This long-awaited CD transport in the Reference 500 Series employs a CD drive with a new design based on specifications TEAC uses for professional products. With support for 10MHz clock input, not only can this transport be used together with a TEAC Reference 500 Series DAC, it can also be used flexibly to enable high-quality audio CD playback with a variety of digital playback systems.


  • New drive control circuit maintains a natural rotating state
  • Discrete power circuits use toroidal core transformers
  • Crystal-oscillator-based internal clock with low-phase noise used
  • Full-metal enclosure increases vibration resistance
  • Stressless Foot, a TEAC original design with three support points

Dedicated CD Drive Design Improves on the Drive Developed For The TEAC CD-5020A

The CD-5020A is a TEAC original drive that they proud to have developed. This his has been used for broadcast applications because of its durability and reliability. Based on the CD drive design used in the CD-5020A, TEAC developed a new design optimized for the PD-505T.

Semi-Floating Mounting

The entire CD mechanism is mounted in a semi-floating state that is not completely fixed to the chassis of the unit. This design, developed with meticulous care, prevents feedback that can have a negative impact on CD reading by preventing the transmission of vibrations generated by the spindle motor and actuator to the chassis and causing sympathetic vibrations. At the same time, in order to eliminate impact on the audio quality from dampers used when mounting drive components, TEAC also designed locations where they employed rigid attachment methods. By doing so, TEAC has realized CD reading that is more accurate and maintains a higher level of purity.

Drive Control Circuit with A New Design

Seeking an even higher level, TEAC designed a new drive control circuit for the CD mechanism. By controlling the spindle motor with gentle feedback to create a natural rotating state, they realized an even more unaffected and open sound. Furthermore, BTL drive, which does not generate switching noise, is utilized, starting with the spindle, and also including the actuator that drives the pickup lens. This eliminates minute impacts on signal reading and increases the purity of the signal.

Discrete Power Circuits

Toroidal core transformers are used for power supplies. Furthermore, power supplies are separated for the OLED display, the CD drive and microcomputer circuit, and the audio circuit, with dedicated secondary coils and rectifiers for each. In consideration of the audio quality, independent discrete power circuits are used for the CD drive, the microcomputer, and the audio circuit.

Crystal-Oscillator-Based Internal Clock with Low-Phase Noise

With digital connections, the clock precision of upstream devices can affect the quality of the entire system. A low-phase-noise crystal oscillator, which has outstanding phase noise characteristics, is used for the internal clock of the PD-505T. By reading CD signals based on a high-precision standard clock, the original sound stored on the CD can be accurately output digitally.

10MHz External Clock Input

The sound can be enhanced further by inputting an even higher precision clock signal from an external source. Moreover, in a digital playback system, not only can audio quality be enhanced by increased upstream precision, building an even higher-level digital system becomes possible through, for example, clock synchronization with a DAC.

All-Metal Enclosure with Vibration Resistance and A Stylish Appearance

Since the entire body is constructed from metal panels that are resistant to external noise, intrusion of electromagnetic noise generated by computers and other devices is suppressed. This achieves a clean internal environment with little noise even in conditions that are difficult for audio equipment. Furthermore, the 8mm-thick aluminum panels, which cover both sides of the all-metal chassis, provide an installation structure that does not unnecessarily twist or bend the chassis or front and back panels, realizing a strong and precise form. Moreover, with the size of an A4 page (viewed from above), the unit can be placed on a desk, side table or other small space.

Original Stressless Foot with Three Support Points

TEAC’s newly-developed original Stressless Foot design with three support points enables stable placement so that it is not impacted by slight irregularities in the surface beneath it. Compared to those used in previous designs, these feet are only partially fixed to the chassis. This design was developed based on the concept that by allowing the feet to vibrate freely, more natural sound reverberations could be achieved. Rather than being attached firmly, these machined steel feet are installed so they are loosely connected to the bottom of the unit. While maintaining a sense of placement like that of the pin-point spiked feet used by previous models, this design enables more natural rich reverberations.

Semi-Floating Top Panel

A semi-floating top panel design is utilized. The top panel is not tightened to the chassis with screws. Instead, it is partially fixed, secured only by the side panels, realizing a sound instilled with an open feeling.
