Have a look at the meier amps, the Aria lets me listen to my MS2i for hours on end without listening fatigue - something that I really appreciate. Prior to the Aria, the MS2i sound just got too much for the ears after half hour listening.

Oh yeah.. the toe tapping/head banging still happens with the CORDA

I don't have a lot of experience with amps, however, if you have an oppertunity to test drive the grado RA-1 give it a try. I have the HG model for my 325i. Don't listen to what others say about it, decide for yourself. After all it's made by Grado to drive their phones, logic says they wouldn't make a sucky amp.
