From Sony's product page:
Equipped with ATRAC / ATRAC3 DSP TYPE-S that further improves the playback sound quality in MDLP mode. It is now possible to reproduce even minute sounds that were previously truncated, reducing noise by approximately 6 dB compared to our conventional model. The effect is also exhibited when playing on a portable MD player.
In addition, the dynamic range of the core DSP for ATRAC and the audio data of peripheral circuits such as digital in / out have been increased from 16 bits of the MD standard to more bits.
We have also introduced wide bitstream technology for recording and playback with a wide dynamic range. Since there is a margin in the number of bits, more faithful recording / playback is possible with the original sound. In addition, it is equipped with an SF edit function [*] that allows you to readjust the level later even if the recording level is uneven due to differences in the input source.
You can also fade out a song that has been cut off in the middle, or start with an impressive fade-in. MDS-JE580 pursues quality as an audio component. It can be used as a center deck for MDs that are widely used.
