AudioQuest - Jitterbug USB Data & Power Noise Filter
If your music or audio source is a laptop or a computer then the Audioquest Jitterbug helps improve the sound of your digital music.
The Problem: All USB 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.
