The Dual Core is designed to work with analog, computer, and digital input.
Here is DSPeaker's reason for using optical rather than coax as taken from the FAQs page:
Q: Coax s/pdif (RCA) sounds better than optical tosink in our ears and due to the listening tests we have done in the past. So why use optical?
A: Our system does not derive its analog to digital converter (DAC) clock from the digital input(s), so jitter in the input is not a problem. Ant jitter in the input gets removed in the process, so there is no difference between the quality of coaxial and optical input in this respect.
The huge advantage of using optical is that there is no ground connection between devices.
Thanks for the encouagement :-). If I can't find a good converter I may stay with my trans/dac combo and use the line level input.
