For some reason, I'm preferring the sound of the HD600's out of my Xperia Z, rather than my FiiO E10?
I've noticed a few things:
On the FiiO E10, some instruments, back singers (don't know what they're called haha), and other small details are less pronounced and almost absent.
On the Xperia Z, the detail is on par with the E10, however during fast, intensive songs you can clearly hear the phone struggle (hear bits of static here and there).
How is this possible?
