Sorry if my original article wasn't clear.  I was suggesting using 75 ohm
coax between the preamp and the amp (which is located at the speaker),
NOT as cabling between the amp and the speaker - the latter is clearly
silly.  The idea of using properly-terminated 75 ohm cable driven by
a 75 ohm source at the preamp was to get around the problems due to
sending the signal from the preamp to the amp on high-impedance coax.
This would solve cable capacitance problems, wouldn't it, as well as
hum pickup problems?  (I'm not an EE, so I don't have enough knowledge
to tell if there are holes in this argument.)
