totaldac d1 USB A/B 1 Meter

The USB cable/filter is USB1 (12Mbit/s) and USB2.0 (480Mbit/s) compatible, it can carry pcm in synchronous or asynchronous mode or anything else, under Windows, MAC or Linux. It is obviously bit perfect.
The filter box embeds also a circuit to better protect your DAC from the possible over-voltages coming from the computer.

The filter/cable is made of more than 30 components and it is available in different length.
