CD transport with separate D/A converter and independent mechanism and control for complete non-resonance and non-vibration.

The chassis has a structure in which a heavy class non-resonant FRP base, an aluminum die-cast chassis and a mechanical part are integrally connected, and in addition, it is floating supported by a special shock absorber. This structure enables the heavy class base to intercept external vibrations and to receive reaction vibrations at the time of pick-up operation. Thus, high accuracy tracking performance is achieved.
In addition, it is equipped with a high-precision linear motor that maintains accurate centering by tapered chucking and minimizes mechanical vibration to enable quick access.

The tray mechanism is top-loading to eliminate the tray section with high resonance. In addition, the recess for disk mounting / removal is made into a ammonite shape to prevent turbulence.
In addition, 12 mm thick solid aluminum is used for the top panel, and by tapering the inside, external light which disturbs the digital code and air vibration by sound pressure are cut off.

The internal structure isolates and shields the pickup section, microcomputer section and power supply section for each block to eliminate electrical interference.
In addition, the chassis is coated with black paint on top of copper plating, which is desirable for sound quality, so that both thickness and sound quality can be improved.

The digital output is equipped with optical and coaxial terminals, and an ultra-high-speed LUX type with a transfer rate several tens of times higher than that of the conventional type.
The LUX type is connected using a special cable.

The power supply unit is equipped with 2 transformers that are independent of the signal processing system and drive system. In addition, the use of 10 independent regulators for each stage eliminates mutual interference.

High-quality parts such as copper plating, glass epoxy 70 μ thickness OFC pattern substrate and PC-OCC wiring material are used for all cases including capacitors, resistors, and transformer cases with sound quality measures.

The switches on the top panel are kept to the minimum necessary, and programming functions are performed from the included remote control.
