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?
