Is there an electrostatic Abyss headphone in the future?
Joe needs an ABYSS shirt too. lol....
In a future video I think it would be cool to talk about jps labs. How it came to be? How long it's been around? What does the future holds for new cables etc? Obviously jps labs is know for cables but they have made other interesting stuff such as bass alignment filters for b &w in the 90s . Thank you for all the videos guys! Perhaps a tour of each of your work and/or home systems in the future. Cool to see everybody's toys they enjoy!
Yeah that would be a cool video to watch
I just bought a Blue Hawaii electrostatic amp, very similar to the famous BHSE from HeadAmp but a different build from a different builder. Anyway, it really brought my estats to life.
Most of the electrostatics just use a conventional amplifier with a step transformer on the output. Those boxes the stats and electrets plug into are just transformers and a dc bias supply. There are some direct drive amps but those are typically very expensive. The only difference between electrets and electrostatics is whether the charge on the diaphragm is externally driven, or incorporated into the diaphragm 'permanently' in which case the diaphragm is called an electret. Think of it as analogous to a permanent magnet, but with charge, and yes, the charge does dissipate over time, absolutely no question about it, and it is NOT subtle. My Audio Teknica TK33 electrets have gotten very puny over time, the sensitivity is way down, and the bass gets all rolled off to pretty much non existence, and they were flat to 10 hz when new. I've thought about 'recharging' them, and the process is pretty simple, but requires some good fairly accurate temperature control. Oh, and the transformers are not cheap because they have to be built to be used in an audio amplification chain with any hope of being at least not totally 'opaque'. At best they are severely non linear devices. I just picked up some Stax SR5s and they should be here tomorrow, an early Christmas. :-)
Talks about type of dac would be fun too I guess. I'm very new to audio and I come across terms like r2r, multibit and some other similar words when reviewers discuss dacs.
We covered DAC’s in at least one past video, ruclips.net/video/lqCf8M1LQCQ/видео.html
@@ABYSSHeadphones thank you. ☺
Yeah a Dac deep dive might be helpful.... I've been looking at Holo Audio product lineup and they have 3 models (Cyan, Spring, May). Each model has 3 levels 1, 2, 3 aka KTE ( Kitsune Tuned Edition). Reading reviews and reading the technicals on each model and level is enough to make your head spin. Especially as they have solutions from 1 - 5k. They are all R2R ladder Dacs that specialize in Non Oversampling modes.
It Is possibile use a stereo amp (like the AHB2) with an electrostatic headphone?
audiovalve solaris can do all of them.
Well AudioValve manage to design amps for both conventional headphones, electrastactic headphons as well as loud speakers.
RIP
I want Eric`s shirt soooo much.

Would I be correct in thinking that an electrostatic energizer is simply a normal amplifier with a transformer between the outputs and the driver? I can't seem to find any vids about the circuit topology. Cheers guys, mega love xx
That is the simplest concept, but only half of it. A normal driver is two wires, electrostatic drivers need 3 wires. 2 for the audio + and - polarity that has been amplified to have a higher voltage. The extra/third wire is attached to the thin diaphragm. This requires a high voltage, low amperage charge. This can be a positive charge or a negative charge, doesn't matter so long as it is one or the other. This acts as the magnet in a normal driver because it gives it a constant polarity. This also determines which way the diaphragm will move (the phase of the driver), so they make sure they are correct or it'll be out of phase lol.
