RoPieee quiter with silent DC supply for Raspi4

I’m using ROPIEEE-XL on a Raspi4 with DAC PRO HAT which is a bit noisy, wondered if a silent power supply would help (better than the original Raspi 5V/3A AC adapter)? Any experience here with that?

I have a couple of iFi iPower supplies for my Pi’s.
They work great, but I cannot say they improve the sound over my cheap and middle of the road power supplies to my hearing anyway.

One thing to consider is the current switched mode power supply likely doesn’t have a ground connector, and replacing this with another could introduce a ground loop.

I bought a ifi ipower x 5V/3A silent power supply and will soon be able to make comparisons.

No worries I live in Germany, we have a very well done AC network with proper PEN protected ground wire…
