”Revised and refined, and now clad in metal, AudioQuest's USB noise filter is still a compelling upgrade for portable DAC users.” ’Hi-Fi News’ – Editor’s Choice.

USB noise issues
Connecting your PC, Mac or laptop to your hi-fi gives the potential for top quality, digital audio. The problem comes about with the computer’s USB output. Because there’s so much going on inside a computer, there’s a lot of electrical noise – especially from the power supply. Electrical noise means distortion and that means you don’t get to hear your music at its best.

Problem solved
AudioQuest’s JitterBug FMJ solves the distortion issue by simply plugging into your computer. Discrete, dual circuit noise dissipation filters remove the electrical noise, giving you a cleaner, more natural sound.

Improved with Full Metal Jacket
Now featuring FMJ (Full Metal Jacket), the JitterBug is encased in a metal, rather than plastic body. The metal body not only makes the filter more durable but also helps further isolate the audio signals from RF electrical noise interference – giving reduced distortion. Another new feature with the FMJ model is the rubber bung. This effectively seals the exposed USB socket, when the filter is being used as a standalone, passive filter.

The perfect match for AudioQuest DragonFlies
AudioQuest’s popular range of DragonFly DACs (Digital to Analogue Convertors), transform your computer’s sound. Plug in the JitterBug and the sound is improved further still. Developed with the DragonFly range, adding a JitterBug FMJ maximises your DragonFly’s performance.
