FWIR(From what I've Read, a common acronym used on head-fi) I'd recommend the Audio Technica M50's They supposedly have very good, tight, punchy bass Also, instead of a sterile sounding noise, it's "warm" and nice to listen to People are raving and giving incredible reviews on these cans...

Thanks a lot for this thread! I just pulled the trigger on these headphones about 5 days ago, and I'm waiting for them in the mail. I was also thinking about looking into some cheap amps but from the replies here i'm guessing i dont need one. Sucks that u cant get a pouch, i got mine on ebay...
