A bit of advice and information about my sonic preferences.
I’m very treble sensitive due to pretty severe tinnitus. So, I don’t like piercing upper mids or highs. Yet I was very curious about the sound signature of a hyper-detailed headphone like the Elegia, so I took the plunge on the $389 Adorama deal.
The detail of the Elegia is excellent. No doubt. But it comes at a cost. There is some really wonky tuning in the upper mids that just makes them sound metallic and a bit shrill at times. It was a case of “ice pick in the ear drums” piercing like some Beyerdynamics, but it was enough to annoy and fatigue me over time.
I’m also not a huge bass head, but I like to feel some down-low. The Elegia are very deceptive in that regard. Some people say the bass is “thin” or “recessed,” and that can be the case. The bass is present but stays in its place in the mix, with not much sub-bass. But when the bass kicks in a tune, man, the Elegia have a punch and slam that sometimes can feel like air being pushed into your ear in some EDM tracks, for example. It HITS, and then it returns to its hole.
Trying the Elegia made me realize a few things. One, I prefer a more constant sub-bass than recessed bass and sudden slams. Two, my distaste of shrill upper mids and treble is constant. Three, I think I prefer a slight roll-off of treble at the expense of a slight bit of detail to eliminate fatigue.
Maybe that’s why I really enjoy the HD 6XX despite the alleged “Sennheiser veil.” The rolled-off signature at both ends suits me pretty well.
So, I did some research, and the DCA Aeon 2 Closed looked like an ideal match. Found a nice pair with the fenestrated pads from the Aeon 2 Noire used at a very price and went for it.
Well, a blind squirrel found a nut on these, as I love them compared to the Elegia. The sub-bass on the A2C’s is SUBLIME. Always constant, always rich and warm but never overpowering or seeping into the mids. The upper mids and treble are rolled off slightly, so they lack the detail of the Elegia. But they also lack the metallic mids and treble, which is good for me.
My only complaint about the DCA’s is fit, at least for me. Most reviewers indicated it was among the most comfortable headphones they’ve ever tried. Maybe they all have smaller heads than my enormo-dome, as the clamping force on these is higher than my Edition XS, HE-400se or HD 6XX. Combine that will less-dense foam in the padding than I would prefer, and I get a bit of discomfort with my right ear.
But I’m experimenting with positioning and cup height, and the headband hopefully will bend naturally to accommodate my big head.
Sonically, though, the DCA Aeon 2 Closed are an ideal match for me. I listen to a lot of rock and classic rock, and the A2C are MUCH better in those genres than the Elegia. The Elegia reigns supreme with stringed music, vocals, classical, piano jazz. The A2C’s are better with everything else for me.
In a quick summation of the DCA A2C signature, imagine the 6XX on steroids, with everything better except for maybe the mids. And the DCA mids aren’t that much worse than the Sennheiser mids.
Hope this description gives you a little context about the DCA A2C.
Good luck!
