need a recomendation for headphone amp

The Fiio E7 does a good job with mine. 

I would recommend a used Ray Samuels Audio.  All models work well and have never given me any issues.  Good Luck! 

Fiio has some great value amps.

Don't get the E7 though if you don't need the DAC.

The E11 would be better as a pure amp.  

Though, if your budget is around 150$ try finding something used. 

It sounds like you are looking for a portable amp, so as others have suggested, FiiO makes some quality products. http://www.head-fi.org/forum/thread/566432/wts-fiio-e11 is an E11 for pretty cheap if you don't mind the slight cosmetic blemish.

If you need a DAC, though, the E7 works nicely. The amp isn't as nice as the E11, but with the E7, you can buy an E9 later on if you need a desktop amp and hook the two together for a pretty killer combo at little cost.

Yeah, thats the advantage of getting the E7.
