The Audioquest Jitterbug is a USB data & power noise filter that utilizes not one, but two independent discrete noise-dissipation circuits. So what does the Jitterbug do? To put it simply, it eliminates all the unwanted jitter (also known as ringing noise) that affect the data and power lines of USB ports. The Jitterbug also gets rid of packet errors which improve the dynamic contrast, warmth, and resolution of the sound output.
The problem with most source devices like laptops, smartphones, NAS drives and media servers is that they inherently generate a significant amount of noise and parasitic resonances that nobody likes. Moreover, computers emit a whole bunch of RFI and EMI pollutants onto the signal paths that can easily creep into your USB cables and into your audio system. What does it do then? It causes a lot of distortion which sounds flat and irritating to even an untrained and non-critical ear. Noise-compromised analog circuitry can damage the sound like crazy - ruining everything you like is its depth, warmth or resolution. The AudioQuest JitterBug solves this problem as its dual-circuitry measurably reduces unwanted noise current, producing clearer and more compelling sound and ultimately giving you a better audio experience.
