If the STF-2 was the one I heard, it's a good choice for movies. For music I remain skeptical because it just didn't blend like the 400. I kept getting confused as to whether I should listen to bass or the rest of the music. It was that noticeable. But like Rick said before, maybe Jason and I just didn't have it set right. But the 400 blended in right off the bat from what I can remember.
