Is it true that Sotm SMS 200 still uses switching dc-dc converter?

I am using an ifi 5V iPower to power a RPi + DigiOne and Teddy Pardo 12V/4.5A and 9V/2A units to power fitPC3 and M2Tech hiFace Evo, respectively. The Schiit Eitr is powered by its own AC/AC wall wart. I am particularly interested in whether a JS-2, DC3 or SR4 could possibly improve the sound quality of the RPi + DigiOne combo. I understand that the best results would likely be obtained by powering RPi and DigiOne separately, but this is not the focus of this thread. Thanks, nbpf

What matter most for a SBC like Pi, as indicated by Barrows, is the switching dc-dc converter onboard.
