The OP has stated a clear preference for the Grado sound; bringing the HD650 into it isn't a good idea IMO since you really can't find something more diametrically opposed sonically.
Personally, I like the HD650, but it's not on the same level as the really world-class headphones (HE90, R10, etc...). I don't think this will be a step up from the RS-1, just a step sideways.
However, it will be a different sound signature, so it could be worth experimenting with. In that case, however, I would suggest geting the HD600, as it's more neutral.
