I'm not Oteil, but I think it's really difficult to make a definitive statement about whether the difference between RS1i and SR60 is worth the money. There is no doubt at all that the RS1i is "better", and there is also little doubt that if you like the Grado signature you will love the RS1i. But whether the difference is worth that much money? That's got to be down to the individual.
A related question is something like this: do I think a Grado fan who never hears the RS1i is missing something? Yes I do.
Yeah, you killed me with that last sentence, lol. Everybody pretty much says what you've said, so I guess I have no choice but to check them out. Its almost as if from what I've read that there is a thin line between the 80's and the RS1, that has to be listened to for one's self. Thanks for your reply
