You are right I just checked with different headphones, and I don't  
hear it with those -- only my sony mdr-7506 do reproduce the  
artefact, and trust me, with them it does not sound like a -60dB  
noise ! (those headphones are very very sensitive to high frequencies)

For people who may want to check if they hear the difference, I have  
put two wav files here
http://gruntthepeon.free.fr/test/m.wav
and
http://gruntthepeon.free.fr/test/m2.wav

they were obtained from the same mp3 file with a "default" and a  
"64bit" version of mpg321
