I have gotten perfect MP3s from lame with the following:

lame --vbr-new -B 320 /home/jjj/cdda.wav /home/jjj/happyfunfile.mp3

Where cdda.wav is the file created by cdparanoia and happyfunfile is
the name I want to give to the MP3. Note that the above command will
use 320 kbps if needed to preserve quality, but otherwise will drop to
whatever preserves the same quality. The resulting MP3 is perfect with
no loss of quality, but is much smaller than an MP3 encoded completely
at 320 kbps. For symphonies and operas I find that it averages about
200 kbps, although occasionally I see it bump up to as much 280.
