Commentary
A CD player with advanced high-precision master clock technology.
An advanced high precision master clock is used as the master clock.
This oscillation circuit uses a discrete circuit to obtain a high-purity clock signal. This circuit is based on a Source Follower circuit and has a characteristic of gain less than 1, so it oscillates an accurate reference signal without amplifying external noise.
The DA converter employs a 4th-order 0 shift noise shaping 1-bit D/A converter in order to improve the SN ratio in the audio band.
The phase and high-frequency characteristics are improved by pushing the requantization noise out of the audio band and cutting the high-frequency noise.
Digital servos, OEIC pickups with built-in RF amplifier circuits in the pickups and digital attenuators are used.
Wireless remote control is included.
