jackangel,
imho, u really should burn ur ety's in for at least another whole 10~20+ hours before u make ur final judgement, if not more. for my pair, the frequencies seemed to smooth out and extend a bit on both ends when i did a comparison between brand new etys and etys after playing a whole day straight of pink noise. the sound became much more involving...
the ety's are not my reference phones... i use my staxes, which imho present a more transparent, realistic, and faithful rendition of the music with a flat frequency response. the ety's, in comparison with the staxes, seem to give me an eensy bit of that grado sound, ie, little bit of extra strength in the mid to upper mid-ranges. it seems like u enjoy this in ur music (i don't really... :| ...), so i see no reason why not to go with etys. also, as for soundstage, imo the etys will give u the soundstage of a pair of $130 open phones. soundstage is present, but it sure ain't vast or anything. it is incredible that it has soundstage to speak of tho, as an ear canal phone: the only canal-phones i've heard that exceed the ety's for soundstage are the stax-001's...
as for bass in etys, for me, bass seemed to firm up a tad after burn-in. however, never was the bass in the ety's particularly powerful. joelongwood still puts it best: the bass is heard, not felt. like, a live gig, bass drum kicks are usually not heard over the rest of the music, but they're present, and u feel them driving the music. with etys tho, u hear it, and it drives the music too, but it's just... different. to be fair, few headphones (and not even too many sub-$1000 speakers) will give u that "felt" bass... surprisingly, i find that now with my upgraded source, my staxes give me good bass... but i digress.
in conclusion, i say burn ur etys in longer. ur return thingie doesn't expire for another month... keep em as long as u can!
