Behavior remains identical but quantification in 24 bit mode considerably improves the signal/noise ratio, the dynamic and the stereo separation. The 1820 meets all our expectations. It takes full advantage of the performance made possible by 24 bit quantification.
Frequency response : obviously nothing changes as regards this setting.
Noise level : the noise level dropped below 140 dB throughout almost the whole audio spectrum! With the exception of two occasional incidents that remained.
