Advice needed for an USB DAC

Do you also happen to have a plain old official Raspberry Pi power supply? If so, I would suggest that before you buy yet another power supply, you see if you can discern any difference between using it and the Allo Shanti in your new setup.

PS - be sure check out the video about grounding in audio over at amirm’s Audio Science Review. Grounding issues can spoil the performance of any system of multiple components no matter the quality of the components.
