Today the first public demo of the SR-X9000 are held in Tokyo, there are various opinion floating in japanese Twitter.
Let me try to translate a few review.(editing google translate result since I am too tried after work to write everything from starch)

The SR-X9000 has a "lush sound", giving the impression that it is softer overall and has a much wider soundstage than previous products. The tuning of the sound so far remains the same compare to the 009/009S, but still the difference is noticeable, where the SR-009S feels much dry and simple . SR-009 and SR-009S are natural with a delicate expression with thick and high resolution, while appealing the sound itself directly to the ear and producing a sharp sound with lines. However, with the SR-X9000, the thickness of the sound is more soft and lush, but the contents are dense since resolution are much higher, taking electrostatic soundstage to another level, adding musical expression and the three-dimensional of the overall sound. I felt like I can feel it leaves reverberation.
What I felt with the SR-X9000 is that, for example, the violin's crisp high-pitched sound is expressed with a margin. SR-009S and SR-009 tend to appeal directly to the limit value of high-pitched sound with the thickness of the sound, but SR-X9000 gives more space than the limit (reverberation) and is lush.
In terms of sound volume, the instruments that are ringing behind the vocals have a clearer sense of separation than the SR-009S and SR-009, and are naturally expressed in places away from the vocals.
In SR-009 and SR-009S, these incidental sounds seem to be almost on the same line as the vocals due to the influence of the thickness of the sound itself, but this time the thickness has been relaxed to reduce the volume of the entire sound. Recognize that you can feel more.
Other opinion on twitter includes:
- The STAX SR-X9000 has a good acoustic texture, but the soundstage is not as good as palnars when using a high-end amplifier. Well the amp is too rubbish.
- The Sr-X9000 retain good neaturallity and higher resolution in sophisticated sound
- I tried listening to STAX SR-X9000 (driver is T8000). The difference from 009S is
・ Not as Heavy
・ Music genre is almighty
