In that case he should get the Grados. They work very well with rock music. It's just the same sound as when you turn on a "rock" EQ preset on a mp3 player.
A warm setup. I can listen to my 325i's (which some claim are the brightest of the bunch) for hours with no issues. Maybe I am a treblehead...I don't know. I just know what sounds good to my ears and that is Grado on tubes. The OP also stated he likes treble more than bass. Sounds like Grado is a good match for what he is looking for. If not, sell them off/return them and try again.
