Also, are there any sub 50$ headphone amps which would benefit clarity at all if not the Fiio?

The Nexus doesn't get very loud so an amp helps a lot. The FiiO E11 is only $53 on Amazon and it's FiiO's flagship amp. I use the E17 with my M-100 and they do improve clarity and sound stage.
Edit: Sorry. The E12 is FiiO's flagship. But the E11 is still a great amp and has a good reputation here on Head-Fi.
The e6 will make it louder, no doubt, though you loose the ability to use an eq (other than the e6's) and the sound doesn't go THAT much louder.
The e11 would be better.
If you want an amp (no dac) the answer is always going to be E11 a fantastic amp for the price especially with it's bass boost options (not that you'll need them but who knows) I used to have one and it never let me down once, and it's not bulky. If you want sizable improvement then i'd say get a dac amp combo maybe the E17 or E07K. I have the E07K setup on my dell laptop and my M100's sound better then they do when using them with my HTC One X+ or new Nexus 7.
