I have started to post impressions here and there so I thought I might start the official report thread.
For those who don't know, Fujiya Avic, a local reseller of new and used AV gear has been organizing these headphone festivals in spring and fall since a few years ago. The thing has grown so big (over 3 thousand people came to the last one) that it was held over two days this time which helped with the overcrowdedness.
With the generosity of Fujiya and help of head-fi member sasaki, we could again have a small room to gather up head-fi crowds coming from tokyo, fukuoka and even as far as the bay area! Jude provided us with a bunch of tshirts, got myself a nice cardinal one this time around ;). We had a pretty good gathering and I missed most of it unfortunately, hopefully I can do better next time.
I will let others do the photo report as I really only took a single picture and it's of little interest to most but cute nevertheless ;)
I had a brief listen to the Stax sr002/srm002 combo yesterday and I liked what I heard a lot!
Granted, I had never listened to baby staxes before so it was mostly a shock of how much stat goodness one can get get for that price. However, I was concerned about these reports about the thin diaphragm / sounding like an omega 2mk2. What I found is that with a proper seal, the bass is just marvelous (more like an omega 2mk1 than mk2 and actually possibly tighter than what I get from my stax amp with the omega 2 mk1. The other nice surprise is that, upon short listen at least, the sound was quite dynamic (reminiscent of my 007A(SZ2)) and fun (foot tapping), while at the same time not tipped up in the highs (e.g closer to an 007mk1 than than my 007A(SZ2) or 009 in that regard). Note that this was using the headphone out from my iphone so maybe one would get bit different impression from a better protable rig.
Overall, I'd say it was shocking good for the price (there are iems priced 3x as much as the combo at the show and I doubt the best multi way ba + crossovers can beat the transparency of a full range, open back, stat driver. I could easily imagine having a rig like that when I am out of town or at least to go around other zillion rigs at fujiya's headphone festivals and sample sources 
.
Only minus is that the ear plugs are probably too big for my tiny ears even though the design is smaller than the previous generation so earpiece would fall after a while without applying pressure or using the metal headband. I only tried the middle size tips, there are also S and L sizes single flange rubber tips in the box. I can't imagine what this could turn out to be with custom silicone molds! It would not be small but again the multi way BA iems are getting pretty large too .
The other item that caught my attention was Mkubota1's AKG K-1000 (original post here: http://www.head-fi.org/t/57805/history-of-the-akg-k1000/60#post_8817119):
Last bit for me is that conversation with Stax: still working on a new amplifier, still needs some time... About the influence of Edifier: there's not been joint development until now (the recent baby stax refresh is still all made in Japan). So, it looks like they've kept their independance, which is pretty cool. Looking into organizing a visit to their office, with an interview that'd be posted on this site, so stay tuned...
That's pretty much it for me, I will let the probably much more interesting reports from others to follow!
Arnaud.
Edit 2012/11/3: The Omega 2 I owned was of type SR007A(SZ2). I bought it in summer 2010, a the same time some 007mk2(SZ3) appeared outside Japan and were coined as mk2.5 with probable change in membrane thickness / increase in brightness.
