Not true.

Without stepping into the essential idiocy of a meter or two of fancy
wiring altering the fundamental quality of power sourced from miles
away through several transforms, switches and many miles of wire...

A shielded mains cable *might* be useful against heavy transients from
equipment nearby, *might* be useful against noise from switching power-
supplies, *might* be useful against local rF sources (and if you
discount this, you have never experienced CB interference from
truckers with massive (and illegal) linear amps on their rigs).
Operative word in all cases is *might*.

I would be quite skeptical. I would pay no more for such a rig. But to
install such a rig purchasing the cable from my local supply-house and
so forth would be no more than a US$20 ordeal including the correct
NEMA plug.
