Yea you measure the cord and il measure the incoming Butthurt it's bound to inspire.
What could possibly go wrong.

Test them... for what?

As J Kenny already mentioned, guessing is guessing, measurements is measuring...
Oh my ... I have been infected.

...Did you measure the 50Hz pick-up from your TT already? If not, don´t do it, otherwise the infection will go worse!

Hard to do as my TT's are all in the attick.
Last time I looked it was an inferior and ancient method for reproducing music.
I just took some anti-idiotics to get rid of my infestation.
But in the past sometimes I was bothered by audible hum... always turned out to be a grounding issue.
On a more serious note, for screening to properly work the screen should be connected to the ground pin and the groundpin in the power inlet of said device must be connected as short as possible to the chassis of the device.
I would recommend twisted mains wiring and screened only in very specific cases where one cannot use properly screened and high source impedance low voltage sources.
Otherwise me thinks a decent power cord is sufficient.

Whether they can be used to punish your forum moderator....
Alternatively, their current carrying ability.

Go for "shielded" ones, that helps...
Most Hifi equipment is designed to be mains powered.
If anybody working for me had designed -anything- which didn't work properly unless used with some sort of special mains lead or signal conditioner They would have been looking for another job.
I don't believe it could, myself, but any piece of hifi which benefits from a special power lead has been incompetently designed and I would recommend avoiding all products from that particular manufacturer.
Mains poweret kit needing special mains cables - ffs!

Very nice...but didn´t you post beforehand...
"Not needed. Full stop. Period. "
...could it be that the infection still spreads down-under?

I meant with music signals.

Such pretty cables!
Still too expensive but I guess you have to pay for pretty. Might as well buy Pangea cables at those prices: https://www.audioadvisor.com/prodinfo.asp?number=PGAC14
I spent $101.64 to replace all 12 power cords in my home theater and stereo with 14AWG TrippLites. Hoping to make between $500-$600 selling my Pangea cables.

...you leave no choice to me
,one from a bunch of shielded ones (this one extra short for a converter´s DC power supply),
home made, around 10€, depending on the min. length of industrial shielded cable you get a hold of, this one has
2x 1.5mm² plus shield as ground line:

Any reason why you didn’t use a 3 core cable? Quote often the screen is not rated to withstand potential fault currents.

It would also depend on whether the screen would be steel or copper.
Good catch, when it concerns safety earth (and is what it indeed is for)
Best would indeed be to use a 3-wire cable and the screen connected directly to the chassis.
Alas mains plugs only have 3 connections so the screen would have to be connected to safety earth (PE).
