  1. That is really sad true - they are doing little progress or even backward lately but prices always go significant higher
  2. Your link to the image doesn't work 😞 Can you just paste it here, please?
  3. Thin membrane is not everything in electrostatic world. So I would love to hear them before making any judgment. Good news they didn't try to develop their own plug's standard and used well known Stax style. It would be also nice if their new headphones would kick Stax to start developing something better and new more quickly before I die .....
  4. Could you share more pics and a little bigger (that last is terrible small) ?
  5. Thanks a lot for your efforts Todd !!!
  6. I understand that it was new but was it version from the new production with small case and two different cables, or the older one that was sitting somewhere on the shelf?
  7. My mistake, there are no output capacitors, but series resistors should be placed with output that is coming from those big red resistors. For each channel two resistors are needed, just like on this example schematic, where I marked them. If you are not familiar with electronics it should be easy to do for any DIY guy around you.
  8. For security reasons I see missing series c.a 5 kΩ resistors with output capacitors.
  9. I have one unit, that is not working, but I opened it and it is obvious that both caps are 220 nF/50 V and they are input caps.

    Kaldas Research

    So quiet ... Does this project live, any new happy owners, new reviews? Maybe some improvements from makers?
  11. In my opinion the direct sun light means direct UV that is degrading many materials. I think that plastic dust cover is not transparent for UV and it means you shouldn't worry about it. But probably more dangerous is heat from sun light. If you do not have windows with infrared filters on the glass (for example I have), it is better to place Stax in the shadow.

    ESTA 4u inside

    Really nice looking stands. At this moment I have Quads ESL63 and I have no more space for another pair of speakers ? But I maybe I will give a try them stacked Do you know that section with highs are on the opposite side when you flip speakers upside-down? For sure the holographic can be better if speakers are in mirror. I have rewired them and the effect is amazing !!!

    Ah, you have one kit for one channel? I see why you didn't do so much with it ... And true, only simple baffle for one driver should be enough + some quick driver, did you consider Accuton? I have speakers with midbass and high from Accuton - for me the great drivers, and really quick for ESL.

    ESTA 4u inside

    Open baffle for computer with small box at the bottom for electronics and maybe some little RIPOL (I have no idea if RIPOL can be made such small). But this is what I'm thinking about. Those Stax speakers are to wide for my bench ?

    ESTA 4u inside

    The open area (I mean the window where stators are open to outside) is 161x92 mm The one stator is 104x171 mm (50x171 mm one part, mind the gap in the middle between stators in one driver).

    ESTA 4u inside

    I don't have any measurements except Stax data on picture. What is the biggest surprise? This is 3 way project ! There are two diaphragms but 8 stators. Looking from the back of the speaker: the left driver is full playing bass and lower mids. The right driver is two way system. The very right part is playing bass and all mids. And the second part is driver with full signal from transformers.

    ESTA 4u inside

    Hello I had a chance to buy two pairs of Stax ESTA 4u speakers. Both pairs look nice, but all four had imbalance issue and I decided to check what is inside and if I can repair them. As you can see, drivers are easy to open. The disintegrated foam's particles got into drivers and stick to the diaphragm (foam was layered with some glue). I had to clean it all from this and use Licron on diaphragms (I did that only with one pair atm). Now the one pair works well, bas is not so strong, but it is enough to work with some active sub. The stereo sweet spot is really thin, but when you seat in the right place the image is sharp and precise. I'm thinking about rebuilding the second pair, but to use drivers to make custom speakers, rather tall, just to use it as computer speakers. Naked driver.
  18. I was testing some KingSound - I didn't like them too, dark, flat, lifeless. Any Stax, even SR-3 are better. What kind of mods did you make to the KingSound??
  19. In my opinion it has a detachable cable, but it's just an opinion ;-)
  20. I wonder what happened? Do we have any others pics and any informations?
  21. It is possible. I have recoated two pairs of old Lambda Signature and they work fine. There is a risk of breaking mylar as I did for the first time, when I was opening driver. But any other try was without issues.
  22. Picture from show in Warsaw (the same where Padam was.): In short, old Orpheus still rocks
  23. JimL - I hope now that you won't call me "heretic" when I publish my amplifier with tubes and chokes I read your thread about using current sources and driving electrostatic headphones. Very interesting, thank you.
