Gonna have to disagree with you there. :tongue: After hearing, for an extensive time (borrowed from friends/associates for weeks which is really the only way to test gear imo: over time and in different "music moods" with a lot of material in a lot of genres in one's own home on their own system away from distractions and hurried/frenzied switching which takes place at other's homes and in audio shops) the RS1i, RS2i, and PS500, I gave up on Grados (for me). Those 3 models just sounded like gloried 225i's (which I have); not substantially different, just more refined. And since the house sound of Grados "fun-fi" only works for a limited number of genres (due to their over emphasized low-mid bass hump and sometimes grainy/harsh treble) it is not what I'm personally looking for. I'd never recommend any Grado, at least, for an "all rounder" unless someone just wants a cheap (sub $100) can (which the 60's and 80's are still good choices) who doesn't care much about SQ, or at least the sound being balanced/neutral/etc.
