Pat's test proves that there is a difference in the noise spectrum, the AudioDiffmaker tests (and my ears for what that's worth) imply that it is not audible according to the normally accepted paradigms - non-correlated "pink" noise at -80dB or lower is not easily heard. The consensus is that to REALLY make an audible (as opposed to measurable) difference to the analogue outputs, one would have to disembowel the device and remove that internal switching supply. For the adventurous amongst you, try the ADF hearing test - can you hear the hidden marching/brass band in the background of the classical piece?
