VRDS mechanism for Super Audio CD players, incorporating a duralumin turntable and a SS400 bridge

The VDRS mechanism completely eliminates any vibration caused by the disc itself, thanks to the full-diameter clamp, that clamps the disc securely to the turntable. Additionally, warping and other defects of the disc are eliminated. The constancy of the reading angle between the optical pickup and the disc pits is therefore increased, and read errors, together with the occurrence of timing errors to the clock circuit, are significantly reduced.

Playback of Super Audio CDs requires high-speed rotation and a high degree of precision, and the X-03 accordingly uses a duralumin turntable. The bridge employs a pair of precisely engineered ball bearings, and is constructed of 10mm thick SS400 steel.

Coreless motor with neodymium magnets

A newly developed three-phase brushless spindle motor provides the fast and accurate turntable rotation required for Super Audio CD playback. This, coupled with the clamping turntable and the precision ball bearings, eliminate irregular rotation and vibration.

Neodymium stabilizes the motor’s driving current, reducing influence on the audio sections of the unit.

Constant-angle optical pickup mounted on a sled with feedback-monitored speed control

By mounting the pickup on a sled whose axis is rigid, the pickup lens is maintained at a constant angle and the laser beam, and hence the optical axis, is maintained in an accurate vertical orientation. An Esoteric original three-phase brushless motor with hall element detection drives the sled, and the speed of the sled is monitored and used to control the sled itself in a servo feedback operation, meaning the sled is highly responsive and smooth in its operation.

Sturdy, rigid chassis with triple-point pinpoint foot support

The unit is constructed with a 5mm thick robust steel base plate, and is divided into three logical sections, thereby reducing interference between components of the unit. Highly rigid mounts are used for the VDRS disc mechanism.

To eliminate vibration, three solid (tool steel) feet support the unit and isolate it mechanically.
