I did some skimming around and saw two headphones that stuck out to me: Denon D600 and HiFiMan HE-400. The D600 I can get for ~$230 and the HE-400 I can get for $300-400. I heard there are multiple revisions of the HE-400. Which ones would I get if I ordered brand new from HiFiMan/Amazon? If I got it used, which ones should I look for as well?
