"...nobody can hear the difference between a 320kbps CBR audio file and the CD."
"Set B was the MP3, yet for those who picked A or B, most thought A sounded inferior!"

"The results of experiments conducted in this study showed that, in all listening conditions, music samples compressed by lossy compression codecs proved undistinguishable from original uncompressed samples for bit rates of approx. 96–128 kbps."
"Differences in files at 128 kbit/s and higher cannot be noticed within the majority of listeners"
