Audioquest Jitterbug Audioquest

For is a lightly used Audioquest Jitterbug USB Data & Power Noise Filter.

Details from manufacturer

Dual Discrete Noise-Dissipation Circuits

Reduces the noise and ringing that plague both the data and power lines of USB ports

Measurably reduces jitter and packet errors

Improves dynamic contrast, warmth and resolution

The Problem: All computing devices—laptops, smartphones, Network Attached Storage devices (NAS drives), media servers, etc.—inherently generate a significant amount of noise and parasitic resonances. Additionally, computers contribute a considerable amount of RFI and EMI pollution onto the signal paths—all of which can easily find its way onto your USB cables and into your audio system. This noise and interference has many negative effects. Noise-compromised digital circuitry increases jitter and packet errors, resulting in distortion that causes a comparatively flat and irritating sound. Noise-compromised analog circuitry also damages the sound’s depth,

warmth and resolution.

The Solution: JitterBug’s dual-circuitry measurably reduces unwanted noise currents and parasitic resonances. It also reduces jitter and packet errors (in some cases, packet errors are completely eliminated).

The Result: Clearer and more compelling sound, music, dialog, etc. A better audio experience.

Use one JitterBug in series (in line) with any computer and USB DAC (digital-to-analog converter).

Use an additional JitterBug in parallel with the first for improved playback performance.

Use JitterBug with other locally connected USB devices, such as hard drives, printers, and cameras, to effectively reduce audio interference.

Use JitterBug with USB-enabled network devices, such as routers, NAS devices, and streamers.

Use JitterBug with mobile devices into audio systems in the home and in the car.
