Analysis Plus
I thought this was interesting.
https://www.analysis-plus.com/make-me-prove-it/
NASA recently contacted a number of high end audio cable manufacturers, searching for an ultra high quality flexible cable to allow one of their lasers to be mobile. Our Big Silver Oval and Solo Crystal Oval speaker cable were the only cables which met NASA’s specs for things like rise time and low impedance, under extremely demanding loads. We are very proud to provide NASA with our cables. This is the letter we received after their initial testing.
Hey Mark,
Searching the speaker wire industry for an appropriate transmission line has been difficult with the rarely posted figures.
I appreciate the fast response and shipping. They arrived on Friday, but only yesterday did I get to test the wire types. I unbraided the very ends and attached a stub of flat copper so that I could bolt them on our posts.
Our operating condition was 250us to 1ms 120A current pulses at 80V into our laser diodes. That puts our load impedance below an ohm. I’ve attached a photo of the silver oval prepared. The wires performed very well and are a viable substitute for the stiff flat we currently use. The output of Big Silver Oval looked the best and is most similar to our flat wire. Silver Oval 2 showed a little bit of oscillation at the beginning of each pulse but was well within a stable range. These are the only two speaker cables we have tested that meet our requirements. I like that its nearly as small as our flat also (which is 10mm x 2mm).
No the application is not confidential. The laser’s a high energy, narrow line-width 2um pulse. It can be used for wind profiling, CO2 measurements, and other things. If you need something official though, I’d probably need to talk with others.
I can provide some (attached) but you’ll see in our final assembly that you can’t see the cable itself. We had to wrap it in a neoprene insulator for protection and requirements. We have three sets of these for our system (3 laser pump sources). The cable does work very well for our application. The clamp image is how we translate the oval cable to a high current connector. Our length is about 10 feet.
Will order 100 ft of Big Silver Oval to ship to NASA, LaRC, Building 1202, Room 223, Mail Stop 488, 5 North Dryden Street, Hampton, Virgina 23681.
Hope that helps, Paul

Analysis Plus
I was contacted by NASA last year and since, they’ve bought a number of devices to control vibrations for their testing equipment from me.

Re: Analysis Plus
They tried a bunch from me and ultimately found the Solid Tech Racks of Silence and Feet of silence, Solid Tech discs of silence, etc. worked best for their test equipment.
Of course, being the smart ass I am, I kept asking when they were going to take them to the moon...

Re: Analysis Plus
One of the best sounding systems i heard till today, was Audionet and Usher Audio connected with Analysis silver Oval.
Since i don´t had the money for the Silver Oval, i bought the Analysis Oval 9.
Good cable the Oval 9. I had this cable for about 4 years.

Re: Analysis Plus
What I found interesting was:
Silver Oval 2 showed a little bit of oscillation at the beginning of each pulse but was well within a stable range.
Because about two decades ago, Cyril Bateman noticed that some combinations of reasonable audio amplifiers, reasonable speaker cables and reasonable loudspeakers would ring or even oscillate in the low megahertz range.
Do you know the Radio Frequency Characteristic Impedance of any of the cables? Or just the R, L, C values?

Yes, the Digital Director was used in that setup with MSB monoblocks, and Magico M2's.
