My spirits sank as I read the comments on Stereophile
's Facebook page. In the November issue, we had published reviews
of UpTone Audio's USB Regen device by Kalman Rubinson, Michael Lavorgna, and myself. Michael and Kal had enthused about the positive effect the USB Regen had made, but I could detect no measurable
difference. On Facebook, Dan Madden had written, "I think a device like this would need a blind listening test to verify that a listener could hear the difference in a statistically measurable way, in a very high percentage of times."
