John Atkinson has posted a review of the AudioQuest JitterBug USB noise filter ($49) at Stereopile. His conclusions:
“You can see from the “Measurements” sidebar that I could find no significant effect that the JitterBug had on the analog signals output by three of the DACs I had to hand. Yet with those DACs and others, I heard an improvement in sound quality that I can attribute only to the JitterBug. I hate when that happens!”
