SONY CDP-XA55ES (1998) | Current Pulse D/A

 

The XA-55ES was the last CD player in the ES series equipped with a variable digital filter and enhanced power supply. In this model the pickup is fixed to a solid base and the disk moves on the mechanical base, so that vibration of the pickup is sharply reduced and the current required for servo operation is relatively slow to compensate for disk distortion and eccentricity. In addition, the CDP-XA55ES uses a zinc die-cast base for fixing the optical pickup to reduce the resonance of the base itself and improve the reading accuracy. The CDP-XA55ES also uses a BSL motor for rotating the disc, which has less rotational unevenness. It is equipped with a 24-bit variable (VC) digital filter that can change the cutoff characteristics and subtly control the atmosphere of music. The new 24-bit filter improves the processing power and reproduces higher definition sound quality. In addition to the conventional standard position, five types of positions are available: clear, plain, fine, and silky. You can select the optimal position according to your audio equipment, room environment, and song. The XA55ES is a High-quality design using "current pulse D/A converter" and "triple R core transformer" The "Current Pulse D/A Converter" has a stable and clean current source, and is not affected by voltage noise from the calculation circuit, allowing it to reproduce expressive low frequencies. In addition, the iron core of the transformer is seamlessly shaped, and the cross section is made into a circular donut shape, greatly reducing magnetic flux leakage and vibration, and adopting an "R-core transformer" that realizes a clean current supply. By installing independent transformers for the analog circuit, digital circuit, and mechanism drive system, a highly pure power supply is supplied. The transformer for the mechanism drive system, which supplies a large amount of power, is stored in a dedicated shield. Mutual interference between each block is minimized.
