Sigh..In other words, it simply meant preference.

Averaged THD or isolated single tone spectra are not particularly useful for providing a complete picture when the objective is listening to music. Individual tests, however, on tones have proven differences that would suggest a mechanism behind the audible differences.
THD is irrelevant to the discusion. You tests obviously seem better than the single tone tests presernted here, could you reference some of them, afterall you said it had been proven long ago?
