The audiophiles would beg to differ since a reverse biased capacitor
is slightly non-linear.

Just take your ohmmeter to an electrolytic cap.
One way you get 10's of megohms, the other polarity, low megs.
Clearly they have different DC resistances since electrochemistry
can still happen at the sub 1 volt level.
