@msstl Interesting analysis. Thanks for doing it. Explains a lot. Because this movement starts so softly, my tendency was to begin listening at around 80db, which meant--because of the extreme dynamic range--by the time I hit the peaked highs I was pushing 100db, when I would hear the snap. And, again, this snap comes at the peak of the highs not during any of the drum rolls or beats.
@ozzy62 As I mentioned, it seems that I can play my system at a sustained 95db. It is just when there is a peak beyond that coming from a sustained and building wall of sound that I get the snap. Still, you would think the Z2's could handle this. I posted my experience thinking that other folks with ribbon tweeters had encountered similar issues.
