TH350 Turntable

Positioned at the core of the TH series, the TH350 balances mass, precision, and engineering restraint. It features a 350 mm platter and a double-layered chassis composed of aluminium and Nero Marquinia marble.

Magnetic suspensions isolate the upper structure, minimizing mechanical interference, while a decoupled drive system with a large flywheel ensures rotational stability. A screw-on clamp improves contact between the record and platter, enhancing focus and reducing resonance.

The TH350 delivers a detailed, dynamic sound with strong spatial definition—characterized by stability, tonal clarity, and control across the frequency spectrum. Tonearm and clamp are included.

Designed and assembled in Italy, each Thuono turntable reflects a long-term commitment to analog fidelity, structural isolation, and precise mechanical execution.

Technical Overview

Isolation & Suspension
The TH350 features three magnetic suspension modules that decouple the upper chassis—constructed from Nero Marquinia marble and aluminium—from external vibrations. Each module employs opposing magnetic rings and self-lubricating bushings to eliminate mechanical contact. Additional decoupling discs beneath the chassis further improve isolation across all axes.

Platter & Bearing System
The 350 mm aluminium platter is paired with a damping and antistatic layer to reduce resonances and surface noise. A polished spindle, running on a hardened steel sphere, minimizes friction and mechanical wear. The entire bearing assembly is engineered for rotational stability and long-term precision.

Drive System
A 140 mm flywheel, mounted on a solid marble block, enhances rotational inertia and absorbs motor vibrations. The DC motor is housed in a flexible damping mount to reduce rumble. Speed is regulated via a Hall sensor and microprocessor, with a rotation-speed encoder correcting for minor fluctuations—maintaining stable playback at 33.33 and 45 RPM.

Chassis & Structure
The double-layer chassis (marble and aluminium) adds mass and rigidity, with targeted damping at key mechanical points—platter, motor, and tonearm base. The result is a clear reduction in resonant behavior and improved transient reproduction, supporting a deep, focused soundstage.

Clamp System
The included screw-on clamp is made from bronze and aluminium with internal damping and an electromagnetic disc. It improves contact with the record surface, manages static, and helps refine tonal balance and spatial definition.
