The X-01 D2: the flagship of ESOTERIC’s “X” series integrated
Super Audio CD/CD players opens a new realm of audio reproduction.
The X-01D2 incorporates ESOTERIC’s P-03 series VRDS-NEO mechanism
and the world's first user selectable dual D/A converter system.(*) This new audio system includes
a proprietary DSD/PCM and PCM/DSD interactive signal conversion function.

ESOTERIC’s uncompromising technologies include the proprietary VRDS-NEO
(Vibration Free Rigid Disc-Clamping System), used as
a core mechanical design helping to re-define sound quality.

ultra-low vibration and extremely accurate data retrieval
The P-03 VRDS-NEO mechanism, enhanced from the original X-01 mechanism, is an integration of ESOTERIC’s
highest grade “mechatronics,” technologies, providing the ultimate experience in sound reproduction.
TEAC proprietary hall element sensing-type three-phase brushless motor.
Shaft-sliding pickup structure keeps the laser optical axis in a precise vertical
orientation, eliminating the need for off axis error correction.
Ultra-high-precision turntable system
When a Super Audio CD is played, the higher-speed rotational requirement causes
increased and unwanted vibration. The VRDE-NEO turntable precisely supports
disc rotation so adverse effects generated during high-speed rotation can be
minimized. High-speed rotation also necessitates that the spindle shaft be more
rigid than in the past. The turntable, which may be considered the heart of the
VRDS-NEO mechanism, is supported by high-precision, highly rigid mechanical
components.
[Coreless motor with no rotational irregularities]
ESOTERIC has developed a long-life three-phase brushless spindle motor for high-
speed rotation. Development of the magnetic circuit, consisting of a neodymium
magnet, was completed through numerous tests and scientific validations
including magnetic field analysis. The optimized magnetic circuit minimizes
rotational irregularities in the motor and makes it possible to reduce fluctuations in
the motor drive current, thereby lessening any adverse effects on audio circuits
and other areas.

[Duralumin turntable]
During Super Audio CD playback, the maximum rotational speed is 4.5 times
greater than the rotational speed during conventional CD playback. In order to
ensure that the turntable can handle this high-speed rotation, ESOTERIC selected
duralumin as the turntable material. This material is best known as a body material
used in high speed aircraft. ESOTERIC developed new technology for processing
this material into lower mass with higher dimensional precision. As a result, the
P-03 enables ultra smooth turntable response and stable data acquisition by
preventing disc vibration. The turntable is dyed black to absorb any diffused
reflection of the laser from the pickup device.
[Rigidity and precision are significantly improved by the use of highly
precise ball bearings in the spindle shaft bearing assembly]
A pair of precise ball bearings is used in the
spindle shaft bearing unit and a pre-load is
applied to the bearing inner rings. This design
significantly reduces any potential for rattling
and shaft shaking during use. The use of these
specialized ball bearings dramatically increases
the precision of the bearing unit, and greatly
improves rotation and positioning accuracy. The ceramic ball bearings support
smooth and precisely controlled turntable rotation from low speed to high speed.

[Massive bridge unit to support the turntable and the spindle unit]
The X-01D2 features a 20 mm-thick ultra high mass bridge (1.7 kg or 3.75 lbs),
precisely processed from SS400 steel. This bridge rigidly supports the turntable
and spindle unit. Any vibrations originating from the spindle during rotation are
subsequently attenuated by the mass of the bridge.
Advanced pick up technology --- thread servo section
ESOTERIC developed an ingenious component structure for driving the pickup
lens using a horizontal sled structure. This design moves the pickup unit with an
extremely high level of accuracy. This system ensures that the laser optical axis is
always positioned at the very center of the pit track for optimal reading, making it
possible to minimize the adverse effects of disc surface shaking and offset tracking
often present with higher speed rotation.
[Pickup structure designed to
prevent laser optical axis tilting
during lens movement]
The pickup used in the X-01D2 has a
shaft-sliding structure that prevents the
laser optical axis from tilting away from a
vertical orientation even when the lens
is moved. This stability in the optical axis
pickup and vibration-free VRDS turntable
combination, are the primary factors
defining the outstanding mechanical performance of the X-01 D2.
[Speed feedback-controlled sled transport with superior response and
minimal extraneous pickup lens movement]
To provide a very high-performance pickup capable of smooth, continuous
movement, a proprietary hall element sensing-type, three-phase brushless motor
is used in the sled transport. Powerful electronic speed feedback circuits control
this sled mechanism. This is another design implementation that improves the
precision and accuracy of the data acquisition process.
[Vibration isolation for spindle motor and moving sled systems]
The spindle system, which may generate fine vibrations during rotation, is isolated
from the moving sled system. Since the sled mechanism requires very delicate
electronic control, this isolation from high-frequency vibrations ensures superior
data reading performance.
[High-precision mechanism and new software controlled servo control for
superior playability]
The precision-machined proprietary mechanism combines with new system
software to provide optimal servo control for each type of optical disc. This
equates to superior playback capability regardless of the type of disc used.
[Disc tray shutter mechanism – Vibration seal]
When the disc tray is closed, the shutter seals the front tray opening. As a
result, the shutter shields the internal mechanism, reducing any mechani-
cal or sound pressure vibration induced by external noises (such as those
created by loudspeakers). The vibration seal also stops airborn particles
from entering the system.
