For all, who won't believe in it:
This PSU tunes your sound! Needed new PSU for RaspberryPi 3 B+ and Hifiberry Digi-HAT, because of "undervoltage". Old PSU was made by iFi, 2.5A...
Spounds good, "undervoltage" made Pi geeting hot! The Allo supplies enough power. No "undervoltage" anymore. Sound gots smoother and more space. Very important: check mains phase or loose soundquality. Just turn mainsplug and listen... Have fun
