Powering WiiM Pro Plus with a power bank

"When people don't understand, they invent their own explanation"

Too true!

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.

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!

Instead of a power bank that has a internal battery management circuit, I'd rather use a combination of;

• 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

These are off-the-shelf items and relatively easy to rig up.

I'm not sure whether this can improve sound or not, but it is unlikely to introduce any power-related noises.

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.

That's what some believe and others argue against from a scientific point of view.

I shall try it on my coffee machine.
My girl friend will surely smell the difference from another room.

Think the issue comes where only some limited measurements are claimed to determine audio equipment performance.
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.
