<p>WAV --> MP3  lots of loss (at least at typical bitrates, eg, 128)
MP3 --> WAV  no additional loss, but the original loss isn't magically fixed.

WAV --> OGG  loss, not as much as mp3, but irrecoverable loss regardless.

So, the end result is WAV --> MP3 --> WAV --> OGG == OGGs that sound
like ass.  You never get back what you lost converting to MP3, and you
lose a little bit more going to OGG from WAV (the algos are not the
same, and each loses slightly different things).

Similarly, taking a CD, making a cassette recording, recording that
cassette on a computer and then burning a CD will yield something
markedly inferior to the original CD, regardless of whether or not
it's 'digital'.
