Yes, that is definitely the case with the Utopias. You get that sparkle and crunch with the Utopias but after about half an hour, I usually turn down the volume to tolerate it for longer listening sessions. The Abyss, on the other hand, presents even more detail than Utopia, but also has a really huge sound stage so all that detail is so nice and spacey, you really feel like the mix is all around you and it's not fatiguing. The Utopia's detail is much more narrow and right around the head, so I find it fatiguing after a while. I wanted a slightly darker/warmer/laid back headphone in my collection and the E2 seems to be doing that job nicely.
I use Shures instead of Sennheisers as my mid-fi pair, for the closed back bass. Their sound stage is comparable to that of the Clears, at a much lower price point. The level of detail available with Focals makes them all worth what they cost, to me (though I didn't want to spend as much as what the Utopias cost). I will be looking for a warmer pair soon as well to supplement them (because, after all, why should any metal driver not sound cold?). The Audezes I found all had wider sound stages, but those have their own set of issues (like the LCD-X being heavy enough to give me back problems). The E 2 will highlight that problem, all the more.
Abyss had clearly set out to make the world's best headphone, with that model you have.
It would be nice if there was a one size fits all headphone that works well with every piece of music, but as long as there are dark recordings and shouty recording, and brassy recordings, I will continue to prefer owning more than one pair. If only HiFiMan would improve their reliability.
