I had this one! So many features, for such a lowly sound quality! And the worst thing is that even when you turn ESP2 (which means compression) OFF, in Sony models that I had tested, it was still ON! So, the sound is always as "good" as you would expect from a decent MP3 file. I love Discmans, but they were responsible for what we have now: most folks do Not hear the difference between hi-end analog and compressed digital, and such folks nowadays rule the Earth
