I think the Amperior also scales up pretty well with an amp. When comparing between the Amperior connected to my Ipod Classic and to my Fiio E10, sound is obviously better on the E10. When paired with the Ipod Classic, the sound is kind of congested and lacking depth. Or maybe the Ipod Classic just has bad synergy with the Amperiors, I'm not sure.
