i have a pair of the original 400's and really like them, but they are pain to push. at work i have a sony pha-1 that is one of the few dac/amp combos that will bypass any apple on-device dac. it also pushes the hifimans very well and sounds great. sits well on the desk, and has a rechargeable battery for on the go. should be able to find one around $200, the dac will be an upgrade to whatever device you are plugged into.
