Det anerkendet amerikanske Hi-Fi magasin Stereophile har haft luppen fremme i en større test af ifi´s PRO iDSD, her er et par ord:
"Bottom line: iFi Audio’s Pro iDSD lived up to the hyperbole of its owner’s manual. It did actually play music like “a ‘state of the art’ reference digital to analog converter.” It did indeed sound like “an all-out assault” on what is possible in DACs today . . . and it did both of those good things at a ridiculously low price. Highly recommended".
