Hmm, not sure I can go along with that. The unmodded HE-500 has some significant problems. Subjectively there's a dark, echoey effect typical of ringing. I'm not the only one to complain about it. I've now had two HE-500s and found them similarly afflicted. It's certainly an effect I could not live with. Also the HE-500 has a very audible treble suckout which leads to the peculiar effect of dullness and sharpness all at the same time (this with the pleather earpads. The velours were too uncomfortable). The only ways in which I felt the HE-500 was superior to the 880 was a greater smoothness--less grain--and of course more extended bass. But then I listen exclusively to classical, and bass is not that important to me.
I don't defend the 990. I've never heard it. The 880, however, is quite astonishingly neutral and free of oddities once its treble peak is ameliorated. Yes, I wish it had the grainlessness of the HE-500, but the compromises are too great for me.
Plus the HE-500 is like a brick on your head. My neck muscles eventually called Uncle.
