Thanks for the note UTGG. I've heard a similar comment with psychoacoustic encoding as well. I remember running into an older fellow (mid 60's) with sensorineural hearing loss from acoustic trauma a number of years back who claims he could hear the difference in MP3 even at high bitrates. He attributed it to his own hearing damage such that the normal mechanisms of auditory masking didn't "work" for him any more. Good insight I thought in that he didn't just proclaim that "MP3 sucks!", but rather realized that he could hear things that were "different" when his own kids and grandkids had no complaints.
