*Properly encoded MP3s are *audibly the same *to humans (Destiny)

MP3 isn't a bad encoding scheme in itself, and it needn't make the audio sound any different to humans. All lossy encoding schemes start by throwing away the stuff that no-one can hear anyway. Then packing-up all the redundant data. You start to get audible differences where it is forced into bitrates that are simply too low to represent the content.

Or when you recompress them again, so you can play them on some other device. That's why having your CD as your master is the best.
