I'm going to wait till I have a chance to hear them myself for a couple of hours with a range of music. From communicating with some people I trust I'm told they're even brighter than the SR-Omega, and in that case I wouldn't be able to tolerate them as the SR-Omega still push those boundaries fairly close to my limit. Also there are some HE90-esque colorations in the SR-Omega that I like (blown out soundstage, nice midbass, etc). But if I like the 009 more then sure they'll be something I consider.
I still think the O2 mk1 are my reference for neutral on a good amp.
HPA- would you mind writing up a detailed thought on the BH vs the Zana Deux? Maybe throw in those speakers in the mix as well (they look really sweet)?
