The title says it all:
For the sake of tidiness, low noise etc, I would love to have a PSU that can power my RPI+DAC (5V at least 3A, less than that does not work in my hands) and my desktop amp (19 – 24 V, at least 3A) simultaneously. Does such a thing exist? Unfortunately the SilentSwitcher provides way too low current for my needs, but I love the concept!
- DIY or commercial. If DIY, something a newbie can build.
- Feed from mains or another PSU
- If it could work from a battery, extra points, but not necessary
Thank you and sorry if this is too obvious or too stupid

It is unlikely such a power supply exists. There might be some industrial 24V DC power supplies that have a 5V DC auxiliary output but they won't be particularly low noise and you would likely have to build your own enclosure.
I am also sceptical about the potential improvements. Your equipment probably already has internal linear regulators where it matters and switching regulators elsewhere.

More convenience than anything else.
Hm, that's a shame, i think many of us could make use of such a thing.
Danke!

You could check out MeanWell RD-125B. As said, it is an industrial switching power supply. The 24V output gives enough headroom for linear post regulation and the 5V output can be adjusted and then you could also use linear regulators and still be within the proper voltage range for USB. ADS-115524 is similar. It has internal PFC and universal AC input (for RD-125B you need to select the proper range), but here the 24V output is adjustable instead of the 5V one.
Or you start looking at suitable transformers for a DIY linear power supply.
Edit: I was confused by the EMC standards and datasheets written in different decades. Both power supplies pass the relevant standards for home multimedia equipment.

interesting... almost by coincidence i am about to build 2 of the SMPS DC FILTER P089ZB kits of Mark Johnson. In case of noise, do you think i could use them here?
(and this reminds me all this was for the convenience of one cable and one box and i could easily end up with several filters hahaha)
