    Where did that number come from?

    STAX announced new closed sealing covers and ear clips (eliminating the wire headband) for retro fitting existing SR-001mk2, SR-002 and SR-003/003mk2 IEMs. Supposedly the CES-A1 combo will be available in Japan mid-December. https://stax-international.com/products/ces-a1/

    What’s your opinion on the sound quality of these Shure in-ear electrostats vs the STAX SR-002/SR-003mk2? The Shure have to be less painful to wear.

    KGSSHV Carbon Build Thread

    You might consider contacting @joehpj . He has developed a two case solution for both KGHV Carbon and Grounded Grid amps. If he still has the bare cases available, it makes for a clean looking finished amp at a very attractive price. My GG in the photo. Carbon looks similar without tubes protruding.

    Thanks. I’ll give Digikey my order. Looks like I’ll have all the parts to try the little amp out. I’ll repurpose the PS from my KGST to power it. Thanks for the resistor confirmation. The BO slide on that BJT is not too encouraging...

    Bought these PCBs from the GB awhile back. Looking to order the in-stock resistors to start. Are the values shown currently good to use? The schematic done earlier is a little different. Thanks.

    Have you tried isolating the problem by wearing your headphones backward to see if the channel imbalance flips ears (stays with the R channel earpod)? When mine seem imbalanced, turns out a good ear cleaning does wonders.

    I’m pretty sure Birgir has plenty of dough.😁
