Something I was thinking about and wanted to post: There was a while back that somebody who owned the v4 magnums decided to ditch it for the HE-400. I had the v5 magnum and the HE-400 and the HE-5LE all side by side and I suppose I can see somebody preferring the presentation of the Hifiman headphones but....the difference in detail and clarity between the Magnum V5 and the Hifiman headphones was just too much to ignore. If on a scale of 1 to 10 for detail the Magnum V5 is a 10, then the HE-400 is a 6.0 and the HE-5LE is a 7.5. The HE-5LE was a noticeable upgrade in the clarity department from the HE-400 but the Magnum trumps them both hands down here. I'd like to throw this out there for people who are wondering where the Symphones Magnum stands in comparison to other headphones.
The only headphone I have heard with as much or perhaps better detail than the Magnum V5 is the HD800.
