You ever get that $500?

@Speedskater Thanks for pointing out Jim Brown's work. His website has a lot of very good information on the subject of RFI. http://audiosystemsgroup.com/publish.htmThe speaker cables can be interference receivers from other applications. Jim Brown EMI/RFI expert sometimes warns about this problem.
The first seven pages of this Jim Brown paper, explain a lot of things about interference. The remainder of the paper is about ferrite chokes.On page 65, Jim did say always use twisted pair cables for loudspeakers. He didn't give a detailed explanation on exactly how RFI picked up by speaker cables would lead to problems.
is this a poor choice for internal wiring between a DAC and amp? its what I have on hand https://www.amazon.com/Shaxon-SO18-100BK-Solid-Copper-100-Feet/dp/B00IN83AC6/ref=sr_1_2?keywords=shaxon+copper+wire&qid=1566564194&s=gateway&sr=8-2&th=1
connecting a jds atom to a khadas toneboard, inside the atoms enclosure.
That depends on what else is inside that enclosure. Once upon a time, I had a computer that was so electrically noisy that parallel ATA drives wouldn't work at the higher speeds, not even when using a cable with extra shielding. SATA was just becoming a thing, so I got a controller and adapters for the drives. The differential signalling had no problem working at full speed.Inside an enclosure any normal electrical wire will do just fine.

Or a switching power supply or power amp, which is what I was wondering about when the question was first asked.
My point was that high speed digital circuits need proper differential connections. Audio doesn't at reasonable distances (but they do help avoid ground loops).
I think we're all on the same page, just looking at it from different angles.
Hmmm... IME twisting wires does provide some shielding effect, frequency range and such depends on the twist ratio. When we're routinely looking at -100 dB kind of numbers even a short distance can lead to coupling that degrades SINAD. Whether it matters is very much dependent upon the application and environment.
