Whether used in series (in-line) or in parallel, JitterBug significantly reduces contamination from RF generated by a computer, car, or other devicesJitterBug FMJ also thoroughly addresses environmental RF Noise taking advantage of this vulnerable interface.

The new metal case is the most obvious change, though even the seemingly innocuous hinged "rubber" piece covering JitterBugs output is crucial to JitterBugs improved performance. That little black "door" is RF-proof thanks to the material being substantially RF-absorbing Carbon.

Employ one JitterBug in series between any computer, smartphone, NAS, streamer, or car audio system and a USB input. For an additional sonic improvement, use the second JitterBug in another unoccupied USB portin parallel to the firstexcept with JitterBug FMJs front door closed.

A JitterBug in series with AudioQuest DragonFlys Black or Red always helps those wonderful creatures fly higher and faster. However, its best to experiment when putting a JitterBug in front of a DragonFly Cobaltwhich itself employs some of JitterBugs filtering, and so the two filters in series can help or hurt performance depending on specific equipment and context.

Noise reduction and noise dissipation are AudioQuest! One cant hear our modern worlds pervasive RF Noise itself, but the compromises it causes robs us of detail and contrast and outright buries so much subtlety. Fight back with JitterBug FMJ.
