    It was a small batch made customized. The factory did everything for me. ps. I have some spare.

    current feedback electrostatic amp

    Done. I miscalculated the height needed for all the stuff on the amp boards, so the build is super tight. As the first one made as a prototype, I think it's good enough. I will increase the width and depth by a little bit next time. Now for some serious listening and comparison with Carbon and GG.

    KG Balanced Dynahi build discussion thread

    Made some multi-coated front panel recently. This is a small project @ang728 and I ran together. This is our first attempt to try multi-coated for the front panels. I don't know if this kind of finishing will start to peel off in longterm. We'll see. We are thinking making more interesting colors, too. Maybe "Hulk" green or something like that... The blue one has tapered feet while the red one has real spiked feet.
  8. 4 grhv, 2 grlv78xx, 2 grlv79xx, 2 main board, 2 mini t2 please

    some questions about electrostataic amp

    use modern SMD ones like STN9360 instead of 2sa1968 on taobao.

    KGSSHV Carbon Build Thread

    RK27 are sometimes prone to imbalance at low level. Despite this, the overall performance is good, especially considering the price. Stax uses RK27(customized), too.

    Blue Hawaii BJT Build thread

    Not really. I think GG has better vocal while Carbon has better both ends extension and a little bit wider soundstage. BH sits between them.

    Blue Hawaii BJT Build thread

    It's finally done. Negative GRHV output resistor changed to 3.3R. 170D was substituted with ROHM in GRHV. As for sound. In Brief, the BH sits between Carbon and GG.

    stax t8000 clone (well sorta)

    How does the sound compare to T2?

    The Multi Amp aka Dynalo Mk2

    Except from K170 and J74, what else could be used as front end? K170 and J74 are long obsoleted and prices are high now. Any easier sourcing / cheaper substitution? I know linear system has some but the prices are high too....
