Allow me a longer quote from the white paper to illustrate Wilson Benesch's scientific approach to the technical challenges of designing a turntable component: “The primary objective of the FrACTal chassis is to establish a consistent and unchanging geometric relationship between the tonearm and the centre of the motor. To achieve this, a machined component is required that provides an external shape with unchanging precision. However, due to its size, such a structure is susceptible to vibrations. To address this issue, a two-piece design was developed. Each side of the assembly is machined from a single piece in a single operation, ensuring exceptionally high precision with tolerances of less than 0.01 millimetres. This critical geometry allows for no adjustments, as the geometric accuracy is fixed after the tonearm base is bolted in place. …

The geometric considerations are crucial, but the resulting structure was designed to absorb any energy from the environment. Through innovative fractal geometric damping techniques, the FrACTal chassis effectively prevents the occurrence of resonance artifacts by mimicking the energy absorption properties found in fractals in nature. The success of this design was confirmed by independent measurements at Sheffield Hallam University using laser vibrometers. Composed of 18 different materials, the FrACTal chassis represents a significant development. Wilson Benesch worked closely with Glass Technology Services (GTS) in Chesterfield…
