through a Marantz Home Theatre amplifier before the TV. I had to return
this unit for repair a while back, so settings have been switched back and
forth between 5.1 and stereo, so I may have ended up with different
settings from original leading to the differences in volume. At least I
know where to start looking now.

Some Marantz amps have an automatic dynamic range compression and volume
levelling feature called MDAX or somesuch. That can mask the problem
remarkably well...
