CEC CD3300R
¥ 47,250 (tax included, released in 2005)
Commentary
CD player with CEC's unique CI (current injection) circuit and LEF (load effect free) circuit.
Instead of the conventional operational amplifier, it is equipped with CI and LEF circuits. This eliminates the need for an NFB loop and enables signal processing in one stage. The fully balanced signal processing circuit enables high-speed and low-distortion transmission.
Pure class A operation is adopted for the circuit structure.
The power supply section uses a toroidal transformer to separate the power supply to the drive section and the D/A converter. The power supply cable is detachable and can be changed according to preference.
The D/A converter uses a Bar-Brown PCM1796 that supports 24bit/192kHz and an advanced segment method that was developed by combining the multi-bit method and the delta-sigma method to obtain excellent dynamic characteristics and significantly improve clock jitter tolerance.
In addition to coaxial and optical digital outputs, AES/EBU is also included.
The analog outputs are equipped with unbalanced and balanced connectors.
It is equipped with a headphone amplifier with a circuit configuration unique to CEC.
There are 2 color variations, black and silver.
