^ Er, I wouldn't call my SR-009 review "scathing" and if that's how you took it, then I clearly have to explain further. Most of the reviews I write are attempts at balanced counter-opinions (because nothing is perfect—I operate from the assumption that just about everything is subjectively flawed in some way), while "scathing" for me would be more like my review of the HiFiMan HE-400 where I had very few positive things to say about it. The SR-009 is a very good headphone by any consideration, and I was comparing it to the OII MKI, which for me was the closest ever that got to sonic perfection (but still missed the 100% mark in some key areas). If I'd compared the SR-009 to something like the HD800 on the GS-X, the review would've reflected way more positively in its favor.
I heard the Qualia balanced on a GS-X (MK1), and on that amp I found it to have 100% treble perfection—it was perfectly sharp & pristine, way more than any other headphones I heard before or since. It also had a completely open & holographic soundstage, more than even the HD800's. Relative to the SR-009, I'd call the Qualia thinner-sounding with more treble and less bass quantity, with quite a boost in the spatials as well. To that point, if there was ever a headphone practically designed for the spatial needs of ambient electronica, the Qualia would have to be it. (Global Communication was simply astounding on it.)
If you can get a small headband the fit issues would be minimized, but if you got a medium or large you can do what I call the "sponge mod" (try Google for a pic of it).
