Try to find a Cal Delta transport to go with your Sigma
and bag the Toslink for a digital coax or balanced cable.
Once you get a digital inferface you like, bypass the input selector switch on the Sigma.
The Sigma circuit board is very easy to work on, better coupling caps, power supply caps, diodes and resistors will also give you a lot bang for the buck.
