I heard about this on a radio talk show. I think they even wanted to put the
notch on vinal (sp?) records. There was an experiment done wherein listeners
could play various selections of music with and without the notch (not knowing
which was which) and then attempt to say which had the notch (like "Coke" or
"Pepsi"? :-).  Anyway, one piece had a picollo solo completely drop notes
because they were just at the right frequency. I think the experiment was
run by the Senate in some sense because the recording industry was trying to
get a law passed that would require DAT manufacturers to put in the notch-
detection circutry.  I don't think it was "magic" that made the issue 
disappear, but rather the fact that audiophiles could detect the differences.
Heck, I could hear the differences over the radio driving home from work in
traffic!
