Can anyone point out a commercially available microphone used in the 
audio recording domain which will actually pic frequencies above 20 kHz?

Likewise can anyone point out any commercially available speaker used in 
the audio reproduction domain which will actually reproduce frequencies 
above 20 kHz?

If the audio produced is made for fruition of humans it makes absolutely 
no sense to try and capture or reproduce anything above 20kHz, and for 
average individuals 15kHz would probably more than enough.

And in case anyone is tempted to state that even if we don't hear them 
frequencies above 20kHz influence the way we hear or 'perceive' music, 
please also attach any _scientific_ study/paper/evidence (e.g. 
large-scale blind tests etc. not anecdotal evidence) to such statement.
