I'll throw a wildcard into the running: the Koss ESP950. As far as budget stats go I don't think that you'd find Lambdas (Stax 404, 307, etc.) neutral, but they are quite good if you're ok with the mid hump and a lack of extension in the lowest octave.HE-500 is probably the most reasonable compromise, best of the current HiFiman lineup anyway. The Paradox is more neutral, though as Marv said it has some extra energy in a portion of the treble.The HP50 is not neutral. I really like it, but it is definitely more of a fun sounding headphone with extra bass and a wonky upper midrange.
Whoops, ninja'd while I was editing my post. I added a few more recommendations to the post up there before you responded.The Abyss and Jecklin Float QA are my current reference headphones. You mentioned bass performance in another thread. No headphone I've heard has better lower-end response than the Abyss. It comes closest to speakers (without the obvious physical power that a big woofer has).
I am having the same opinion about HP50
Quote from: Darth Obvious on March 02, 2014, 11:07:56 PMI am having the same opinion about HP50 The HP50 measurements would seem to indicate otherwise but no. They just don't sound right to me. I hear a nasal-ness or honk which doesn't jive with any of the measurements that I have seen. In fact, I found the Monster Dre. Beats Studio to sound more tonally right than the HP50.ESP950 yes - except for bass roll off.
Thank you for the post... So what are your favourite headphones at the moment?
