Burned, yet again, by Mac OS auto-correction 
I own the GS1000i, I think the V shaped soundstage, need for amp and need for long burn-in makes them more finnicky than other Grados
I think the bottom review isn't bad and better than most I've seen:

Key points for me are that the V shape makes it easier to listen at low levels, the ultra smooth sounds and sheer range make a lot of junk sound amazing, not for dark neutral sennheiser listeners. I prefer the GS1000i's since they not only have the powerful Grado live concert experience, but they're not adjusted for being more palatable or balanced >=] an antique wooden violin isn't as sonically perfect as a metal or digitally created sound but has a live feeling you can't get from others.
The build quality is crazy and no two are the same like all classic Grados of course ^_^
Thanks for listening to my 2 cents

That's an interesting review...thanks for posting. It actually mirrors my own experience with these phones, cause at first I felt the PS500s were clearly better. That gap narrowed with more hours put on the phones, so maybe there is in fact a break in effect that came into play. I haven't experienced much of this "nasal" quality that he described, but other than that I'd say his review is spot on. We both reached the same conclusion, that this headphone is a keeper for life, for sure.
