Uhhh, sarcasm? (In my post, to be clear.) BTW, I like DMS (even though they are apparently buddies, he's like the anti-Zeos, and I mean that as a compliment; his reviews are concise, detailed, and specific), but I didn't care for this particular video much. And FWIW, I believe DMS works for Abyss, though it has little to do with his reviews--given their prices, almost nothing he reviews really competes with them.
Personally, I wish I had the resources to get (or at least audition) the Abyss headphones. I have little doubt that they are great, though obviously not close to four times as good as an Aeolus ($5k vs $1.2K). I understand the principle of complementary headphones (and practice it myself; I'm thinking of a new pair this spring and am leaning to something very different from the Aeolus like the closed DCA Noire), but in practice I tend to ignore it. Although I have a few pretty good pairs of headphones, I rarely use anything but the Aeolus for music listening. But I watch a lot of streaming TV and movies and do switch off more for that. More often than not, I use the Sennheiser HD700 (which I never use for music any more) because its wide sound stage is immersive and it's easily the most comfortable headphone I've ever worn (I watch for hours). But for a lot of movies, especially modern action movies, I lean to the Focal Elex because of its punchy dynamics. And if the movie is music heavy, I go for the Aeolus.
