Couldn't think of a better way to put my question, and thought vague would be worse.
I have the Sansa Clip+, and I'm using the FiiO E7 (with the included 3.5 to 3.5 interconnect out the headphone jack).
I've had the volume on the Sansa set at max, and then all volume is controlled completely through the amp (as I had the E7 connected to an ipod touch previously, using a LOD).
My question is, is that really the best way? Am I distorting the signal out of the Sansa by having it maxed? I sometimes think I hear something, but it may be in my head (no pun intended).
For reference, the Clip+ is running original FW (I had issues with running Rockbox and reverted).
Can anyone please clarify this for me, or point me in the right direction?
PS - I'm also wondering if upgrading the interconnect would make a difference at this level. I'm using the ATH M-50 to listen, and mostly outdoors - so I doubt it. But it doesn't hurt to ask, right? 
Thank you!
