The problem is not entirely the fault of those AVPs. Dolby specify that Dolby recordings and streams must be -18 LUFFS. That is low. So the AV 10 must normalize the level before outputting it, which the AV 7705 and 7706 did not.
To be clear, all D+M AVPs and AVRs follow the same protocol in the Audyssey based auto setup, that the unit would use testones at around 75 dB (I found it could be as low as 72 -73dB for the more recent models, so I guess it wasn't carved in stone. The AV7705, 7706 and the AV10 will do the same in this regard.
The idea is, after calibration, when the volume of those units are set to around 80-82, that is around 0 to +2 in the relative scale, the unit will output about 85 dB average at the MMP, so sort of per THX.
