It’s funny- I originally thought I would buy the Atticus, but now my Eikon is the “desert island headphone” I adore, even ahead of the Stellia and Auteur (!).
While the mid bass isn’t emphasized with the Eikon, its deep bass can hit
hard, and I think that’s what I enjoy with certain genres, rather than the mid bass. Perhaps that is because great deep bass is harder to reproduce with speakers in a room, or because of my genres preferences- not sure.
Granted, amplification (and to some degree, cabling- in my view, anyway) can have a big impact here. I use a WA2 OTL tube amp, which meshes exceptionally well with ZMFs… and perhaps my current tube choices work especially well with the Eikon. But hey, if I’m musically satisfied, who cares?
