I don't believe an amp will improve the bass...and I'm guessing that "improving" means that you want is more bass.
These IEMs respond well to amping, yet the bass quantity will remain the same. You should try a Fiio, which come with a bass boost feature. I also hate to use EQ, but I sometimes use the bass boost of my little Fiio since it is implemented very well. If you are happy with the bass boost on your PC, I'm sure you will enjoy the Fiio with your ipod.
i should have said "more prominent", similar to what my pc had done to it.
i probably will not bother with it, as they are no where close to a basshead IEM. (still love em though)
i did some research, got some advice, more research, settled on Future Sonic's Atrios M5. quite excited about them :P
anyways thanks for the help, i appreciate it! maybe in the future ill look into it more.
