RLC doesn't affect DC... but power cables handle AC
My point was that what minimal effect the cable properties have on the 120VAC signal will be pretty much gone by the time you've been through AC-DC conversion and passed through the active components. And the effect will be much less than normal psychological and physiological variability.
