I'm thinking of buying the HE400's, but reading this thread, it looks relatively new: http://www.head-fi.org/t/586885/new-hifiman-headphone-he-400-is-out I plan on pairing up the HE400 with a Fiio E11 portable amplifier. Good combination? Or should I pick a better amp? I've got a laptop that I bring to the office and home everyday. I code and occassionally like to listen to music to keep me going through the day. So I am pretty much on the go all the time. My music genre: classical, house, deep house, hiphop. And the occasional alternative rock.
