That’s for sure!
I think the Nucleus One has a 2 year warranty from date of purchase.
Hello, here are a few examples of what a “clean” digital signal 1 and 0 looks like🤨
Measurements Ethernet 100/1000

Everybody knows this and it doesn’t matter because these voltage differences are converted to yes/no states in a transistor.

Well, it’s a bit more complicated than yes/no! I spent 30 years developing digital and analogue devices, and the biggest problem back then was the interference from the (cheap) switching power supplies! That’s why I have a mixed relationship with these devices!!

When reading the transistor state it’s what it is
The interference from an SMPS on a Roon Server did both or one of this?
- Cause digital bit errors in the server that you could detect? The bits going out were different from the bits going in?
- It created bit errors in the input buffer or signal distortion in the analog output stage of a DAC remotely across Ethernet?
Edit: besides, the server computer has various SMPS inside that split up the supplied power from the external PS to the voltages needed for the various subsystems.

It’s just that we made developments, for example machine controls, process processing, etc. Other companies installed switching power supplies in their devices and didn’t place much importance on shielding! Our developments worked perfectly in the workshop! When the machines/production lines were put into operation, malfunctions kept occurring! The problems only arise when the modules/controls from the different manufacturers interact! A German pharmaceutical/chemical manufacturer demanded “no switching power supplies” in tenders at the time. I think they already knew what they were talking about!
Anyone can do it wherever they want😉

They probably did, but the whole scenario is as different from the topic as it can be.

As others have said. Save your money. I went down the whole LPSU, gucci ethernet cables, even had an optical converter in the ethernet chain. All a load of ■■. I sold the lot and now buy bog standard wall warts to power my Roon ROCK (Intel NUC) and the USBridge. Zero SQ difference.

It’s important to try it yourself, not what others say! That’s the only way you can be satisfied!

That is certainly what the audio tweak manufacturers would say! Or, you can listen to science and engineering. If you were connecting your DAC to the NUC, there could at least be a theoretical reason to keep your NUC as electrically quiet as possible. I emphasize, theoretical. But if you are using a separate endpoint, there is no basis for using an LPS at the other end of the network connection from your streamer.

Actually, linear supplies are cheaper to manufacture than switching supplies because they’re less complex. Of course, those selling linear power supplies would argue differently, but I can build a linear supply using four or five components, whereas a switching (switched mode) power supply takes a good few more.
Moreover, the proliferation of the wall-wart shouldn’t be used as an argument for one out performing the other. It’s only half the story. It’s like comparing Bic with Montblanc!
Switching supplies make economic sense in consumer electronics because the input voltage is no longer an issue. What’s more, they are the perfect partner for general purpose computers because of the power requirements and fast changes in load. Linear is simply the wrong choice in this scenario.
Just because you can doesn’t mean it’s a good idea or, for that matter, you should try it.
We’re not talking about audio here. If we were, it would be a truly interesting discussion … conventional amplification vs NCORE etc.

I bought this with great results
I just found this on AliExpress:
NZ$232.02 | 100W ZERO-ZONE SUPER Linear Power Supply For Audio DC5V 7V 9V 12V 14V 15V 16V 18V 19V 20V 24V 28V 32V

Could you please provide any evidence on this?
Were you able to
a) measure actual differences or
b) able to tell which power supply (SMPS/LPS) was active in a blind test scenario?
Else it’s just anecdotal or opinion.

Yes I was able to measure the switching noise from the stock power supply and easily tell the difference in my system.

So I have to assume (as you did not restrict it) that you were able to tell whether the SMPS or LPS was active at any given time (without knowing which was on). Well, then I applaud you for being probably the first human to pull this off!
Some engineers will have to check their earlier takes!

Agreed, live and let live. So long as no one is trying to force you to whatever they subscribe to its a non issue.

j’utilise un Nucleus Plus avec un TeddyPardo pour alimentation . je pense qu’ils feront des modèles adaptés aux nouveaux Nucleus si celui dédié aux anciens Nucleus (Nucleus et Nucleus Plus) ne correspondent plus ; ce qui n’est pas forcément le cas . Ils répondent vite aux questions : il faut leur demander .Même s’ils sont spécialisés sur Naim ils font des alimentations pour d’autres appareils aussi . Tout mon système est Naim c’est pourquoi je me suis tourné vers eux .Je suis content du résultat final … mes oreilles sont elles capables d’entendre une différence ? Je ne sais pas .

This I would call a very impractical consumer mentality. It will consume a lot of your time and money. If I have to buy a new lawnmower, I am not going to buy the first product that the search engine comes up with just for the sake of trying it out. I am going to read some reviews, comparisons and recommendations by sources I trust and make a choice based on that.
You seem to imply that even if I deem the merits of a product properly debunked I should still try it myself? No thanks!
