Regarding the HE-400, the older version with the white drivers was a lot better than what replaced it. Unlike the later HE-400, it was not bright at all; in fact its tonal balance was kind of like the SR-007 mk1. It was lacking on the technical front (had a grainy sound with grey background), but its bass performance was among the best of the HiFiMans and it performed well overall for the asking price IMO. Too bad subsequent revisions were changed.
