So beautiful!

I think you've stretched the diaphragms too much.

These are my measurements: I also don’t really know how to read them. However, my headphones’ graphs show pretty similar patterns to the Stax’s 007 MK1’s. Your headphones’ graph is so flat. Maybe you should retest them again. How is your bass compared to the 009S?

Very nice!

Believe me; soon you'll prefer your DIY phones "sonically" over Stax.

Your arcs and headband look exceptional. Very nicely done! Are they 3D printed? What material do you use?

Do you notice that with the new stators you've made, the phones sound less bright?

😀 It’s nice to see you already get hooked into making the headphones. I’m sure you’ll figure out what is wrong. What spacer thickness do you use?

Very nice!

I believe the 580V Stax bias voltage with 5M ballast resistor is safe for HE90. I have tried the HE90 with some Stax amps in the past, and I didn't notice any problem. However, if it will make you feel better, reducing the bias voltage to 500V and adding additional 5M ballast resistor are the way to go.

Waiting for your coming to see me.

Nice! Is the property of your film any different than a typical Mylar film?

Hi Aumkar, Wow, 0.45 mm D/S distance is nice. How big is your diaphragm? Wachara C.

The driver looks very well built. I'll get a pair too.

@mwl168I do not need the mini T2 boards as I've got some already. Thanks for putting me in for those PS boards though.
