This is because wav's are not lossy. There is always quality lost when
encoding in to .mp3's and .ogg's, although you might not hear it
depending: (1) on the your ears, (2) the quality of the original and,
(3) the -q level used during encoding. Remember with Vorbis and mp3,
which are lossy codecs, you are always trading quality for file size.
The trick is to find a balance that suits you. Think of them as the
audio versions of jpeg's.

The reason is that you are losing quality twice, first by encoding into
mp3 and then to Vorbis (from losy to losy). This is very different then
encode straight from a wav file.

Hum, last time I checked there are third party programs that does this,
if you don't mind the lost in quality. Try this link:
