Problem solved. How? I don't know. Tried an optical cable. That worked. The switched back to the coaxial and then that worked, too.
Do you believe there is a burn in period for the Nuforce Oppo?
Thanks for the help.
I don't think the burn-in on a coaxial is that dramatic

On the sound, they would need about 50 hours to sound really good, and continue to improve towards 100 hours. Due to the fact that there is no capacitor in the signal path, the initial burn-in would sound dramatic, and then the magnitude of change starts to taper off after 50 hours.
