Well, let's not get carried away here. Impedance matching isn't an issue
in _most_ audio amp/speaker circuits (the great majority of output stages
approximate a very low impedance voltage source at relevant audio
frequencies, and speakers are almost never constant impedance over the
audio bandwidth anyway). I guess if you had really long lines...
This is so far off-topic I probably shouldn't have said anything in the
first place. I'll stop now.
