Linear Power Supply & USB devices

Streamer=RPI4, Allo DigiOne

DAC = Khadas Toneboard V1 

Bottlehead Crack Headphone Amp (fully upgraded) w/ Sennheiser HD 600

On a whim, I added a LPS to the RPI/Allo setup and was pleasantly surprised by the result.  It wasn't a huge difference, but well worth the $55 (used) I paid.  It's rated at 5v 3A which is perfect for a Raspberry PI && Allo DigiOne Hat.  

The Toneboard DAC is being powered by one of the USB ports on the RPi.  Will the LPS provide any benefit to the DAC being plugged into the RPI?

In my second system I use a Shanti LPS to feed my Allo streamer.  In my primary system I have 4 Farad LPS supplying my DAC and upscaler.  I have a generic LPS supplying my switch and I'm getting a 19V LPS to power my Roon Core, I don't expect much from the latter as that isn't the signal path.

Welll, @shkong78 I exaggerated.  I have ordered it and paid for it but haven't recieved it yet. 

I feel like I've been silly to buy the Farad PSU for the DAVE and left the M-Scaler on the switching power supply.  I expect it will be noticable.  I'll let you know when I get it.
