Thorens TD 903 Turntable
The Baby Sister of the TD 900 SeriesPaying homage to the legendary TD 150 and TD 160 models of the sixties and seventies, THORENS® has reinterpreted the sub-chassis turntable with a state-of-the-art, ground-up development using the latest materials. Highest fidelity and dynamics were our main priorities during the development of the new turntable series. However, we also placed great importance on user-friendliness, a timeless aesthetics as well as flexible configuration and upgrade options while retaining the traditional sub-chassis design.
New MaterialsThe sub-chassis is made of triCom, an aluminium/POM composite characterized by excellent damping properties and high stiffness. Its weight has been optimized for high performance. To reduce vibrations, the synchronous AC motor is mounted directly onto the damped sub-chassis. It drives the sub-platter via a machined precision belt.
New ArchitectureThe sub-chassis is suspended by means of three conical springs which can be adjusted from above in order to achieve uniform tension. The bearing is made of sintered bronze with a Tefl on® thrust pad and optimized for smooth running. The steel axle supported therein provides very low, constant friction and thus presents a uniform load to the motor. Two of the turntable’s three feet can be levelled from above, which facilitates setup. Depending on the model, different damping architectures, tonearm boards and platters are used.The design can accommodate a wide variety of 9” and 10” tonearms also from third-party manufacturers.
