I spent a fair bit of time with the Utopia at the audio show yesterday, definitely the most fun I've had since listening to your PS-1 setup back in the day. Punchy as hell and it just doesn't compress or soften even if I played very dynamic music way louder than I'd usually listen. Pretty much everything I've heard other than my LCD-XC and the RS-1/PS-1 will soften & compress to some extent, my Senn 580 and AKG K340 do it, and so did the Focal Clear I tried out yesterday. My first impression of the Utopia was that Focal took an RS-1, fixed up the treble tizz and bass, and then just cranked everything to 11.
I can also see where @EdipisReks1 is coming from regarding the soundstage & placement, it's definitely more of a Grado soundstage than my LCD-XC or K340. Audezes are the best I've heard so far at creating a believable sound field, that is, not only placing voices & instruments in the correct place, but also getting them to project properly. For instance, a timpani will make a sphere of sound whereas a trumpet will make a cone of sound, most headphones I've heard will make both of them into a ball-ish shape. The Utopia has a sizably smaller soundstage than my LCD-XC and at times it did feel a bit cramped like there wasn't quite enough space for all the instruments & voices to breathe & project properly. I get why an audio engineer wouldn't want to use these for mixing.
Overall, I think it's the best dynamic headphone I've heard so far. If I hadn't heard Audezes I don't think I'd have any real complaints on the Utopia. This is definitely another headphone which I need to hear in a quiet room to hear what it can really do.
