Advanced USB Digital Interface

The Singxer F-1 digital interface allows you to connect your DAC or receiver to your computer using coaxial. This will come in handy for audiophiles who want to bypass DACs with outdated USB interfaces, or those incompatible with their current setup. The F-1 connects to your computer using the highly regarded XMOS XU208 chip, which uses a more advanced process technology than previous XMOS chips. The device is powered by USB and requires no external power source to operate. Finally, it’s compatible with Windows, Mac OS X, Linux, and Android with the installation of a driver. A USB/coaxial cable is not included.

Note: At checkout, choose the F-1 with a case (base price) or the F-1 without a case (- $25).
