It’s like with any technical device! One person swears by manufacturer abc, another by xyz! That’s OK too! I prefer linear power supplies SBooster and Keces. For 4 years, a Keces P8 Dual has been supplying a Nucleus and the Melco Switch, to my satisfaction (sound etc.). SBooster supplies 10Mhz quartz oscillator! The less contaminated the digital signal is, the easier the signals are processed by DAC etc. "Digital signals are not just made up of 1 and 0 „

That hurts. Where is this funny theory from exactly?

It is, I believe the standard explanation for when people believe that whatever digital technology does to guarantee the integrity of the bit stream (error correction, and other stuff, like the isolation provided by a network architecture, etc) it is not enough to ensure faithful reproduction.
Basically the idea is that digital is not “real” - in the sense that the representation uses voltages which ultimately means everything is really analog.
So it is said that things like (specially) noise affect the transmission of those voltages and therefore cause audible degradation due to how that will affect the transmission of the bitstream.
It doesn’t, from what I know. So just the messenger here. Pls don’t think I subscribe to the notion.

Spot on. And to answer the “where from” part, I believe it comes from audio gear manufacturers, as they attempt to maintain the analog world status quo, where reproduction was done in real time, transmission noise did affect the signal irreversibly, and there was generation loss. That’s probably why the move to digital transmissions improved everything except audio 
(Of course, there is a discussion to have about the audibility of analog transmission artifacts and how many veils you can lift, but at least those artifacts are undeniable.)

The Ever-Changing Gospel of Digital Transmission
It’s also hilarious how the “gold standard” for digital audio keeps shifting, always just ahead of the last thing audiophiles spent a fortune on. Once upon a time, SPDIF was the problem child—jitter was the enemy, and everyone agreed USB was the savior. USB was async, it didn’t suffer from SPDIF’s clocking issues, and it would finally deliver “bit-perfect” audio without those pesky timing artifacts. For a while, USB was the only way to get a pure signal.
Then, suddenly, USB was out. It was noisy! It was polluted by power rail garbage from computers! It carried ground loops and injected harshness into your music! It was in bad need for various fixes that started as cheap tweaks and ended up costing thousands of dollars just to get the purest USB signal into your DAC. But then came Ethernet, now that was the real answer. Ethernet was galvanically isolated, asynchronous, totally immune to jitter, and handled packets with perfect error correction. It was the final frontier of digital purity.
But wait—turns out Ethernet isn’t perfect either! Now we need audiophile-grade network switches, linear power supplies for routers, and high-end Ethernet cables with cryogenically treated conductors, because of course they make a difference. And now, if your streamer doesn’t have fiber optic input, are you even serious about digital audio?
It’s like a never-ending shell game, where the goalpost keeps moving just far enough to make sure there’s always something “compromising” your setup—and always a way to get sleepness nights over and spend more money to fix it.

I spend my time nowadays focused on room treatment, active speakers and room correction. It highlights inane tweakery such as this for what it is.

And, if you can hear that, you get two stickers: “golden ears” and “resolving system”.
BTW, some people think the [current] golden standard is I2S. Same people probably think that USB is bad because of the number of devices on the market that attempt to “fix” it. Let’s wait and see how many I2S isolators/re-clockers are going to pop up.

Well, if people can be fleeced once, they can be fleeced again and again. Somebody’s gotta do it!
Uh, am I the only one waiting with bated breath for those alleged absolutely proving the LPS advantages studies that a vendor of “absolutely not printer cables” promised here last week?

I am using the SBooster for Nucleus One without any problem…

I’m sure you are, but that says nothing about the efficacy of an LPS used with a Nucleus or general purpose computer.

It’s just power, if it’s up to specs it will work, even if it does nothing to SQ.
Nevertheless, it won’t be good for warranty:

I wonder how strong my confirmation bias would be having spent 400 bucks on a superfluous power supply. It might though be that my mood would turn dark rather than the music‘s background.

In that case I would suggest you don’t buy one
This picture should really just end this discussion. Anyone asking about boutique power supplies for their expensive Nucleus One/Titan music server, just turn it over and heed the warning.

Sbooster BOTW P&P ECO 18-19V MKII is 18V / 2.25A, 18.5V / 2A so it does not meet the requirements stated: 19V /3,42A.
Could give you problems in the long run

And that was pointed out in post #10 of this thread.
Incidentally, some years ago I replaced the wallwart on my Allo DigiOne–because it was below spec and updates failed–with an “audio class” LPS I had in hand. It turned out that this was noisier than the stock RPi I now use.
