Too true!
Powering WiiM Pro Plus with a power bank

Of course I agree in the term, when it makes you feel good and you believe it has a positive hearing experience for you - go for it! No matter if it is placebo!Interesting theory.
'The only thing..'
How can you prove you are not fooling yourself?
Bud, it doesn't really matter if it's real or not. If you like it, you like it. No one can experience what you experience. No one can deny your experience.
You'll have to get used to uncertainty. Uncertainly drives discovery. Discovery means change. I can see why folks are afraid of change. They like rules.
Some might really need to reconsider if music is a suitable hobby for them given that's its a phycoacoustic experience.
Instead of a power bank that has a internal battery management circuit, I'd rather use a combination of;
I'm not sure whether this can improve sound or not, but it is unlikely to introduce any power-related noises.
- battery cases - each holding 4 D battery. Two battery cases are wired together in parallel for higher capacity and/or battery change without shutting off. This will power WiiM with either 4 or 8 batteries.
- metal hydride rechargeable batteries - D-size, 1.2V output. 4 D batteries in series output 4.8V
- USB-C power pigtail - 2 wires to connect to battery case

I replaced the included (WiiM Pro) 5V USB supply with an Apple 12W supply that I don't use for anything else anymore but that was just out of safety concerns. It's better build, stringent safety certifications, lower leakage current & very stable at high(er) power draw. Did the same with my Topping DX3 Pro+, it now has a top quality Mean Well 15V power supply.

If you don't have all the equipment to measure differences in your testing but your ears, you can always have a couple of friends come over and let them act as the blind test portion.
When their mouths drop, then you know you were (confidently) correct all along. My friend has a lot of testing equipment on his bench but we don't need it to know about changes/improvements. The bench tests confirm the details.
.Think the issue comes where only some limited measurements are claimed to determine audio equipment performance.That's what some believe and others argue against from a scientific point of view.
The human ear has a great depth of perception and beyond today's audio measurements. This is the case today and going back decades.
As one famous designer of an American audio company today has said, "Measures great, sounds like shite."
True story.

I'm not going to challenge your believe but the above statement is false.

Leave them be. They‘re in another camp. You can have your fun with them but not argue. Useless.
You can challenge my experience and ears if you like. Actually, if you look back over the decades, there was measurements that were highly presented as most significant that did not turn out to be the end all. I've had amps I fancied back in the day like a Yamaha integrated, it was tops among an AX series.
Had kept it as a backup in the late 90s when I obtained some midrange Rotel 200 watt amplifier and preamp to drive B&W speakers.
When a minor issue came up with the amp, I put back in the Yamaha AX700u, glad I had the backup.
It sounded hard, sterile and frankly awful compared to the midfi Rotel amp and preamp. But hey, the Yamaha measured great!
Ok, we're getting off track so I'll point out that my experience using a battery driven WiiM Pro in my big tube amp monoblock system is superb and leave it at that. Enjoy the music and a blessed Happy Thanksgiving to all.
Kinda think of myself as being in both camps. Today, we have equipment that is available to measure but in the end our ears play the final decision for any number of reasons from the room to the sonic benefits in separation, tonal character, spatial perception, etc. I've seen results from both and doubt the journey with the human ear is concluded, IMHO. We will learn more.
Not a very good example, as Amp components deteriorate over time, as you know…

The hi-fi press always used to criticise most Japanese amplifiers didn't they? Maybe they didn't have enough distortion
I didn't say you should measure stuff instead of listening.
I do say that you cannot trust your own listening experience, no matter how many like-minded friends you bring along, unless the listening environment is well controlled and statistical methods are employed for evaluation.
You cannot escape the multiple biases we are prone to, even if you know about them.

The example is apt. While the midfi Rotel equipment was new, the Yamaha integrated was hardly old. It had maybe five years.
But hey, the
No one breathed a word about this current American audio manufacturer. I know he can be trusted and so can my experience and ears.I didn't say you should measure stuff instead of listening.

Also, I use dual Cisco Meraki switches from a fiber optic router going into a WiiM Pro. Very impressed how standard Blue Jeans Ethernet cable’s with the Meraki do so well in my quality system. (I removed the Meraki power supplies but dream of further mods.” Ok, repeating the great American audio manufacturer. Do you think you know better than him? In the words of Penelope Cruz, “I dun think so.”

I thought you were going to say Paul McGowan
At least I tried to directly address the part of your posting that I replied to. You don't seem to care as long as you can repeat what you said before.No one breathed a word about this current American audio manufacturer. I know he can be trusted and so can my experience and ears.

That's not a sensible way to discuss topics.
If you are more interested in quoting the chosen ones, keeping their secret knowledge, you're free to do so, of course. Just be prepared that I might continue to point out how pointless this is.
