TEAC PD-505T
The PD-505T CD transport is a long awaited addition to the Reference 500 series. With a dedicated CD drive based on the renowned CD-5020A, PD-505 delivers an accurate CD reading with a high level of purity. The semi-floating mounting and new drive control circuit enhance sound quality, while discrete power circuits and low-phase-noise crystal-oscillator-based internal clock elevate performance.
Its all-metal enclosure and Stressless Foot design ensure vibration resistance and stylish aesthetics. With support for 10MHz clock input, not only can this transport be used together with a TEAC Reference 500 Series DAC, but it can also be used flexibly to enable high-quality audio CD playback with a variety of digital playback systems.
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, we also designed locations where we employed rigid attachment methods, for example, and considered overall vibration modes in making a structure that employs both rigid and flexible aspects. By doing so, we have 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, we designed a new drive control circuit for the CD mechanism. By controlling the spindle motor with gentle feedback to create a natural rotating state, we have 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 use toroidal core transformers
Toroidal core transformers are used for the 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 used
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.
