and writing this review I'm still not sure what specific thing it is that I like so much. It's sort of this whole-package experience that just ends up sounding amazing.
I searched my entire music library trying to find the one song they'd buckle on as was often the case with my previous purchases, but not this one. It soldiers through everything and when there is something that sounds off it's down to the source file and not the headphones (there was a lot of file replacing going on in the first 3 days of owning them) these truly are every bit as good as people make them up to be.
The comfort is immense, there was a rainy Saturday here and I think I racked up something like 8 hours of on-head time in one day, zero discomfort and I'd forget they're even on when listening to my favorite albums.
I really do mean I tried everything with these to see if there's SOMETHING they can't do:
Rock (Pink Floyd, RHCP, Queen) - Slow guitars sound amazing, so crisp and detailed absolutely stunning, male vocalists, vocalists in general sound just perfect.
Metal (HammerFall, Avenged Sevenfold, Rammstein, Megadeth, Nightwish, Iron Maiden) - Also amazing, all transitions every riff and every hit of the drum. Especially impressed with Tarja's vocals (forever loyal).
Pop (R.E.M., Travis, Gorillaz, Depeche Mode) - The clarity of the small details is especially amazing, but they're also not too forward like on the T1's or other Beyer phones, something I actually like a lot, sounds more "intended".
Rap (Ice Cube, Cypress Hill, Eminem, Mattafix) - Surprising amount of bass where it needs to be, but doesn't bleed over, very behaved and overall a really really nice experience.
Synthwave (DWTD, Droid Bishop, Furi OST, Thomas Barrandon) - Probably the thing that surprised me the most, it handles the sharp sounds so well I could recommend them just on the performance in this genre.
Instrumental/Orchestral (Movie/Game soundtracks, NieR: Automata OST) - Again just so precise and soft vocals are incredibly sublime, perfect in every way to my ears.
Trance (OceanLab, other vocal trance tracks) - This headphone really loves vocals and with the other mentioned strengths they perform perfectly here as well.
J-Pop (various anime openings and soundtracks) - Usually the flaw of any headphone, due to the busyness of these songs and usually very bright recordings (absolutely un-listenable on the T1's) but to my surprise even here they keep their shine and clarity, the only time I feel fatigue listening to this genre is if the volume is too high or if the track is way too busy. But there's never any distortion. Female vocalists sound REALLY good on these headphones as mentioned before.
The more I listen to them the more I like them, it's like every day I find something else I really like about them and it's been a joy to listen to and own them. They look, feel and sound premium. Its a steep price to be sure but I don't feel as if I spent a lot on nothing (definitely had this feeling with the T1). I did end up making a little headband cover out of some leather I had lying around, no idea if they do stain or not, but I'd rather not live to see it happen.
The warranty thing going on, apparently it is 5 years even though the site isn't updated, sites not being updated is something very very common, especially for brands that generally do their business face to face. Currently when you register a headphone it still says 2 years but I asked my dealer and it is 5.
They have the highest recommendation I can give with my experience.
