The AudioQuest Jitterbug is an in line USB filter designed specifically to deal with noise on the USB line which can be a serious problem with music systems.
Connect it between a computer and a USB DAC (like the Dragonfly) to help reduce unwanted noise from the computer getting down the power and signal conductors to the DAC which can be incredibly sensitive to this type of noise.
The Jitterbug needs no software so it can be used with nearly all USB – DAC combinations and any computer or mobile operating system.
Highly recommended for any serious music listener who uses a USB connection to their DAC.
