So a new electrostatic seems to be incoming: https://apos.audio/products/sjy-argos-electrostatic-headphones?utm_campaign=hyperfuse_last_day%20%2801KZW4554JVNW58G1HET4TN43W%29&utm_medium=email&utm_source=alex_nongdpr_never_subbed_active_180&_kx=cd77Rbf3yu6_OAujM-M4VU1ihuQFsjtyVcb-jl8r-OKxvi62Czezy2yxdLQUUnAj.Ldk8SW I've been keeping an eye on them for a while, no idea what that company is but hey, more the merrier and all that. I just saw the new updated page for these and it is just what the fuck, are they retarded? First off, "fully vented drivers" being spun as something that is positive. Hello, what is the number one rule of planar design? Something about an infinite baffle? No? Anybody here have any fucking clue what they are doing? No? Let's spin our engineering ineptitude as a positive Yes, that is what the drivers need, room to breathe. A common problem with all planar drivers is that they are just being suffocated. What a novel idea and people making planars for 70+ years have clearly all been wrong. Seriously, who thinks the actual reason is that the drivers are horribly unstable so the extra pressure from a sealed baffle would knock them out of balance. So instead of fixing that, let's just employ marketing wank. Then we have the cable... what the actual fuck. Just look at this thing: Anybody who makes a braided cable for electrostatics needs to be taken out back and beaten repeatedly with a copy of the Art of Electronics. The whole point of the fucking cable is to minimize capacitance... not add to it!! Now this looks like the cheap crappy headphone cables coming out of China so I very much doubt it's high voltage credentials. I also love the Y split on a commercial set of headphones... a piece of clear heatshrink. It's also 1.5meters in length, probably to cut down on the pile of extra capacitance this turd adds to the load. Then you can get a proper extension cable and have the headphones reach anything as these are hardly portable.

you mean this grossly overpriced piece of antique design. unbalanced and lots of feedback. clone boards were available somewhere at diy audio. chassis filled with many audiofool components. like bybee's and fancy caps. if 50 watts into 8 ohms is what you really want then build my pioneer a09 clone. lots better in many ways. i could publish pictures of the zahl boards, or the mass kobo. both of which are also grossly overpriced pieces of garbage.

For what it's worth, my CFA3 bords fell 2,5V short in terms of offset when I built them. In my case, swapping all the red LEDs to a version with much less forward current than the ones I installed first (I'm now using LTL-4221, which has 2mA I believe) put all numbers back in the right places.
