AudioQuest JITTERBUG FMJ (FULL METAL JACKET)
AudioQuest JitterBug FMJ (Full Metal Jacket)
JitterBug FMJ USB Data & Power Noise Filter
Many
tens of thousands of music lovers are already enjoying better audio
enabled by the original AudioQuest JitterBug USB Noise Filter—plugged
into cars’ USB jacks laptop computers USB “service-only” jacks on
Ethernet Streamers and more.
Now JitterBug FMJ with its Full Metal Jacket raises the stakes.
Whether used in series (in-line) or in parallel JitterBug significantly
reduces contamination from RF generated by a computer car or other
device—JitterBug 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 JitterBug’s output is crucial
to JitterBug’s 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 a second JitterBug in another unoccupied USB port—in
parallel to the first—except with JitterBug FMJ’s front door closed.
A
JitterBug in series with AudioQuest DragonFlys Black or Red always
helps those wonderful creatures fly higher and faster. However it’s
best to experiment when putting a JitterBug in front of a DragonFly
Cobalt—which itself employs some of JitterBug’s filtering and so the
two filters in series can help or hurt performance depending on specific
equipment and context.
Noise
reduction and noise dissipation is AudioQuest! One can’t hear our
modern world’s 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.
