I wasn't a huge fan of the ps500, it's cool but there are other headphones that do the bass heavy, recessed mids sound better like the DT990 or X1. The pS500 sounds a bit "messy" and conjested and is not really a grado when it comes to its sound signature.
Neither the RS2 or PS500 will give you a wide soundstage although that can be improved by switching to G cushions. But that has its drawbacks too.
I would recommend the RS2 or the RS1 if you can swing it. I'd also consider the 325is over the ps500.
If you must have a wide soundstage the GS1000 and PS1000 are your best options unless you like the sound of other grados with the G pads. I guess it's cheaper to try the pad options first though
