Once an MP3 is made, the loss in sound quality is permanent. No way to
restore it.

That said, most of the time for most listeners, even a 192 kbps MP3
will be indistinguishable from a CD. So you haven't lost as much as
you think you have.

Also, don't read DAC reviews. They're essentially creative writing
exercises.
