I purchased the HD 25 about eight months ago and was wondering how much they benefited from a decent amp/dac. I have been looking into the E17 because it seems like it would be good enough for my desktop and be portable enough that I could take it with me. I also like the E17 because if I ever got a higher quality set of headphones(HD600) I could just plug it into the E9 for even more power. Has anyone used the HD 25s with the E17? How much did the sound improve?
EDIT: I should note that my main two sources will be a desktop PC and a iPhone 4S.
