Never heard of such a thing with the Benz. As others have mentioned, only if you wire it wrong in the head shell. If your phono or line stage preamp has a polarity switch, experiment with that to see if you notice a change, for the better. I noticed that on some music the playback sounds very flat and little lifeless, nothing like switching the phase on the preamp to take care of that. You will notice out of phase music by this certain flatness and lack of dynamic expression. Once the phase is correct, all harmony in the music life will ve restored. Good luck.
