Interesting that Uncle Jesse's look like my new ones, and my old graph looks like the other owner's replacement graph. But while they seem to group in a few basic variations, there is a pretty wide disparity in these graphs, which is surprising, assuming the tests are all done on the same equipment. There apparently is some craftsmanship involved in building these headphones, whether in building the parts or assembling them, which is causing variations in the units. Given the groups, it could be that there are 2 or 3 people building the parts or the units, and each person has their own processes or techniques, which leads the units they build to sound a certain way, slightly different than the others.
Or else these are just some kid's random scribbles that Audeze sends out to entertain us and mess with our heads... but that's what headphones are supposed to do, right?
