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?

@millercarbon - I have one - a Furman elite 15i, which is a little above entry level and was thinking about upgrading to one that did more than filter. When I originally got it, it was for functionality of having a large number of outlets and protection against power spikes, but I found it improved the sound a little.

For a very cosmetic reason (other boxes are silver, Furman is dark brown) I am considering a change. I like the fact that the Furman shuts off when it senses a problem and has a switch on the front, that I haven't seen on some.

There are so many out there, it is really unbeleivable.

PS Audio's line is famous for doing just that.  PerfectPower was somewhere in between, storing enough energy to correct the waveform without necessarily being able to recreate missing waves.

I wrote quite a bit here:

@erik_squires - sounds like you are a fan of my Furman.....good to know. Now if I can only get a silver face plate for it......any ideas?

Capacitors have values, the unit of capacitance being the Henry. Most of our caps are measured in mH, milli-Henry’s, because it is a hard way to store energy. 

Uh....No. The unit of capacitance is the farad. The unit of inductance is the Henry.

What you are referring to is called a "power supply smoothing capacitor" and every amplifier already has one (or more) in it :-)  You do not need a power conditioner for that function :-)
