In Reply to: RE: RPi-4B and Power ?? posted by tvr2500m on January 13, 2021 at 11:42:54
For my Main (Critical) Listening System, I use a Linear Power Supply. I got mine from Swagman Labs.
http://www.swagmanlab.com/Product_PSU?product_id=631 -- I have a couple of these. The Base Model costs around $160 -- The 'Signature' Model is around $300....
I assume you are using the USB output into a DAC? -- If so, I would not worry about 'Cleaning Anything Up'... I would however advise against powering a USB Drive from the Rpi (For Critical and your Main Listening System). I Would get a NAS for this purpose.
If you want to use a Coax Output from your RPi, I would look at the Allo Digione 'Hat'
I use both the USB Output and the Digione Coax Output into my DAC. In fact I have both hooked to my Same DAC on my main system, so it is easy to switch back and forth. The USB output can play DSD, while the Digione Coax output cannot.
Follow Ups:
I don't see the Pi USB connector in there though the 5V 3A works.
How much did this improve the stock powersupply. Currently I use the Argon 5.25V 3.5 Amp so I can drive the USB3 for a SSD boot and run LMS with the music Library. Seems as good as ethernet from a full Win 10 PC harddrive but I have not had recent time for critical listening.

"I don't see the Pi USB connector in there though the 5V 3A works. "The will make the cable any way you want. Just specify that you want a Micro-USB Cable to fit into the Model 4 Raspberry Pi.. I've got Cables that Fit Model 3 and 4 as well as the old Squeezebox Touch.
