In the current edition of the german paper "Audio" there is a test of the MC-12. Their reference was the MC-1 and so they compared the MC-12 against the MC-1.
The MC-12 easily and by far surpassed the MC-1 in all areas. Beside the additional features these were the top areas of sound improvement: More natural sound, more dynamic and direct sound.
Bottom line: The MC-12 is the new reference of Audio (Germany).
