About the CAD USB Control
The Computer Audio Design CAD USB Control is a small passive device that plugs into an unused USB port in audio components such as music servers, streamers, routers, network switches, and digital interfaces. It is designed to reduce high-frequency noise on the USB +5Vdc line and signal ground across a very wide frequency range, with the goal of improving timing, soundstage, rhythm, and overall musicality without slowing or altering the audio signal. The product is listed by CAD at $750 on the product page, while a later products page shows $825, so $750 appears to be the earlier or direct product-page price and may have changed over time. The device is described as thumb-sized and intended for any available USB or software-update port.
