Can you confirm the signal from radio to amp is good? Sometimes the fiber optic cable breaks in mysterious fashion. You can unplug one end at the amp and the other at the radio and put a flashlight to it on one of the ends and then check the other end to see if you can see the light. I hope you are successful as I want to upgrade again to the B & O amp.
