The presets were introduced as the filtering routines were different
from the actual ones. The idea of that "cd" and "studio" presets
was to get some predefined settings with higher quality and full
frequency response. By the way, you shouldn't take "cd" setting
by word, you will get cd quality only with your original CD waves
(or using some lossless compression routines like Monkey Audio "MAC").
