I'm basically asking the question above. The reason for this is that I just got a pair of Sennheiser HD 439's and after looking into headphone amps I decided it would be best for me to get one.
However, i want to ask if they differ in quality because I was thinking of getting the Fiio E06 but after rummaging through the attic I found some audio equipment that was left to me by my father, including what turned out to be the internals of a small headphone amp complete with his notes for what goes where.
It won't be a difficult task to get it up and running and I may even make it its own enclosure. But again, will the fiio offer better quality or will they just both do the same, after all, they both amplify and using common sense there shouldn't be any quality difference.
Thanks in advance :)
