I guess the problem lays in different reference points. I mostly use Stax and IE8, both are extremely smooth, liquid, non aggressive, silky, etc. People who listen mostly to armatures, got used to aggressive sound.
Also (it is different discussion) but i think armature phones don't reproduce treble correctly (all of them). They tend to be either not very resolving on top, or sibilant, and metallic. I'm very allergic to this. e-Q7 is definitely not worst of armatures, but it just not the step up, as I expected it to be.
Regarding soundstage, I guess, we all have different things in mind. I don't think any closed IEM have any soundstage. Phones that have soundstage (in my definition) are: K701, SR-2020, D2000, SR-001, G1A, OK1 (listed in order of soundstage size). IE8 have best amongst IEMs (and they are semi-open). Phones: RE0, ER4P, E-Q7, HFI-780, UM3X have zero soundstage (in my book), or I could say that they have "imaginary" soundstage, if it explains something.
I find the Stax SRS 001 system to be very transparent with very good textural detail. How do you find the E-Q7 to fair in comparison to the baby stax in terms of transparency, realism and depiction of instrumental textures?
I eagerly await your impressions of the FX700.
