Power conditioner types


Do any power conditioners actually store the energy from the outlet/power company and then generate it on demand or do they all filter the current as it is coming through?

Or is it more complicated than that?

If any do store it, are they a different class?

Good correction:
Farads, millifarads, microfarads. 
A Farad is quite a large amount of energy storage capacity. For example, my current power amp has 108,000 uF, or 108 Farads. A lot of storage and smoothing for a D.C. power supply.

I think this is called a battery. but then you would also need an inverter to transform the DC current back into AC if you want to plug-in big stuff like amplifiers. better yet, you can run some components like dacs directly from the DC current and completely isolate them from the grid without too much battery power. Anything that runs off a wall wart take power supply is a candidate for a DC power from the battery.

A can of silver spray paint should do the job. :-)
Knowing very little regarding 
power conditioners...
they improve sound but do they protect equipment should
a power surge occur or are they 
possibly damaged as well?
Appreciate your input regarding
