This CD transport in the Reference 500 series uses a newly designed CD unit based on specifications used by TEAC for professional products. The CD-5020A is an original unit by TEAC, designed for professional applications due to its durability and reliability.

Semi-floating mount: The entire CD mechanism is mounted in a semi-floating position, preventing feedback that could affect CD reading. The new design ensures that CD reading is more accurate and maintains a higher level of purity.

Motional transmission control circuit: A new control circuit has been designed for the CD mechanism, which reduces noise and ensures a cleaner signal.

Discrete power circuits: The power supplies use toroidal core transformers and are separated for the OLED display, the CD unit, and the audio circuit, ensuring sound quality.

Internal clock with crystal oscillator: A low-noise crystal oscillator is used for the PD-505T's internal clock for accurate CD signal reading.

10 MHz external clock input: The input of a more accurate clock signal can further improve sound quality.

Hardware design: The fully metal casing offers resistance to vibration and an elegant appearance. The entire body is made from metal panels that are resistant to external noise, ensuring a clean internal environment.
