I'm confused as to the importance of impedance matching...  Since I may
not know the whole scope of this subject, I'll say I'm referring to things
like stereo line-level, headphone, microphone, antenna inputs and outputs.
I can see that if you have a high impedance source, you need to have a high
impedence load or input so as not to load down the source.  So what is the
need, when you have a low impedence source, to have a low impedence load?
