For me the 007's are a clear step up in every way, much more controlled, actually layered sound stage (which so few headphones can do) and far more resolving. Once you get past a certain point the SR-Omega gets lost and confused. They are still great but yeah, 007's were a big improvement.
I really don't agree about the X9000 bass compared to the 007's, it completely falls flat on its face. Apparent resolution vs. real resolution to me.
