Okay, let's start at the start and take it in baby steps.

Thank you for the explanation...

Inside the house,
half the "110" outlets are off one hot wire and the others are off the
other one. You could find two outlets in the same room and if they were
off different hot wires, run a wire off each one and get 220.

But they have to intentionally run both hot leads to any outlet that needs
220?

For the last forty or so years, most every piece of electronic
equipment designed to be interfaced with other electronics has had such
a power supply.

I didn't know that.

So when it was discovered that running power with two
hot lines equally spaced from ground-balanced power- had big advantages
from noise and EMI standpoints

I didn't know that either.

If your hi-fi amp has a linear power supply designed for multivoltage
use, you ought to be able to run off the 220V "air conditioner outlet".

So you are suggesting we do, either by switching the switch, or by opening
the box if necessary?

If a house is
wired from pole pig to fuse box to power outlet with regular old wire,
how is a relatively short length of high dollar wire going to make a
difference?

I've never really believed it could.
