capacitor dielectric bias

I've seen speaker cables with dielectric bias.
Why not capacitors, too? It'd be like biasing a transistor to reduce switching noise.
is this wacky?
If it's possible I want a a piece of the action, after all it was MY idea!

Here's a pic of the 5A crossover with its 27V. stack of 9-Volts. http://i89.photobucket.com/albums/k220/jeffreybehr/0%20Vandersteen%205as/Boardtop1_1280w.jpg .

If not biased, they will distort. This has led to a bad reputation for electrolytics, one not deserved if they are actually treated properly.
