8000 feet of custom cable is a very small order. 3000 feet is what I would get as a sample. Setting up to make a custom cable is pretty involved. If its just bundling different wires in a jacket its still the process of getting them twisted together so they can be jacketed. If you start from copper drawing stock there are many more steps involved.
Some of the machines used for high volume cables like network cables are well over 100' long. And it takes some running just to get it stable with consistent jacket thicknesses.
The classic problem with project management is that you don't know its late until its actually late. You can put your own guy on the floor of your supplier and still the house of cards collapses when the paint, sheet metal, screws, etc. trivial item is out of stock when you can't afford it. It's also why going from nothing to 4200 cars a week at the Tesla factory is a monumental task.

I have hesitated to contact you mostly over the digital part. Care to elaborate, digital what? IC's from datasheets with a few parts? Complex EQ's, new DAC?
Demian,
It is a sample run, but there are folks who will even do 1,000' custom. The cable in large quantities drops to under $3.00 per foot. It is all standard copper with a not as common, but stock insulation, jacket has a few bits and it is one of the machines involved in wrapping it that broke.
The last time I designed a custom stadium cable it became a standard item. One of next weeks projects is to visit a high school football field and show them it actually is the loudspeaker cable that is causing the far loudspeakers to rolloff at 3,500 hertz.
BTY there are two cable manufacturers I have used where a chat with the chief engineer brought up new issues for both of us.
yes, I understand the effect 15nH might have on a high freq circuit and would use that bulk value. My thought was not a practical one....sort of falls into the area like the L of a straight wire (not looped back) No 'real' application for it.
I didn't have any solid #22 awg. It was floating in free space away from floor or other objects.

Wavebourn, you missed an opportunity. I could have introduced you to Jack Bybee who was right there, IF I realized who you were. As I said, I confused you with another Russian who I first helped back about 30 years ago and who had been working at Plantronics (sp) in Santa Cruz for years. That is why I asked you where you were working. When you said 'at home' I thought you (who I thought was the other Russian guy that I know around here) had lost your job. I felt guilty asking. However Jack was right in front of you and we could have had a conversation. Perhaps you would have learned something new.
I am the primary circuit designer of the new Audible Illusions Phono preamp. Art does the rest.
A lot of folks in the commercial world. Some of the systems even get up to 8,000 hertz with equalization.
I just looked at bybeetech.com. The home page has a big banner "Slipstream Quantum Purification" - sort of tells you all you need to know.
Thank you for the understanding.... large complex scientific projects are a mind bender.... and why they only developed people from within for such work. But in the end, I had to leave because of burnout and also, I needed to make more money for my retirement years.
No. Not really. Spending a lot of time indoors trying to stay cool.
Whats up?

Thanks.
Why should I bother?
Voltages and currents at least show something usable. What's the point in measuring average temperature over the clinic, for example? Patients either have a fever, or are dead. ;-)
Lift it up from the floor 😀
Seriously, I never said that it was my system. It was my amp. 🙂
Sure, clipping is barely audible! It is what I was targeting for: soft clipping like triode without feedback, low intermods close to max power like in PP with significant feedback, zero distortions on low levels like in SE, and high output power like from penthodes when they are not strapped in a dumb triode mode.
Yes, I hope to get some orders. If people pay for much worse amps and praise them in reviews, why not this one?
Thank you Dan.
Do you mean that with my cheap JBL 990 monitors you liked it more than with $12,000 speakers?
Thank you John. I told you that I am Wavebourn. Yes, I need somebody for legal advises. Except Wavebourn that is a sole proprietorship, I have a startup called Bogorodsky Power Corporation.
