When comparing on and off settings when watching a movie the reduction in dynamic range is not subtle so compression settings seem to be quite extreme. If this also happens to music when it is on by default this is not good. Most people who are not happy with firmware 8.0 don't seem to complain however about dynamic range being reduced but more about music sounding more digital/harsh. So this is not likely to be the full explanation.
As far as I know not officially. My guess is that the Devialet somehow is able detect dynamically if there is a voice or not. When they detect the voice the signal stays the same (at least I could not hear any changes in my experiment sample), but when there is no voice the higher frequencies are reduced, hence quieter. So I think its not a compression while playing voices, but I am not sure. The effect is certainly dynamic and dependent on the content.
