Sorry if this had been covered in here, just became aware of this from the current fraud thread.
I realize what the DTCD Shunyata Test shows as a “difference” is meaningless, and a smart engineer or physicist, left to his or her own devices (see what I did there) could probably come up with an input that would measure differently in output between their product and a standard, but I am surprised they came up with anything that showed a difference capable of being measured (if it really did, the graphs are printouts from excel spreadsheets). So, has anyone figured out what their proprietary test is measuring? How they do it? I figure they have come up with something akin to white noise, or pink noise, or even “garbage in” which works “better” or faster for their cable than a std. black cable. Is their testing capable of being reversed engineered to show for example how they get different curves on 3 std cables with different gauges?
I’m surprised there is any measurable difference at all for speed, current, etc. But here’s my expertise on this. My Father was an engineer at Ampex, associated with instrumentation (telemetry) on things like Navy and Air Force ICBMs, rocket and moon launches and recording that data, and playing it back and converting it to a useful format, with some pro audio recording and duplication mixed in. We built some amplifiers and other things together when I was a kid. When I wanted to use a heavy duty AC cord like on one of their commercial pieces of equipment, he would say, “not necessary, won’t make a difference.” My response, being 8 or so, “why not” or “how come.” He would say, pull out the fuse we put in that circuit, and look at that wire that runs on the inside, all of the current has to run through that tiny wire, putting car battery cables to an AC plug, or anything else than what code requires is going to make a dimes worth of difference.”
So since 1968, any piece of equipment with a fuse doesn’t need anything more than zip cord in my mind and that’s the furthest I will ever go with it.
