Someone explain.

I was reading another thread on here and the subject of mains leads quality came up.  Apparently using a Big Orange Ultra3 Mains Cable IEC Power Lead at a cost of £86 on a TV box or amplifier will improve sound and picture dramatically.
So how does this work?  Surely all copper cables just feed a transformer and the low voltage supply from it is cleaned electronically before used to power electronic components?
So how does this lead work?    The suppliers do not say it does anything, just that it is designed to!
"Big Orange MkII is the latest multistrand mains cable (for greater rejection of RFI interference) that suits most source components and amplifiers. The cable has been designed to improve its performance, the bass is more extended, leading edges more sharply defined and pitch easier to determine."

Almost certainly a standard cable with extra shielding.  whether its worth £80 is up for debate.

Having seen some reviews I can't be sure whether they're serious or being sarcastic.

You have to bi-wire your speakers.

Why not just read that thread? The technical details were pondered already in there.

This works in exactly the same was as someone spending £500 on a shirt or dress (as opposed to £50) feels a huge improvement ...

The more you pay, the more improved you feel.

^This. I'm sure the debate on the subject was well covered in that thread. We really don't want to go over that ground again.

Yes but does anyone want to explain it? Or can they, snake oil salesmen should not reply🥶

"So how does this work?  Surely all copper cables just feed a transformer and the low voltage supply from it is cleaned electronically before used to power electronic components?"

It does not. You are quite correct in what you write above!

Multistrand mains cable . What is that?

There is multistrand wire but that is designed to be more flexible than solid core wire. No improved RF rejection provided.

Then there is multicore cable such as ordinary mains cable Live, Neutral and (usually) Earth

There are lots of other multicore cables.

Interference rejection  is usually provided by screening (as mentioned above ) or twisting of the cores (depending  upon the frequency of Interference to be rejected) . That requires correct termination of the cable cores for the cable purpose to be effective. It is not a 'plug another type and get an improvement'. In some cases  specially designed circuits are required for the caes to be effective. Hardly ever found in domestic equipment's mains circuits. Nearly said never there!

The mentioed cables by the OP do not claim or mention screening or twisted cores and the equipment for intended use are designed for 'normal' IEC connections such as on a TV not 'specials'. Then the power section,  as mentioned OP, does the work for everyone'

If Live and Neutral were twisted ( that is not claimed) there could be some RF reduction potential, if in  an RF environment, AND the supplied equipment was designed to reject, but it pales into insignificance compared with the mains power and voltage in use.

If you want to go for the ultimate, just run everything from battery for a clean power source, mains electricity is by nature "dirty" from all sorts of interference. Don't battle with mains, get your own battery-powered supply either direct to the LV side or use a dedicated high-quality sine wave inverter.

Or just save your money and put up with not getting the last 1% of performance, up to you :-)

Thanks for comments.  The other thread did not explain how these leads improve things just some people saying the improvement was dramatic.
I don't think I will be wasting my money on one.

They can't explain *how* they improve things because they don't improve things.
