Yes it is expansive, a big step up from the Aeon 1.
The soundstage is more upfront and to the sides than to the back, it depends on the track but i hear it definitely wide outside of my head (with techno mangling my head atm.).
It creates a coherent image of a stage where sounds and their sources are all placed well separeted in their clearly "visible" spot.
It never feels confined in any way - like the AFO, which could sometimes almost sound to cozy.
I would say it is has the perfect size to present music as intended at realistic size - I see my self sitting in an auditorium a few rows up with a nice view of the band, not
to close not to far.
Then again it depends on the recording and how much space the engineers "gave" the recording, the AFO 2 simply adapts.
Thanks to its speed, detail and timbre it presents (good) live recordings like The Who's "Live at Leeds" or "Deep Purples "Made in Japan" almost as hauntingly realistic as the Ether 2, almost...
I'm liking these cans more and more, almost developing a crush while revisiting my favorites.
