Check to see if there is a software update. My onkyo reciever had one and the clicking was reduced alot.
Integra DHC-80.2 Audio Mode Click
Likely a long shot. When my DHC-80.2 pre/pro clicks through different audio modes seems to have a loud clicking sound. For example, when a BRD is played, there are various audio formats for the previews and feature. When the device detects the different formats (stereo, Dolby D, etc) the clicking seems overly pronounced. I had a DTR-80.2 Receiver which did not make these sounds.
Like I said, a long shot but it's troubling.
