The new CAD USB Filter replaces the USB I cable. The filter uses the same patented filter technology, developed in-house by Scott Berry, as is used in the new USB II-R cable.

Digital audio source components – from servers to streamers, from CD transports to laptops – are real noise pollutants in an audio system. Their CPUs, chipsets, switchers, power supplies, regulators, and the like generate significantly more high-frequency ‘noise’ than any analog component. To prevent this unwanted noise from degrading the overall performance of your system, it must be addressed before it reaches the analog stage.

The CAD USB Filter is designed to filter out this noise from digital music sources before it reaches the digital-to-analog converter (DAC). The CAD USB Filter simply plugs directly into a DAC/Streamer USB audio input and can be used with any USB cable.

The USB Filter is a B-end filter: with one female and one male B-type connector. Place the filter as close as possible to the DAC/Streamer.

The CAD USB Filter provides more clarity across all frequencies, a larger soundstage with greater speed, and improved timing and rhythm.
