I tried the RS1's and was NOT a fan. Just treble cannons, no low end to speak of (to ME). The PS line was definitely a lot better, although it felt like there was a sharp bass dropoff under ~80Hz.
Admittedly I'm coming from M100's so we're talking mid-recessed into mid-prominent, so that's a real shock to the ears. Curious to try the GS1000i though, reviews sound promising.
If you thought the RS1's were treble canons....I hate to say it....but Grado's more than likely are not going to be for you.
Maybe...the PS500......maybe
