And was made years ago when John first brought this up. But he keeps regurgitating it.
Actually, Ohno developed his heated mold process for the continuous casting of fine wire and thin foils. But the companies that are making it (and marketing it pretty much exclusively to the "audiophile" community) cast rod and then draw it into wire.

Oh No
Good to know, all of the current sources of Ohno CC seem to be drawn...
Also, to those interested in the Beveridge ES line source speakers, note I made a spelling error originally, the correct spelling is Beveridge, and Harold Beveridge's son Rick is now owner and seemingly still in business in some fashion (index), although it is hard to get information.

Not really, IC thin film resistors are VERY thin and the performance is there, no excess noise, sub-ppm linearity (the thin film "target" is very secret sauce).
IBM has a 15 metal interconnect layer process with some layers so thin IIRC resistance can be >.1 Ohm/square.
Thin Film performance
That is as I suspected by my own experience with thin films, I was just trying to get you to add your own experience to the dialog, Scott...my apologies. I'll just ask next time.
And it's true about secret target alloys. For several years we ran a "gold" target to metalize CDs which we offered at greatly reduced prices relative to what we charged for actual gold metalize. I had a couple of other replicators ask what it was and told them it was "gold looking" which pissed them off. I had noticed the new Euro coins looked like a nice light gold color which resisted oxidizing pretty well, so I paid my target manufacturer to purchase a large round of the Euro-gold alloy (90%Cu+5%Al+5%Zn) and make me some targets with it. It gave us a nice advantage for a while... My techs were happy as well, they hated having armed guards and cameras around every time they ran or serviced a metalizer with an $80,000 chunk of gold in it. They were sure they were going to be knocked off by some idiot stealing metalizer shield debris...

Yes there are some similarities, but Merhaut's patent was issued earlier
Patent US3590169 - Electrostatic horn loudspeaker - Google Patents
I really heard that similar principle speaker was produced in UK.
Regards,
Not sure but probably not 9-9's pure in either case. Could even be both.
BTW we had a problem for a while with platinum thermocouple wire going AWOL, seems they shipped and received it like any other wire.
What you came to find you don't understand and keep trying to pass it off as something meaningful when you've shown no such thing. You just keep regurgitating like some politician's talking points.

And you do that under the delusion that our subjective perceptions are some unerring reflection of the objective reality around us. Which is why you'll never make any meaningful contribution outside the stagnant backwaters of "high-end" audio.
Seriously, you're like the child who puts a tooth under his pillow at night, finds a quarter there the following morning, and concludes there must be a Tooth Fairy. I mean hey, his "colleagues" all found quarters under their pillows too when they did it.

They used to be next door to where I worked. My memories of the speakers are fond. I saw a pair there for repairs which had actually burst into flame during a loud passage.
The progression is, experiencing how impressive music reproduction can be when everything is in alignment, how it makes the normal standard, accepted by most, as being quite pathetic in comparison. Hopefully, this can be repeated several times to drive the message well and truly home.
Then, a decision is made as to whether that above ordinary replay was due to a 'magic' ingredient - e.g. a hideously expensive, energy gulping amplifier, or a completely OTT speaker - and therefore cannot be repeated unless that blessed component is part of the mix - or, as in my case, that this is actually nothing more than a fortuitous combination of audio elements, sufficient to get one over the hurdles that normally prevent audio reproduction subjectively sounding that good. If one takes the latter option, then the audio world opens up - you know the experience can be repeated at any time, merely by making enough effort to engineer a competent system ...

This about sums it up, every comment on them over the last 30+ yrs has been about the same, including those from Mr Audio Critic, where i first read about them many moons ago ...

You'll get a lot more out that 60min. than here.
Dan Sheingold who is still here at 80+ knew George and wrote their in house mag. "The Lightning Empiricist". There was a profile in one of the later issues, he was somewhat a renaissance man, poet, artist, many interests.
