Anyone getting good results with speex?

I just found and used dbpoweramp and converted some mp3s to speex. Not
been satisfied with the results at all though I used VBR and the
largest filesize I could tolerate already nearly equalled into the
smallest vorbis I could get in size but far from its quality.

Any ideas?

Speex is good for recorded speeches, not for music.
So let's assume you have a speech in pure .wav format. If you encode it
with mp3 and speex, you will get much better results with speex. But
what you try to do is called cross-coding, which is a bad thing. There
is no way to get good quality by re-encoding something that had been
encoded ito another format before. Never.

Yes, they are speech in nature. You see, the thing is, I'm getting
very, very good results when cross-coding from mp3 to ogg. The filesize
is the fraction of that of mp3, and yet the quality, when I listen to
them one after the other, is hardly any different, eventhough I'm
encoding at 0 quality ogg vorbis. Not so for speex; when cross-coding
from mp3 to speex, and experimenting with the settings, even when the
file size approaches that of the ogg vorbis sample, it's still
remarkably bad. :-/
