Kal Rubinson has posted a review of the iFi iPower power supply ($49) in his Music in the Round column at Stereophile. His conclusions:
“Recordings with open, ambient soundstages sounded cleaner, and both instrumental and vocal music was more distinct. This was no major change that struck me every time I listened, but it did make all of my listening much more relaxing—perhaps because, subliminally, it required less effort to attend to individual sounds, particularly those far back on the soundstage.”
