Is the burn in process Justing is doing working thus far?
I suspect that we're seeing what we are with the HE-400 because of a few reasons.
1) The HE-400 is probably out-selling the other models, due to its price point.
2) The HE-400 discussions on this forum are getting a lot of attention / action, where owners are all chiming in and sharing their experience. Again, due to the numbers of participants, posts, etc., it could seem as though it is a bigger issue than it is.
3) The HE-400, has undergone 3(?) revisions. Actually, I believe # 3 was reverted, so we might be back to two revisions. # 3 was an apparent driver change with the off-white driver enclosure.
4) Finally, HifiMAN doesn't release their issue / return rate statistics, so we don't know if the HE-400 has more flaws, or is on par with the rest of their line.
