^ It's not just cymbals James, it's also acoustic instruments such as the piano, guitar, upright bass, as well as drums. As Anaxilus commented, decay, resonance, and I'll add the natural timbre of these instruments, just don't sound as true to life to me through balanced armature phones when compared to their dynamic driver counterparts. I'm prepared to forego the reproduction of almost inaudible details and remarkable instrument separation that the best balanced armature phones can deliver, for the more organic and visceral presentation of a very good dynamic driver earphone. The problem that I continue to have with dynamic driver earphones is that the bass presentation is usually lacking control, but I guess you can't have everything; not yet anyway.
The e-Q7 still interests me because of its moving armature design, which appears to share sonic characteristics with both balanced armature and dynamic driver phones. By the way, how does its clarity compare to the SM3 as you hear it? I haven't ruled out the FX700 either, although I remain wary of its highs after my experience with the FX500. However, I have ruled out the SM3 for the reasons that I have already given and your description of its sound presentation lends weight to my decision. Of course I'd still very much like to hear the SM3 for myself as that's the only way to know for sure, but I'm not prepared to shell out the better part of $400 for the privilege.
