Actually, there’s plenty of doubt. I’ve not seen any objective evidence backing up this assertion.
Lineair power supply

So you've provided an example how people tend to believe what they "Wish" to be true.
Some people say that an LPS is always an improvement. Some people say that the difference is even bigger for higher quality equipment. Let's verify the second assumption for the noise level on the analog output when device is idle.
Mini vs Pro vs Pro Plus
Pro Plus charger vs the cleanest power source I can provide - linear regulated batteries
Mini:
Whatever I use, results will be noisy.
Pro:
Visible differences, no noise for lps.
Pro Plus:
Visible differences again, no noise for lps again. But, the difference is smaller when compared to the Pro. Better device, better filtering on the analog output stage.

So, can I say / ask what I *think* the graphs are telling me, and you can correct me?!
The regular power supply is a little noisier than the battery power supply, particularly around mains frequency (50 hz) and multiples of that?
The db numbers for both are way quieter than anything I'd ever hear?
The difference on the pro plus, being the 'higher quality' item here, is not bigger - i.e. a higher quality device is possibly actually less 'improved' by a LPS?
In fact the regular power supply is much much noisier itself. You can see above the impact of the power supply on the powered device. It's not about the noise of the power supply.
I would say so. But as it's about the noise for an idle device, you can hear it if you amplify the output hard enough.
Yes.

I am using ifi ipower x and ifi lan silencer with wiim pro plus. The favorites of @onlyoneme 
Yeah, I really love their color and the designI am using ifi ipower x and ifi lan silencer with wiim pro plus. The favorites of @onlyoneme
Thank you for remembering me.
Ignoring 50Hz and 160Hz, GaN and linear power supplies look the same.

A special gift then, some samples captured on the Pro Plus powered by the stock charger vs a GaN charger. As always no hint which folder is for which charger.

I don't think I'll hear the difference, but I'll try tomorrow. I'm going to sleep with earplugs today.

@onlyoneme nice, thanks. Can you also show the differences (or lack of) when playing 32 multitone like this?
There is nothing to talk about, Pro Plus, 1/3 octave interval:
I prefer NID test tones instead, but almost no difference here:
And this is a case with the "worst" vs the "best" PSU.
double measures displayed simultaneously can be really awkward...we can't really understand what's going on in red for example
this approach sometimes has its limits...
;-)
The same as in green except small differences which are visible because green is on top for the second graph.
