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.
