Great sounding USB>Spdif (BNC) convertor. I bought the assembled board from Lucian and made a nice metal case for it, along with +5V power jack and neoprene pad. It's not the latest WaveIO model with the NDK clocks, but it was still a great model before that. Should beat 90% of the built in USB modules used with highend DAC's. $50 FIRM, it's a great value. I'll email you the driver for Windows OS.
