Diapasons d'Or Hi-Fi 2019, France: The best audiophile products.
The airborne sound comes from the speakers during playback time-shifted on the turntable. It stimulates
the vinyl and makes it vibrate. At the same time, the stylus and motor also make vinyl vibrate. Among these
unwanted vibrations, the low frequency range has the most energy and re-enters the pickup and affects
the playback quality. The Nasotec VEM(Vibration Extinction Mechanism) Record Clamp is designed to absorb
and remove these harmful vibrations and makes the playback more balanced and more detail.
In the two graphics below you can see the positive effect very clearly. Without the VEM Record Clamp,
the low frequency is overemphasized (several peaks) and the overall balance is absent.
