I still to this day own my pair of SR-80's (so maybe my opinion is a tad void because you are looking at higher end models). Grado has a great sound. Fairly easy to drive, and it really makes rock music come alive. As said before, buy a pair. If you don't like them, sell em here on head-fi. You'll get most of your money back, and then can try something else. No one headphone will please everyone. It's a matter of trial and error. That being said, Grado's are a good start.
