A top-loading CD player with a belt drive system.

The drive section uses a belt drive system that incorporates the know-how accumulated through analog player design of CEC. This system stabilizes the rotational angular velocity of the CD, which was considered difficult in the past.
In the belt drive system, a motor is installed at a position approximately 7.5 cm away from the spindle that rotates the disk and drives it via a belt. This makes the pickup less susceptible to vibration and electromagnetic noise generated by the motor. In the motor section, a low-torque motor with greatly reduced cogging is adopted in place of the conventional high-torque motor, and thorough measures against vibration are taken.
In addition, by utilizing the moment of inertia of the stabilizer (70 mm in diameter, 300g in weight), the angular velocity can be changed while maintaining a stable state from approximately 500 rpm required at the innermost circumference to approximately 200 rpm at the outermost circumference.

The D/A converter is equipped with two Bar Brown PCMs 1796 for 24bit/192kHz, providing low distortion factor and high dynamic range.
This DAC is positioned as a part of the amplifier stage and is fused with the LEF (Load Effect Free) amplifier circuit. It uses a current injection circuit that converts the current output signal of the DAC into a voltage signal as quickly as possible. This circuit is completely free from the NFB loop and processes the signal in one stage.
The fully balanced signal processing enables high-speed, low-distortion transmission, and the circuit configuration of pure class A operation enables purer transmission.

Both balanced and unbalanced analog outputs are available.
In addition to the coaxial, optical and XLR Route 3, the digital terminals are also equipped with CEC's unique superlink terminals.
