Jeff Dorgay has posted a review of the AudioQuest Jitterbug ($50) AT TONEAudio. His conclusions:
“The sound quality of cymbals, violin and piano is the most profound example of the JitterBug in action. Vocals become more palpable and realistic, with much more body and dimension. It’s not so much like cleaning a dirty window, but giving one more round of cleanup to a window that still has some streaks after the first round. Every time I thought the JitterBug wasn’t contributing to the sound of my system, it only took removing it for about 30 seconds for the harshness to return.”
