Wow! That looks so much better than mine. Plexiglass can't stand the heat from solder gun, I think. I use bakelite though. Teflon is nice, but will it grip to the pins well?

I stretch a larger piece of Mylar that is enough for making a pair at one time, and they seem to match one and the other well. And yes, I still do the sound checking by knocking them against the table.

Is there any opening at all at the back? The damping material looks to be quite thick.

Tensioning of diaphragms plays a very critical role here. In my opinion, it's even more critical than making the stators exactly the same as HE90 or Omega 1.

No problem! Please PM me your address and I'll gladly send the phones to you.

Hi Arnuad, I have an idea that I would make the the driver's width a little smaller and increase its length just a little so that the total drive area is the same. What I've found when making the previous pair is that I can't tension the diaphragm just enough so that it has good bass and good stability. At the end, I have to put a little more tension on the diaphragm and add extra 0.1 mm spacers to make it stable. I think the main problem is that the driver is just too large for 0.5 mm spacer. By decreasing the width I mean to reduce it only by about 2 mm. This 2 mm can make a big difference in stability of the diaphragm, I think. I'll also try to incorporate a big hole in the center of the driver similar to Stax SR009. Let's see if it helps with the stability issue. About the Float clone that is with you now, I'm puzzle to hear that you find it so much different than the last time it's with you. All I did before sending them back to you was to clean them and reglued the front cloth. The headphones require a muscular amplifier though. They sound pretty good with my KGSSHV and DIY T2.

Thanks Kevin. I made the male jack by myself since I can't find any good ones around. I have to sacrifice 2 pieces of XLR male jacks to make one Stax jack. I take out the pins and put them on my CNC drilled bakelite piece, epoxy them, and put them in the XLR jack frame.

Thanks guys! I'm just making them for fun. A big thank to Tyll for making the measurement and review. Now that I'm all pumpped up, just wait and see my new version of Float style headphones.

Indeed, I did. And they sound pretty good too.

Wow! Nice!

Show us pictures please.

That would be super, super cool.

Any chance for a GB on PCB?

Very, very nice indeed!!! Sent from my iPhone using Tapatalk

That's the spirit.

Will you redo the silkscreening of all the letters in the front panel? Looking forward to seeing the finished amp. Wachara C.

Ceramic sockets are way cheaper than Teflon.

Nice, Birgir! Wachara C.

Nice!

Glad to hear that you've fixed your headphones, Defcon. Wachara C.

That's just beautiful!

Happy Birthday!

Those amps look nice!
