Well I received my FiiO7 headphone amplifier today. I appear to be missing something though. I bought these because my ears cannot tolerate IEMs and the larger cans I use with my mp3 player don't play my older songs, ripped from my CDs loud enough. Newer stuff (that's so poorly recorded and amplified beyond belief) is loud enough but even with my player maxed out, some of those old '70's CDs from Aerosmith, Zep, things like that just aren't getting it done. So I ordered the E7 amplifier after reading a few articles here.
Trouble is, this unit does not seem to amplify much of anything. When I push the volume all the up to 60 it get's slight louder than going straight into the source. Apparently I'm not quite understanding this unit as an amplifier as it seems to amplify very little. I'm inclined to return the until as defective since it clearly is not amplifying.
