Take somebody that just bought one of those cables outside his house,
point up at the power line coming to his house, then whip out an AM
portable, scan down the spectrum, and let him know that *all of that*
was hitting his socket, and being transmitted with extreme fidelity
across his $550 power cable to his power supply.
That's the face I'd like to see.

FWIW, I tend to use computer power cords ($1 per) for all my stereo
equipment.

No. For one thing, a thin cable is probably doing more filtering than
a thick one. And the power supply is heavily regulated in any case,
which is why the dirt coming in from the power company doesn't come
out the speakers.
It's 100% pure snake oil.

I suspect the the power supplies have the most snake oil. 90% of all
the power supplies
I have seen looking for a good valve amp schematic have heavy filtering
but very little regulation.
My 115 volt ac is about 123 volts out here.

That doesn't make the power supplies snake oily. Tubes are generally
not picky about the supply voltage, so no regulation is needed for
good performance. There are a few exceptions: precision oscillators,
and traveling wave tubes. But your basic tetrode or pentode amp is
quite uncritical; regulators would just be unnecessary bulk.

Hmm, how about battery power? I wonder why those audio
guys just don't use a gang of car batteries to power
their stereo. Can't get any cleaner then that.

But then he would show you his power line conditioner and separate cleaner
that is removing all that interference...
