The new innovative Tri-Balance suspended sub-chassis allowed the TD 309 to optimally distribute the weight of the turntable, achieving perfect balance in both mechanical and aesthetic terms. Form and function work in harmony to make the TD309 a turntable that is guaranteed to reveal the magic of analogue replay. Because the three-point suspension system is housed in the turntable’s feet, the plinth is considerably slimmer than that of conventional sub-chassis decks. Driven by a decoupled low-noise low-voltage DC motor via a flat belt, the precision-machined sub-platter supports the main platter, which is made from fused silica. A special contact ring reduces resonance in the main platter. The TP 92 tonearm, which was specially designed for the TD 309, uses an ultra-low friction bearing and an innovative magnetic anti-bias system with zero friction. The arm tube is made from rolled aluminium that is damped using random-mass-reducing technology. The brass counterweight at the end of the arm tube is double-decoupled, and the tonearm is so designed that its center of gravity is level with the stylus.

A new take on sub-chassis technology. No one can deny that Thorens has made a major contribution to turntable engineering in the form of sub-chassis technology. Now the next chapter opens. The novel sub-chassis system of the TD 309 allowed us to optimally distribute the weight of the turntable, achieving perfect balance in both mechanical and aesthetic terms. Form and function work in harmony to make the TD 309 a turntable that is guaranteed to reveal the magic of analogue replay.

Tri-Balance. Because the three-point suspension system is housed in the turntable’s feet, the plinth is considerably slimmer than that of conventional sub-chassis decks. It is manufactured from a single piece of MDF, a material that offers excellent acoustic properties and can be machined to very tight tolerances. This enabled us to adopt a no-compromise approach to designing and positioning crucial components such as the tonearm and the motor. The result is a perfectly balanced turntable.

The heart of the turntable. Driven by a decoupled low-noise low-voltage DC motor via a flat belt, the precision-machined sub-platter supports the main platter, which is made from fused silica. A special contact ring reduces resonance in the main platter.

Turntable and tonearm – a perfect match. The TP 92 tonearm, which was specially designed for the TD 309, uses an ultra-lowfriction bearing and an innovative magnetic anti-bias system with zero stiction. The arm tube is made from rolled aluminium that is damped using random-mass-reducing technology. The brass counterweight at the end of the arm tube is double-decoupled, and the tonearm is so designed that its centre of gravity is level with the stylus.
