The Vibration Equation:
Considering that turntables produce sounds from vibrations etched into the record, vibration is everything to the turntable/sound quality equation.
Ultimately, you want vibrations from the needle only. This will provide the most accurate reproduction of the original recording. However, turntables are made by moving parts and exist in environments with moving elements, and movement means vibration!
Therefore, turntables are design to mitigate vibrations from both their internal moving mechanics and external influences like speakers and even people moving across floors.
INTERNAL VIBRATION MITIGATION
- few moving parts
- higher quality materials that dampen/eliminate resonance
- design principles that decouple vibrating parts (motor) from the needle
- design principles that brace parts to create rigidity and reduce resonance
EXTERNAL VIBRATION MITIGATION
- additional weight absorbs external vibration
- vibration dampening feet
- suspended plinths/platters
- cone-point feet (less surface contact)
There are a myriad of ways to reduce vibration and therefore reduce its colouration effects.
