The ABX will do. If you say you hear a difference and go on to ABX
a clip 27/30, that'll be statistical proof you really _are_ hearing
a difference and not imagining it.

My point was that one never should assume he is hearing anything
(wrong with an audio codec) unless it is verified by a proper blind test.
The power of suggestion is just way too strong.
