The Nº32 allows you to invert the polarity of the music to which you
are listening with the press of a button.
People vary in their sensitivity
to this aspect of the sound,
and the difference frequently ranges from
subtle to inaudible, depending on microphone technique and other
factors in the recording itself. However, some recordings simply sound
correct in one position, and irretrievably wrong in the other.
We encourage you to experiment with the polariy feature to see what
you think works best for any given recording, understanding that the
recordings themselves are anything but consistent.
