Thanks for the offer of help but I resolved the issue. After working on the 987 for almost three days (with Denon Tech Support) the last straw was when the front left and right channels died.
I found the 987 user UN-friendly. The auto-setup, while very easy, set the speakers at levels that all but ignored the surround, surround back and subwoofer. After setup, the volume varied greatly from show to show, requiring constant adjustment. On a minor point, the OSD is too small when read from about 10 feet.
