Do Superlux 668bs benefit from an amp?

Hi,

 recently got my Superlux 668Bs and I rly like them. Anyway, is it possible to get even more out of these headphones? What I mean is would amp increase the sound quality for these? If yes, what do you think about FiiO E06 (rly cheap)? Sound volume isn't really a problem here, because for me they are loud enough, but obviously I would like to get even better sound quality if it is possible with an amp.

Well those headphones are only 56 ohms so I don't think an amp would help out very much. I think a DAC would help increase the sound quality. Can you give more details about your audio setup? 

Note: I am no audio expert so hopefully one of the more audio inclined members can help you out more.
