I have to say that I'm a little concerned about Beyer build quality lately. As an example, I removed the pad from a friend's DT 1350 and noticed that the meshed material protecting the driver wasn't properly glued on one side.
I also noticed quite a lot of small manufacturing defects on my former two T50p and our own DT 1350s. Not that it influences sound quality, but it definitely feels that they were made in a rush.
Finally Tylll has measured several beyers and some of them had reversed polarity. Again, it's likely not to affect sound quality, but it screams inconsistency. In addition all the Tesla Beyers measured differently : the two T1, T5p and T50p aren't measuring in the same way, while the DT880 do, and as a contrasting example the K701 and LCD-2 seem to remain quite identical across models.
I think it would be nice for Beyer to give some explanation, at least for their flagship. As someone said, that kind of money isn't exactly cheap.
