Wow! Nice! Are you using T2 PSU for the KGST?

Stax adds thin Mylar spacers to increase the spacer thickness in an SR007 MK2. I'm pretty sure that they do the same on SR009.

I bought a pair of SR009 a few months ago, and I noticed that the phones weren't as sensitive as the pair I heard when they first came out. I think Stax might have increased the spacer thickness just a little.

Happy Birthday!

Oh, I'm sorry. I didn't know that they're hybrid headphones. I'm not sure how to make them sing together now.

I have no idea. But, I think you can convert them into electrostatic.

I like 3 microns Mylar, but anything from 1 to 3 microns should sound wonderful. You'll have to give them a few trials and errors on diaphragm tension before you are happy with the sound though. By the way, those drivers look nice. What is the inner diameter of the spacer holding the diaphragm?

Electret drivers use different diaphragm from electrostatic. Coating them with what you use on electrostaic won't help.

Beautiful!

Wow!

Nice work!!!

If blowing compressed air solved the problem, I'm afraid that the dust cover could have already been broken.

Yea, the dust cover is too fragile to withstand compressed air.

Very nice!

Nice!

Yea, their cable looks pretty nice.

What I really don't like on the KS headphone is its opening area at the back that is too little. It might just sound better if they completely take out the back perforated aluminum cover.

Nice!!!

Very nice!

Good idea!

Nice!

Wow! What woods are those black ones?

Thank you sir!

Nice going.

When I look at the back cover of 4070 the first thing that comes to mind is the cover of a butter plate.
