Hi,

has anyone tested iFi Audio iPower Elite? It’s a switching mode power supply but reported to have only 1μV noise.
 
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.

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.
