[vorbis] quality question?

Transcoding ALWAYS results in a loss of quality, since the codec will try to 
encode any artifacts from the previous encode, being unable to distinguish it 
from "real" sound data. Peeling peels away data and should not result in a 
quality loss, but this is not yet finished.

You can listen to it and see if it sounds satisfactory (q 9 is quite high), 
but it will be lower quality than from wav -> q7. If you have the audio 
source, it is probably not much harder to encode from that to ogg, in fact I 
think it might be easier....
