Well, it doesn't reproduce them. It invents them.

I've played with DFX (and similar plugins like Wow! Thing) and have yet to
find settings that make my MP3s - I don't do much downloading - sound
better. They're fun to play with, but tiring on extended listening.
If the MP3s are "borderline" - i.e. only barely transparent - such
processing can make things much worse, by revealing distortion that would
normally be inaudible. To avoid that you would need to use a higher
bitrate, i.e. pick a bitrate which is transparent, then use a bitrate (say)
20kbit/s higher than that.
