Another, semi-random, thought …
Mixed driver technologies in IEMs have been quite a mixed bag when it comes to coherency … although they started to become more interesting/coherent (for me) with the AAW W-900.
The tia Fourté totally threw me off when I first heard them, and it was the better part of a day (or so) of listening before they became coherent for me (not a driver burn-in thing, either).
The Odin have, as far as I can hear, no coherency issues at all, even fresh from the box. They’re extra-ordinarily well integrated. They’re getting, as far as I’ve experienced, the best out of each of their respective technologies (dynamic, balanced-armature and electrostatic drivers), and the best (effectively seamless) integration between them, that I’ve ever heard.
