i did actual hearing blind-tests with 4 people that title themself 
"audiophile", on their hardware THEY tell have excellent sound output (actually it was 
really good for me).

results

lame -h -V 3 - nobody could tell the difference, it gives <200kbps bitrate
lame -h -b 192 - as above
lame -h -b 128 - they were able to tell difference, but not on all 
music/songs

lame -h -b 96 - i was able to tell the difference on every song, but it 
wasn't really huge deal.
