Humans have brains that can be used to learn things and to reason about them. It's what seems to set us (some of us) apart from the rest of the animal kingdom. If I say that my stereo sounded better after I hit my thumb with a hammer, would you believe it? Would you try it? Probably not. So it's a matter of degree. Some people have a lower threshold for belief than others. The differences between people are a mystery. Sometimes it's education, sometimes it's ignorance, sometimes it's insecurity, sometimes it's security, sometimes it's wanting to fit in, sometimes it's wanting to feel superior. Whatever it is, people tend to be resistant to change their beliefs, whatever they are based on, even if reason tells them they are wrong. A lot of people think that because they know the ears/brain are easily fooled by various techniques, they can't be fooled. A lot of marketing effort (and scams) is aimed at such people.
I've always been amazed at audiophiles who listen to CDs and high resolution streaming services, and speakers, etc., demonstrating their belief in engineering, who think that while the engineers can design all that stuff, they just can't seem to get the darned cables (or power supplies, or network routers, or whatever) right. And some hobbyist without any technical training or test equipment can stumble onto the one thing, the one combination of materials, the one braiding pattern, the species of wood, that will suddenly make all those engineers' work worthwhile. As a former EE, I find it both a little insulting and amusing.
Carry on...

Where did I say no one can reply to my posts? Have the right to specifically address anyone I wish and to specifically note same, no matter how you don't like it.
It appears to be an audio industry trend. Manufacturers are designing to allow for this area of improvement. You see more and more audio products coming out with LPS internally built-in. That Manely Labs notes the positive impact with a new power supply design, the potential for possible benefits across different audio gear grows.
Personally, I'm interested in trying it with my tube amps. Where do I put that tricky car battery proposition?

No, it's just a trend amongst trolls.

Interesting article
New Study Reveals Why Most Audiophiles Still Fall for Snake Oil Without Realizing It | Headphonesty https://www.headphonesty.com/2025/12/study-reveals-why-audiophiles-fall-snake-oil/
The problem comes partly also with these articles! They imply, we know already everything, and this is not certain obviously.
What are they measuring?
E.g.
“Consider speaker cables costing $10,000 when $20 hardware store alternatives measure identically. Professional recording studios (the ones producing the music audiophiles obsess over) use standard cables.”
This sentence say nothing, without knowing what they measure. Also, over the centuries, we saw many times that with continuous development, new knowledge of certain topic pours in and suddenly you begin to measure things that you didn’t know before and things become clear why it is like it is…
Anyway, this is not a “carte blanches” for snake oil topics…

The electrical properties of a cable for the intended application. The cable is transporting an electrical signal, no "magical" fairy dust. These measurements are simple and understood for a very long time now.
Completely true. Studios use standard cables.
A quote (don't know who said it)
"Every single bit of nuance and detail any High End Cable 'reveals' in an audiophiles system simultaneously proves that the standard quality cables used in the recordings were perfectly capable of transmitting that same signal."
If you want to know what is measured you can find that information, it's readily available. Ofcourse there have been many technological advances over time but mostly not in already solid established fields.This sentence say nothing, without knowing what they measure.

Most people who believe in snake oil lack the (technical) knowledge and are not willing to even try to understand. The people who sell the snake oil know they are selling just that. Those are the charlatans not the people who deeply understand the topics they are talking about.

This is only partially true about power supplies and routers. They can, of course, but they're often limited by the device's price. Otherwise, power supplies and routers of varying complexity would cost the same. And the charger included with the Pro Plus clearly demonstrates this. After all, aren't engineers the ones who design expensive devices?

The really good engineers are the ones that can design high quality units using already available low cost components.
These are the ones that understand what matters and what don't.

Absolutely right, who's arguing? That's why a $1 charger from AliExpress will charge your phone's battery just as well as a $100 iFi power supply for audio devices, regardless of the pulse level.

I strongly disagree there, a $1 charger probably can charge your phone but they usually cut down on materials, lack safety components, lack ICs for regulating charge and and rely in cheap and not really recommended ways of lowering and rectifying voltage, there is not just one way of doing it...they present a fire hazzard, at least don't leave them plugged 24/7, on top of that they will add more noise to your mains as for their lack or inferior filtering.

Well, it's hard to say. I bought a genuine Samsung power supply with Power Delivery on eBay for €8 including shipping. Well, maybe two bucks in China. We're talking about the most basic ones, without fast charging. It's entirely possible.

I agree there. It can be too cheap.
The art is to find the balance between cost and performance. Not including stuff that doesn't really matter, like XLR or LPS.
WiiM is doing a great job with that.

Indeed the fire hazard, a power supply going up in smoke and/or fire is a strong indication that the design failed.
Thinking about starting a bar list for sorting the members here for what I think they lean to be in BBT. A Sheldon, a Rajesh, a Leonard or a Howard. Hopefully enough Leonards are here. At the end he got the jackpot because of Penny

The power supply from the Pro Plus kit is not manufactured by WiiM.

Did it! But will keep it secret. You have got a mark too
