how can a line cord affect frequency response ?

gentlemen:

thanks for the repartee. should i give myself credit for engendering animus from the unflappable tvad ?

since i have been communicating (i hope) on audiogon, i am watching less tv. evidently real people are funnier than actors, especially mr g and tvad.

by the way mr t, can i attend your comedy school ? would i have to cross the atlantic to do so, or could we do this on the computer ?

the entertainment i get from reading and answering posts is more gratifying than listening to the "best" stereo system that anyone could assemble.

Twl...Have you ever determined the noise level and output impedance of your battery? It ain't zero! However, if the 12vdc feeds a capacitor, as with a normal power supply, you won't have a problem.

In accordance with Shadorne's observations about coal-fired power plants, have you noticed any difference in your sound depending on whether the solar panels were exposed to bright sunlight or only a dingy overcast?

to post, i must, for my cause is just
and this is my motto, "in words do i trust"

some say i stir things up, like an unruly pup,
puckish, picaresque, iconoclastic and a bit rebellious too ?

nobody is perfect, we all have faults
i give it and take it, so keep your cool and heed this rule:

life is too short to growl and snort over a mere bagatelle of audio opinion

tvad, i hpe i have saved you a trip to your therapist, you certainly have let off steam.

i hope you feel better.

Regarding the question how it is possible that a power cord can affect frequency respose: can it be measured that one power cord gives a slightly different frequency response than the other? Even small differences (+/- 0.5 dB) could be heard. If the differences are less than 0.5 dB then you can say that there are no measurable differences between power cords and that that sonic differences between power cords (if there are any) should not be heard.
