I think I understand. But....
Even though they use the term "rated power" in the same category as
Amps/operating voltage used by unit, "rated power" refers to the
actual audio output in watts and how it impacts how many amps drawn?
"Rated power" does NOT mean "operating voltage" ?
:^)
Sorry for such elementary questions. I just found it hard to beleive
that a newer unit would be that much more energy efficient only
drawing 45 Watts.
(though exactly how Sony got that figure. i.e. how loud stereo
playing, is CD motor spinning, I don't know. Kinda like fuel mileage
figures.... YaBaDaYabba.....)
