Commentary
A CD player developed by inheriting the construction of Integra C-729, a high-end machine.
In principle, the D/A converter uses a high-precision single-bit system that does not generate 0 cross distortion.
Harmonic distortion is reduced by differential operation of two independent L/R DAC circuits.
The pickup drive mechanism uses an original linear motor mechanism that realizes high-speed access and high tracking performance.
In addition, the tray is made of aluminum die-cast to increase vibration control, and the entire mechanism is shielded by a steel case to effectively block electromagnetic noise generated by the pickup.
Equipped with a digital servo system, every time a disc is loaded, error signals due to eccentricity or warpage are detected and fed back, and tracking, focus, offset, and gain related to reading accuracy are automatically controlled to optimize values.
The power supply is equipped with an AEI (Anti Electromagnetic Interface) transformer that reduces harmful magnetic leakage.
In addition, the constant voltage circuit is composed of two stages for the analog type and three stages for the DAC type to improve stability.
Wireless remote control is included.
