I want to connect my Raspi B to an external DAC by SPDIF or TOSLINK. So I wonder which digital output board are you guys using whith your Raspi B.
It would by nice if you can share your experience. Which board, which outputs are available on this board (SPDIF, AES/EBU, TOSlink), transformer or transformerless, suppurted output formats etc.
I have have used the Wolfson Audio Card successfully for this application. It has one SPDIF out (Coaxial Type Connector). The model that I have clips together for the RPI B (not B+). Sound quality is excellent for the money.
