On my Devialet 120 power consumption is absolutely identical regardless of the DPM Setting in the Configurator and Devialet’s claim of adaption to the musical content cannot be measured at all.
I don't see any conflict between those two statements. The conclusion that the power drawn from the mains should vary with the musical program does not necessarily follow from the description of DPM, does it?
Hmmm, I can't follow your logic. Please tell me how it is then contributing to "greater energy efficiency" if its drawing the same power from the mains?
Sorry, you're right, of course - provided you measure the power draw for a long enough period.
I measured the total sum of energy consumed over the length of an album and it was the same. But an easier test is a bonus track with a silent pause in the middle. You should be able to see an effect quite soon, even if your power meter would be too slow to register fast switches.
My guess is that some parts of energy savings are always active in 8.0 regardless of the DPM settings. But then the other promised part with content adaption is not yet active, because they were in a hurry and could not finish it before Munich.
I think the user is being fooled of having an option in the configurator (at least Devialet 120 owners).
