If I remember correctly, the way was to use sound-juicer and the default AAC
pipeline 

audio/x-raw-int,rate=44100,channels=2 ! faac ! ffmux_mp4

for ripping and then play back using any gstreamer app.

YAP, I can still reproduce also with the pipeline

audio/x-raw-int,rate=44100,channels=2 ! faac outputformat=1

the results sound identical to me - there are two problems I can hear:

1. I suspect the replay gain is not working fine. For instance on medium and
strong acustic guitar strokes the subjective volume drops significantly and
then increases again afterwards. That explanation is just  guess.
2. there are tiny (mute) gaps when playing ocurring occasionally. You can hear
it best when there is a tone of constant frequency sounding for some time. It
is not easy to notice.
