We have a winner ! even a really good MP3 will drop off rapidly after 19K or 20K, in theory with LAME 3.92 you can set the low pass to 22.05 but whenever I have tried this it will still truncate high frequencies abnormally while a wav file will slope off more gradually.

In later versions of LAME the ability to set really high low pass filters has been more or less disabled.
