Yeah, I spend far more time on Head-Fi than I'd like...
I thought I would like the e-Q5 too, but I picked up the Grado GR8 and it's kind of peaky. I'm not sure if this is due to Grado's tuning (it probably is) but I've been reading the Grado models are like long-lost brothers to the Ortofon models. If I see a good price on the e-Q5 in the FS section I'll probably jump on it, but there haven't been too many. As it stands the GR07 and the SE530 both come very close to complete satisfaction, with a few flaws in both - the GR07 doesn't flaunt it's detail like Etymotic or the CK10 does, and the sibilance at higher volumes bothers me, while the SE530 is large, bulky, and uncomfortable, and also suffers from the same "too smooth/missing detail" syndrome (but is smoother overall and more balanced).
The CK90Pro also seems interesting, and i've had my eye on it for a while, but the only ones I can find are imported from Japan and quite costly. If it turns out I don't like them I will probably end up losing quite a bit of money on them, and I don't like that at all.
