So I've been using these three headphone sets plugged into my Creative X-Fi Go! external soundcard/DAC. Thus far I have been fairly impressed with the results; there is no shortage of volume. What I have been wondering about is how a headphone amp might improve other audio properties/qualities. And to be honest, I don't know; I'm just curious.
Perhaps someone here who's had experience with these sets can advise?
FYI, I am thinking of expanding my headphone collection in the near future, possibly picking up the Beyerdynamic DT 770 Pros (80 ohms) or the AKG K240s / Sony MDR-V6s (been struggling to get advice on these in the headphone forum).
Anyway, assistance with my question about an amp would be appreciated.
