http://www.AudioAsylum.com/audio/tweaks/messages/48709.htmlPerhaps you were not aware that he was manipulating the graph ranges thus? In addition, as I posted, his measurements are suspect anyway, as many people have not seen such a clean 5532, nor have they seen such a dirty 2604. His use of extra PS bypassing for the 5532 and NONE of the other op-amps also seems quite suspicious.
Simple whole number THD measurements DO NOT tell the whole picture.
What matters is what the various op-amps sound like when actually used in a real world circuit.
