Ahw, it's a shame you sold your RS1i.
It's ok, since I've always thought that choosing between Grados from the 325s upward is a matter of taste... I liked my RS1i a lot but it didn't play Metal as good as the 325is. As I have a family now the joys of high-ranged gears cannot feel as complete as before, too. But all in all I do like my 325e a lot. Definitely the single best price/performance headphone I've purchased.
