Yes, it's at -10dB, a computed test signal from the Denon Technical CD, and 
looking at the waveform in CoolEdit2000 one can see the amplitude being 
modulated, while the original is perfectly constant.

The amplitude modulation is inversely proportional to the quality setting, 
it looks reasonable to me.
