Features :

* The design of the device begins with the SANYO cassette mechanism ensuring high stability of playback of each CD. The laser servo is a construction of the PHILIPS SAA7824 company, while the DAC decoder uses the American BB Corporation PCM1794U chipset. 

* The DAC also has a built-in multi-layer digital filter, and the signal amplifier path uses two 6H8C low-impedance tubes. 

* The output transformer of the audio track has a Japanese core construction (sheet thickness 0.35 mm) and pure copper wire with high-strength insulating email. A special transformer winding process allows for a wide frequency response to ensure clear and strong sound across the entire scale.

* The SD-38A player is also equipped with a coaxial digital signal output which can be connected to an external DAC decoder.
