I'd go download Easy CD-DA extractor, and re rip all of your CDs to at least 192 kb/s minimum MP3 VBR using the LAME encoder. I did this and everything sounded better, even using the same old headphones and speakers. Much more dynamic range, no more flatness.

I'd also second the recomendations for new headphones. Go for the Westone UM1 if you want in-ears, or some Sennheisers, AKGs, or the Koss portaPro if you want full sized, but non fatiguing headphones.
