CEC CD 2100 - vintage cd player

An audiophile CD player featuring an oscillation circuit known as ‘3RD overtone oscillation’.

In this circuit, the crystal oscillator has been specially tuned to reduce the circuit’s impedance to one-tenth or less of the fundamental wave’s impedance.
Furthermore, it has been engineered to be set to a 1:1 ratio so that the operating ratio can be made more precise with a clock generator; by enhancing the stabilisation of the power supply and voltage, the 3RD overtone wave oscillation mechanism has been improved, resulting in a reduction in jitter. It

is equipped with a Philips TDA1305T D/A converter with zero-crossing distortion. This is a chip that integrates a signal converter and output filter and features a unique combination of bitstream and continuous calibration techniques. The converter functions as a bitstream converter for narrow signals, whilst wide signals are generated using the dynamic continuous calibration technique, resulting in low power consumption, a compact chip size and ease of application.
The TDA1305T is a dual CMOS DAC with an up-sampling filter and noise shaper. The combination of high oversampling up to 16fs, 2nd-order noise shaping and continuous calibration conversion ensures that only a 1st-order analogue post-filter is required.Measures have been taken

to counteract vibration in this unit, such as the use of 4 mm thick extruded aluminium for the front panel, and the addition of a special anti-vibration material to the chassis of the upper casing or the underside of the pickup.

To allow the use of the desired power cable, it is fitted with an IEC connector. The RCA output connectors are gold-plated and of high quality. Thick brushed aluminium

front panel. In perfect working order and in cosmetic condition as shown in the photos.
