I am currently using 192 since it is supposed to be better than CD Quality (120 bitrate).
Sorry but that is untrue. Not that CD quality is perfect, but when you use any lossy encoder to compress the music (such as MP3, AAC, Ogg, etc), you lose quality no matter what bitrate you use. The lower the bitrate, the more you lose. Thus, it's impossible to be "better than CD quality". At high bitrates, the compressed quality can be very good or perhaps even undistinguishable from the original, but never "better".
