Thomas Stockham (of Soundstream fame) explained that this was pulsed
noise, fuzz that accompanies the recording superimposed on each note. 
We get used to it and miss it when it is filtered out because it is not
really part of what went into the recording.  A way to trick our ears
into believing that the top end has not been filtered is to return a
slight amount of surface noise in the 12-14 KHz range.
