This was the solution adopted after I figured the bisikek transformers were wildly overpriced.
Sowter btw has been going for decades making transformers that just work in mostly mumetal.

All the more exotic hype for nanocrystalline stuff = more hype for imaginary effects, while in the meantime people like us are CREATING the recordings you are listening to....microphones, DPA, Neumann, Gefell etc etc through a studio mixer and ADCs full of opamps.

The only worry I have in my CM4 - on a high quality swiss made board btw is RFI.
RFI from the wifi, and RFI from the 4G - LTE M.2 modem.
Both sources are switched to external antennae, something they missed on the RPI5, and another stupid thing...

The CM4 runs off car /24V or battery power because it's able to be fed with 9-28V DC.

The waveshare CM4 (power thru 5V USB-C) and Rpi5 systems can't do that - so maybe you're just listening to PSU noise?

(I happen to know that cos I have 2 waveshare boards plus the official CM4 9-28V one and a retroflag 2 GPI with Kodi + headphone output which has an onboard 4hr lithium battery and a CM4 inside.

BTW I thought the Swiss were known for making great watches. Oh wait, several of my Swiss watches have failed yet the Japanese watches keep on keeping on. Maybe your Swiss made CM4 PCB has too many Swiss cheese like holes in it?

  "I thought the Swiss were known for making great watches."
  
  Swiss watches?
  they do indeed make super watches...only about 90 mins from where we are now..
  which is why of course I am wearing one of them now..(a rare blackface Longines auto) more than 45yrs old - which is brutally mistreated most of the time).
  
  Maybe you didn't get your watches maintained by the right people?!
  (I get mine cleaned and worked on in Russia.)
  
  As for the Swiss TOFU board, not only is it by far the best IOT board out there, but being 2-3x of the price one expects and gets proper support + a superbly made product. They are releasing an even better one now.
  
  I have just finished cleaning the thing of dust build up +it has done 4.7TB over 4g this year alone as a router, file server, DSP, + loads more tasks/database/docker and more.
  
  The only thing that has gone on it in 12 months has been a CM4 chip which died.
  
  In an attempt to diss anything of quality, all you manage to do is to look incredibly stupid.
