Ok...I had an interesting morning. It isn't every day that one takes apart HE90 drivers. Sorry no picks as I was too freaked out while handling something so delicate and well...fucking unobtainium.
These were from the original production run so they needed some cleaning and one driver was imbalanced. Let's discuss how they were made... First of, the actual stators are indeed glass with gold deposits on them. The connections to them couldn't be soldered so they have adapter plates on them which hold the dust covers in place. The diaphragm is held in place with aluminum spacers and they are actually not glued together so access is excellent. Be warned though that there are small plastic spacers all over the fucking place so I'd advise against opening these up. The diaphragms are indeed not gold plated and they have a lot of tension on them.
Now for the imbalance, the offending driver had the diaphragms completely fused into one of the stators. It had been this way for a while as the hole pattern of the driver was imprinted onto the plastic film. I slowly peeled them apart and recoated the diaphragm on both sides and now they work perfectly.
There was a small hole where the drivers had arced through but it has very little impact on the performance. Small amount of noise from time to time but nothing as bad as an old Lambda Signature.
The other driver might need a new coating as well as it seems to have some charge migration issues so that will be easy to sort out.
Thanks guys. It wasn't terrible but given that I was going to be sitting in grandstands at the Olympic trials, and because life is short, I took Imodium to resolve the situation. TMI, I know, but I bounced back into proper form and ate completely inappropriate foods for dinner.
Thus, I give you Chicken and Doughnuts: beer and buttermilk brined chicken strips with sweet and smokey doughnut holes served with Sriracha maple dipping sauce. Pretty tasty along with some excellent beer at Bier Stein in Eugene.
For me, Fresh Fruit... will always be the crown of the DK album stable.....
Listening now: Bat For Lashes - The Bride. So far, pretty good, though perhaps not quite as good as her last.
When I was in 8th grade, I was generally listening to whatever was on the radio. Someone loaned me this tape and it profoundly changed my life. Whether for nostalgia reasons, or because I actually think it's good, it remains about my favorite album.
Birgir, if you have a chance, could you please make the dimension measurement? I really wonder if the glass can outperform the PCB. I can make a set of drivers for you to try.

"Stepping down from Top Gear. Gave it my best shot but sometimes that's not enough. The team are beyond brilliant, I wish them all the best." -- Chris Evans on Twitter.
That race had a little of everything.
I really enjoyed the way the rain kept threatening with a few sprinkles every few laps. If you missed qualifying, there was a mad scramble for slicks with just a couple of minutes to spare. Mad house!
And there's something satisfying when a team principle (who's usually completely under control) loses it in front of the camera. Wolfe seems like a cool guy though.
I'm almost at the point that I feel sorry for the guys at Ferrari. It seems like whatever they do, it's the wrong move. I was pretty pissed at them for a while, now I can only scratch my head and wonder.
And Kvyat's death spiral is shocking. It's almost like Max stole Dany's monkey's paw or something! Crazy stuff.
I will admit, I got a bit excited when Slash had a long Godfather Theme riff right into Sweet Child of Mine. Some of the best guitar playing I have ever seen live.
