Record And Playback Test

Daniel Hertz audio systems are calibrated to live music using the record play test under the personal supervision of Mark Levinson. While scientific measurements are basic to audio engineering, the human ear is the final judge. When a pure 2 channel recording is reproduced through an audio system with no EQ moments after it is made, and the artist(s) is (are) present, you find out what you really have. Here, Michal Lech, the Polish cellist, records with Daniel Hertz in Venice, Italy.
