I was looking for the same info and found this post. I just came from a local headphone store and tried the Momentums with whichever amps they had in store with my iPod mini. There weren't many choices: Fiio E6, E11, E12, NuForce MMP, JDS C5. The only amp that mad a distinct difference was the C5...but even more so after I used a Fiio LOD (L3 or L9). More clarity and liveliness.
