ok been throught this alot. First ck out headfi.com That is where you want to be looking. Of what you are looking at the 600 are the best. But also take alot of power that a ipod can't provide to make them sing. You will get much better results if you use a headphone amp with them. If you want a bigger headphone I highly recomend the a-900 I had a set for a while, the bass is easy to drive which is the ipods needs. Also clear and the best bang for the buck just limited distributers in the US. Are you using this at home, work or do you need it portable? What is your price range I can better give you advice.
A headphone amp really makes the ipod sound about 35% better, much more than running uncompressed music, the ipod seems to have a lock up issue with big files.
