It is exceptionally expensive. While it may meet its rated ripple voltage, the real question is what practical benefits such a clean power supply would provide.
Still, it would be interesting to see it tested.

I found one: https://6moons.com/audioreview_articles/ifi-ipower-elite-12v/
Does anyone have similar experience?

Found one what? Babbling about back-lit veils were clearer? Where's the measurements?

1μV of noise over what bandwidth? Knowing one without the other is semi-meaningless.
One reason for doubt is if truly that stable and noise free from DC to light, at $300 and 60W it would sell like hotcakes in other industries where such 'pure' DC power is required!
The other is I am very skeptical when a company emphasizes "low emi" in their product literature, but one can not find any information on even which tests were performed.
OTOH: For most audio products in a normal/typical environment, any semi-decent PS of sufficient power/current will generally work.
btw: appreciate the correct usage of a lowercase Mu for micro. I often either forget or am too lazy.

From my perspective, the test method employed is wholly inappropriate to make any conclusions as to it's ability to filter.
It's kind of like testing an AC air filter on how small of a particle it filters without introducing any particles for it to filter.
That is to say it's not a totally useless test. It does test if itself introduced any degradation of performance.
Now, whether or not a power source needs to be filtered is an entirely difference discussion.

Unless tested on one is able to make an objective assertion whether this is useful or not. The manufacturer knows every detail of course but will not make such internal infor available to the public. That is always a dilemma.
If it made an audible improvement they'd show evidence of it. Why not do that? It would only increase sales.
Or send it here to ASR to be measured - independent third party testing shows it has benefit. Why not do that? Will only increase sales.
Instead, they send one for review to a muppet website, well known for promoting pretend upgrades, for them to write a page of favourable waffle about it.
So clearly it does nothing of any real benefit. No dilemma at all.

I just found this test result:

Number 5 is the iFi adapter of the previous generation. What’s your opinion?

Wholly inadequate. Nothing about how test was conducted, looks like another sighted worthless test.
Do you sell these iFi things? Affiliated in any way? You appear to have a vested interest.

You've answered your own question there. There's no dilemma, if the manufacturer wants to sell it into the market place it will do so using the best possible strategy to facilitate sales .. ... no actual information that's relevant.
Speaks volumes.
Now I'm off to put my densen de magic on , need to Demagnetize my diodes and caps in my TAD D1000 that sound exactly the same as my anthem STR pre amp .. that's digital for you .
I know how it is looking for reasons something might help, however the burden of proof is on the folks pushing it, not the ones with the hard earned! Something one would be wise to remember at all times ime .
