I have the x10 paired with my Creative Zen Vision M right now. I'm debating if i should get an amp because when i have the volume pretty low 4-7 out of 20, i don't really get a feeling of the bass, with it sounding more like a mid range bump. Do i need an amp? Or is this maybe just because the volume isn't high enough for it to push out what i'm looking for?

I was thinking about the Nuforce mobile or the Fiio E3, not much money to spend right now. Kind of on the low side after those x10s.
