  1. Really nice job. I would love to have such skills How do you measure headphones?
  2. I had X9k over the week at home - my wife and kids decided it is not better than 009 and 007 mk1. The lack of impact and energy in bass region was the problem for them, not imaging. Personaly I liked them, but didn't feel like this is my cup of tea. In my opinion they are very different to 009, are little closer to my Omega with 007Mk1 drivers. Would be nice to have them in collection and try them with different amplifiers, but after all I abandoned that idea.
  3. For example what CRBN's does better? I have no chance to even look at one pair of CRBN, but I want to be well prepared when it happen
  4. That is really sad true - they are doing little progress or even backward lately but prices always go significant higher
  5. Your link to the image doesn't work 😞 Can you just paste it here, please?
  6. 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 .....
  7. Could you share more pics and a little bigger (that last is terrible small) ?
  8. Thanks a lot for your efforts Todd !!!
  9. 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?
  10. 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.
  11. For security reasons I see missing series c.a 5 kΩ resistors with output capacitors.
  12. 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.

    So quiet ... Does this project live, any new happy owners, new reviews? Maybe some improvements from makers?
  14. 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 !!!
