Thanks for the review. I have had exactly the same reaction when comparing Stax headphones (007, 007mk2.5, 007mk1, 507): the 009 was head and shoulders above all of them in the exact way you describe. However, I am not sure any more the gap is that big. The new pads on my 007 mk1 made wonders, especially with the treble of the 007, and the soundstage width. It is not the slightestly tiny bit rolled off any more, but it's not etched either in any way, and it's better defined treble than the 009, which has a kind of light haze quality to it with Stax amps (perhaps cleared by the BHSE).
I may have an opportunity to compare with a 009 in 3 weeks time, then I could tell more. I also struggle with the same thing about the 009: I've always felt the 007 could sound better, and they do now, but the 009 is still out there, and how good potential _that_one_ might have? My wife is more tolerant with my hi-fi bug (and my headphones obsession is nothing compared to my speakers obsession), but she would say we should rather use the 009 money to go spend some time together in a nice place :). And she's probably right, as always, hadn't it been for the 009... :)
But if you are interested in getting the treble right with 007, it only costs you a little DIY by changing the pad foam to another one cut out from the active carbon filter (available in hardware stores as filter set for e.g. Vallox ventilation machines), and use it without the spring, and optionally without the cloth grill (much easier to assemble, too). For improved sound stage, follow the full mod described in http://www.head-fi.org/t/677809/the-stax-thread-iii/2310#post_10536905, which makes the inner opening bigger.
Since you are also in EU, I could even send you my current pads if you promise I'll get them back :), to try them out and do the comparison with the 009. Looks like I can trust your judgement as well as mine. The question is not whether is it becoming better than the 009, since it will be still different, but how close does it get.
I think it was Asr how said earlier as a compliment to the TH900 that the 007 mk1 is about 5% better than a well driven TH900 (both in stock form), but having both (with modified ear pads) I can say the difference is more than that, and although IMHO the modded TH900 is currently the best dynamic headphone, but is still bested by my 007 especially in the treble and sound stage, exactly where you find the stock 007 lacking.
