(I've never used the Sony 300 disc player), and I've found it quite suitable for playing soft background music at parties we've hosted, even with the constant CD shuffling that random play requires

The unit provide safe storage as well as hours of great music always at you finger tip

It has a much smoother changing mechanism, controls are logical, and the music sounds excellent

It plays flawlessly with the most intricate music.

I can play all my free, downloaded music on this box
