Measurements not Revealing Significant Differences Between AVRs and AVPs

[PENG]

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.

I can tell you that on the 7705 and 7706 Atmos stream played at a low level. it was a nuisance as you had to remember to turn back the volume after playing an Atmos source.

In addition the AV10 auto selects Atmos, the others did not.

On the BPO streams, if an Atmos version is available there is a star icon lower left. With the 7705 and 7706 you had to click on that and a sub menu appeared and then you had to select two channel or Atmos.

On the AV10 if an Atmos stream is available then it auto selects it with no further action required.

On the AV10 the two channel and Atmos stream play back at the same level, which they did not on the 7705 and 7706. Honestly I am glad to be rid of those, yes really glad.
