To solve the problem of torsional forces, some manufacturers build a rigid turntable and completely eliminate the suspension. But vibrations produced naturally by mechanical components and the environment are fed back to the platter and tone arm, causing yet another type of blurring and distortion of the music signal. The resulting sound is often described as harsh, aggressive and glassy.
While endless research into alternate materials has been beneficial in improving the sound of rigid turntables, because the platter and the tone arm are not isolated, vibrations can only be controlled, not eliminated. Additionally, the proposed design solutions create expensive, heavy and complicated turntables.
Dual Platter:
Kronos is an innovative turntable that breaks the rules of conventional audio design, earning the reputation of being the first of its kind. It employs two identical high mass platters, one above the other rotating in opposite directions and moving at precisely the same speed. This engineering completely eliminates torsional forces. Since the turntable is protected from mechanical and environmental vibrations, it can therefore be suspended without any negative outcomes. Finally, the judicious use of materials helps minimize the transfer of remaining mechanical vibrations emitted from the bearings and stylus friction. The result is a turntable platform with unparalleled stability. A solution so innovative that two separate patents applications are presently pending with more to come.
Motor Drive:
Kronos uses two high quality Swiss-made DC motors that consistently deliver quiet, smooth, linear power to the platters. DC voltage to the motors is produced from a fully regulated CLASS A dual power supply, CPU-controlled to maintain constant speed. The Kronos’ controller does not use pulse width modulation, as this method of control produces jerkiness in the drives. Instead, the CPU controller receives speed readings from the platters via optical sensors and adjusts voltage to each DC motor in real time. Speed stability is therefore guaranteed over the life of the turntable, regardless of environmental factors, belt stretching or mechanical wear.
Bearing:
When designing and building the two bearings of Kronos, our objective was to provide the most quiet operation possible while maximizing service life. Our in-depth design process included extensive research of base metal alloys and vapour deposit coatings within the aerospace industry. We also inverted the bearing design to place contact in the rotational plane, successfully reducing torque induced drag. We also included double hydraulic insulation to provide the ideal dampening properties. The result – The lowest noise floor we have yet encountered in an audio turntable.
Every single component of the Kronos is engineered for simplicity and ease of use: the uncomplicated construction enables easy set-up, smooth operation and long-term reliability. This straightforward design allows the focus to remain on superior sound delivery.
Every Kronos turntable is entirely hand assembled and duly adjusted and tested before it is shipped to you. It is protected in its custom built flight case. And it is very exclusive. Only 250 Kronos turntables will be issued in its first version.
