This cable is intended for equipment with a conventional USB Type-A output and USB Type-B input, as commonly found on high-quality DACs and USB audio devices. The Performance USB A-B is therefore ideal for connecting a computer, laptop, music server or compatible streamer to an external DAC. Always check the USB connections on both devices before ordering.
