    To anyone who has heard the CRBN, I'm looking for something dead neutral and incredibly fast, detailed, and maybe airy. I don't really care about bass. I'm curious if the CRBN exemplifies these particular traits. My favorite estat so far has been the Jade II on a KGSSHV amp. I'm either upgrading to an Shangri la jr or a crbn in the next few days. Both of them will have a long lead time and are probably non returnable, so I need to choose carefully.

    Avoid Hifiman for chirst sake.

    Spritzer,

    I recall that you were disappointed with the SR-009S bass response in comparison with the SR-007MkII, though you found the bright treble response to not be as objectionable as the SR-009.  Do I have this correct as your main concern?

    Much appreciate your insights on this, thanks!

    The later production 009 (around sz9-4xxx) should be similar to 009s and 009bk in terms of treble. Stax changed something there. Also slightly different earpads, headband, leather headpad(both side made from leather at some point).

  3. Well I don't have a large sample of es1a. I can only speak for myself. The first one arrived with a tilted right driver and a headband with failing paints. The seller was nice and responsive though. He swapped me with a new set. drivers were fine this time, but the headband was still with failing paints. Sent me a sperate headband. Used for a month or so. Didn't fail this time but I doubt how long it's going to last. The paint of the headband doesn't look sturdy at all. I might be biased because of the back and forth. The earpads also mounted in a stupid way. Base plate under the earpads tilted up if you don't use a glue to fix it. In general, build quality of both side earcups are fine to me, but not the headband. It just feels like a cheap DIY unit instead of a well built product.

    The point I want to make here is that it might be a better idea to get a 009 or 007 if you only plan to get one single electrostatic earspeaker. The es1a sounds just fine to me, but the build quality is not up to that level.

    I do think the original Omega design limited them(or him) to design something better built. I personally can't think of a reason why it has to look like an Omega though. If you are making some crap like Hifiman R10 then there might be a reason to steal the fame of sony and bump up the sale. If you can design something sound decent enough just like this one, shouldn't it be a much better idea to just start with a new design instead of borrowing something a few decades old?

    It is a copy of the SR-Omega so it has all the same issues as the Omega... i.e. a headband which Stax should never have used for them.  They break... a lot... and have since 1993. 

    As for the ES-1a, i have been using my set pretty much daily for 18 months now and they are still perfect, no issues at all and always sitting on a Stax stand... even with a couple of tumbles to the floor as I pulled on the cable.

    I just got word that he's cool with me quoting it. He did specify the timeline and it truly was about a year that it took for JR Audio to repair a defective HEV70 from him. Kinda sad and unfortunate that it got to that point. I also recently found out that JR Audio doesn't like to play nice with any of the competition and and doesn't appreciate talks of other diy'ers and other amp builders out on his forums. I think this speaks volume of his character.

     

    From ES Labs owner:

    "I build my own  KGSSHV, and speaking of JR audio, I have a problem with him too. Once I shipped a HEV70 amp to him for repair and it took him around a year. When I receive it the amp does not work. Then I send him a message and ask for help, I am told to do the troubleshooting myself since '' You are an amp builder anyway''. Upon investigation there is a loose solder point on the board. So I do not recommend JR audio product and service based on my own experience and many others who bought faulty amp from him."

     

    In the end, I honestly don't think anybody respectable in the community would recommend JR Audio products, and this quote just reaffirms that.

     

    On an unrelated note, I've been looking far and wide for a new electrostatic headphone and Spritzer mentioned to me that he enjoys the ES1A from ES Labs. This is how I got into contact with him in the first place. Thanks to Spritzer, I think this is going to be my next purchase.

    Es1a is just a sloppy clone of omega. It sounds okay but the build quality is no where near any of the stax, the headband especially. Seems to be 3D printed with some type of nylon coating, which peels off easily like hail.
