Just an update on my output level problem...

I am using the 975 in stereo mode. After talking with Scott the output level issue with the Sony Blueray player was solved by changing the Sony audio output mode from Dolby to PCM. In my testing on a DVD and a Blueray disc the volume level I was getting at 0db is now available at about -10db, which should give us sufficient headroom. On my system I consider the problem solved.
