Yes i mostly agree with that comparison, however my thoughts differ somewhat in some areas. For e.g. i think the Abyss has more presence and size, and is more forward. The HEKv2 does however have a more euphoric and natural tone and presentation.
Quoting from my review, " I don’t think the V1 is good enough to compete head to head with the likes of the Utopia and Abyss in a lot of genres, but the V2 very much does so, whiles retaining the excellent comfort and ease of the sound. " This seems to line up with what's described in the review you posted. I do believe the abyss still holds a substantial lead against the HEKv2 in terms of raw performance, but the HEKv2 did a much better job and even took a genre off of the Abyss for my tastes, i.e. Metal.
IMO the Abyss and Utopia are clearly better than the HEKv2, but they all do different things. I think the HEKv2 is more similar to the Utopia in that respect.
HEKv2 trades blows with both the Utopia and Abyss, but when combined, the only area i see the HEKv2 wining over both is comfort. If you look at my "best at" table, you'll see the HEKv2 taking alot of 2nd places, but no first, because either abyss or utopia is better than it in everything except comfort/long sessions.
So to wrap it up, i use Abyss for what it's the best at, reach for the utopia for what it's best at, and reach for the HEKv2 when i wanna game, study, read, kick back, etc.
If i had to get rid of one of those, it would be the HEKv2, glad i dont though
