You will need to get all the old electrons out of the cable first. Else the digital circuit will revers its zeros and ones.

Someone may say you need burn in to hear differences. Even gene from audioholics would disagree unless proves to him on AP with evidence. He even test one of the most expensive cable money can buy and test result is virtually no difference from cheap cable. It does gives you great aesthetic.

We could really do with one of those 'banging your head against a brick wall' smileys.
Yep, just closed my eyes, sat back and listened.
Sure he must be trolling... He's even afraid to specify which cord he bought
Again: if something as simple like a passive power cord makes a difference in your setup, you have some serious problems with your electricity.
Maybe @WiiM Team themselves could tell us once and for all if there's any technical benefit to changing the power cord.

I think that WiiM would wisely not step into a cable war, particularly one around power leads…
Fair! Probably not worth the hassle
All I'm gonna say is that I completely disagree.

Perhaps he doesn't know the make, probably borrowed it from his electric kettle...
I definitely don’t agree. You’re just having delusion. Does the water flowing your garden hose taste better in rubber over metal?
Cable is one of snake oil out there.
Human hearing isn't sensitive enough to notice any difference. Save your money.
I have a bit of sympathy for those who hear differences that others suggest probably don't exist. Some years ago I read a book by Dr. Cordelia Fine called "A Mind of Its Own - How Your Brain Distorts and Deceives" -- it was a detailed study of just how complicated our brain is and how easily influenced by various factors. One example was a study that found experienced soccer referees consistently judged a tackle more harshly if the offending player was wearing a red jersey instead of a different color. Dozens of other examples were given.
Besides "expectation bias" where, in the case of audio, we hear what we want to hear, there is also the issue of subconscious bias -- like the red jersey. We would think many issues wouldn't have any influence on what we hear, but they do. Note that if we were aware of the influence, it wouldn't be "subconscious"!
The catch is even when double blind tests show we aren't really hearing what we thought we were, we don't do our everyday listening in a blind setup. We know what equipment is involved, and in most cases, can probably easily see most of the gear from our listening position. So it is not surprising that a particular brand name, or perceived technical details, the gear's appearance, and so on may influence what we are hearing. Throw on top of that the listener's physical and mental state at any given point and there are a lot more factors to consider than just sound waves.
As I've often noted over the years, I'm the biggest variable in my system.
So, to wrap it up, while I'm not a cable guy, I can certainly see why some people are. If it works for them, is in their budget without depriving others in their family of what they need, and increases the pleasure of their listening experience, then have at it!

Sometimes it is so easy to find the right scientific explanation.You will need to get all the old electrons out of the cable first. Else the digital circuit will revers its zeros and ones.
And remember that electrons inside a cable are really, really sloooooooooooow. In a copper cable of 1 mm² at 1 A of current they move just approx. 0.074 mm/s. Consequently, it takes almost 8 hours to get all new, fresh and unbiased electrons into a 2 m power cable!
And that's just the mean value! Some of the lazy old electrons spoiled by prior use will hide and not move all that willingly. Some will seek shelter close to a nucleus, setting free other old and used electrons. To make up for this effects it's not unreasonable to ask for rinsing the power cable 20 times the average during burn-in.
Following these calculations we end up at ~150 hours of burn-in, which correlates very well to what experienced listener's with highly resolving systems and cables found: one week.
And just to make sure nobody falls for this: Unfortunately it won't work with AC at all, not even in theory.

A quick addendum to the above -- sure, have at it, but just don't expect everyone else to buy what's inside your head....

Another quick addendum…He never said everyone had to agree with his opinion.
