Oswalds Mill Audio K3

Type: Direct drive turntable system.

Drive Method: Direct drive with an ultra-high torque motor featuring neodymium magnets, more powerful than any used in previous turntables, including the Technics SP10 and Neumann units.

Platter: Middle-weight platter (approximately 14 kg) designed to provide the correct load for the motor and bearing system.

Speeds: Supports 33 1/3 and 45 RPM playback, with potentially 78 RPM available with additional setup.

Wow and Flutter: Extremely low due to the advanced motor control system, ensuring dynamic speed stability.

Rumble: Minimized by the design and construction, including hollow chambers filled with a special liquid for vibration damping.

Tonearm: Custom-designed Frank Schröder tonearm, forged using selective laser-melt technology and manufactured from 3D-printed components.

Suspension System: The plinth is made from cast iron with a ceramic finish, featuring hollow chambers filled with a vibration-damping liquid. The structure is grounded via one point to allow energy to be transmitted away from the turntable.

Bearing: Main bearing features a 117mm active length, 25mm diameter stainless steel shaft rotating in an optimized oil film, with an inverted thrust bearing maintaining atmospheric pressure.

Dimensions: Not specified, but the K3 is described as a large and heavy piece of equipment.

Weight: Not specified, but likely substantial due to the cast iron construction.

Power Supply: External power supply, with options including a vacuum tube-based DC power supply.

Additional Features:
Digital controller with over 1000 hours of R&D for precise speed control, allowing firmware updates via USB.
Compatible with various cartridges, though typically sold with a Soundsmith moving iron cartridge.
Available with a proprietary stand housing the power supply components
