For ES2 owners, how does the ES sound straight out of an i-Pod? I'm considering a purchase of an ES2 but I don't want to carry around a portable amp (I've been there and done that and I just don't want to go there again). All my music was ripped and downloaded using Apple lossless into a 80GB i-Pod video. I'm currently using ER4P's and the sound is good but I'm looking for a little more bass (but not boomy bass) and a tab bit of warmth but not to much. I really like the clarity of the ER4P's and I don't want to stray to far from that sound. Also, although I don't have an issue with the comfort of the 4P, I know a custom would be much better. I'm not unhappy with the 4P, I just want to be happier.
Thanks for any suggestions.
