    How long did you burn them in? 😂 /joking

    current feedback electrostatic amp

    No problem, Jose. Just having a very bad day on my end, and seems like I took it wrong.

    I’m drinking a beer ATM. So witch is your favorite KG all Solid State Amp?😊

    current feedback electrostatic amp

    I only listened between the CFA and GG with my SR-009. I like the sound of the GG quite a bit better. Can’t say where everything sits on an absolute scale. So I am fair, but not as experienced as others here. That’s all.

    current feedback electrostatic amp

    That answers a lot for me. I have a breadboarded CFEA up and running and was not warming up to the sound of it. I set it aside and went back to my GG, much prefering it as my daily amp. Maybe I need to play the CFEA for hours as you suggest to really retrain my ears.

    Maybe a cold solder joint on the PCB between the terminal block and the base pin of the input JFET? Try reflowing the connections on the -I side that distorts.

    The ultimate DIY? A Stax SRM-T2!

    What tubes? JJ 6CA7 and KT77 tubes have problems in the DIY T2 circuit.
  8. What $24,000 will buy you these days. PS: it’s parent company is Sonoma Acoustics. https://audiophilestyle.com/ca/audio-shows/exclusive-warwick-acoustics-aperio-electrostatic-headphone-system-r792/ https://cdn.computeraudiophile.com/article-images/2019/0416/The-APERIO-from-Warwick-Acoustics.pdf Must not sound too good, as the video is silent.

    FYI: Search on eBay for STAX EP-007. Five Japanese vendors have pairs for sale there.

    Something lost in the translation to Chinglish? 😲 I learned that Fang is either a retard or deliberately trying to con his customers by using an Ohmmeter to “measure” the DC resistance of a transformer with 1000VDC across it. All in an apparent attempt to negate/quantify transformer AC leakage impedance/reactance current that shocked the YouTube video guy. Naturally, the VOM’s overvoltage protection kicks in and an “infinite resistance” is displayed. Just as intended? You don’t need to be Penn and Teller to spot that slight of hand.

    Very interesting the design innovation and manufacturing development you are sharing here, Aumkar. It’s a pleasure to see such openness and transparency in this over hyped headphone market. Looking forward to hearing them when available.

    For part time use for a hobbyist, those look perfect. When cutting or hacksawing screws to length, always first screw a hexnut past the length to be cut off and then mark the cut line on a single wrap of masking tape around the screw. The tape helps the hacksaw from walking, and after the extra length cut off, unscrewing the hexnut helps straighten the mangled threads. Cleanup with a chamfer on the end using a hand file.

    I actually tried to get banned over there Pars. Even called John Amatto a Gaslighting Audio Whore. They just deleted both of our back and forth posts with a warning. 😂
