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?

FYI, the Emotiva CMX-2 does DC offset removal for $129 and is a great product. If you have a conditioner you like, you can put the CMX-2 in front of your conditioner and get the benefit of DC removal without having to start over from scratch. 
@sokogear  No, afraid not.  Given the relatively modest price (compared to some others) I just went for maximum treatment/filtration.  Depending on the quality of your incoming electricity, some say the 136 is plenty.

There's a long thread on the 136 over on AudioCircle if you want to read more about it.
Sarjan at 6moons is a big fan of the Puritan line of conditioners and has reviewed both the 156 and the 136 and details the differences. He uses Vibex on his big system and the 156 on his two other systems.

All the best,

Hello,
I just buy once and cry once. The 136 is the lowest I would go in the line.  Later down the road try the Ultimate XX 20 amp power cable to replace the Classic cable which is still an excellent cable. The store I buy from lets you turn in your Puritan Classic power cable for the 15 amp version. I was so impressed I bought two 156 conditioners. That is how good they are. I am waiting for delivery of the XX power cord. One thing:
they need 10-12 days to fully break in. I call it the twelve days of Christmas. On the last day you get the best gift of all. Perfect sound. If you are near the Chicagoland area this store lets you try the Puritan before you buy. https://holmaudio.com/
They also have a new product called the Routemaster coming in a week according to them.  It is a grounding station like other companies have except you can create a new ground for your system utilizing the product called the Ground Master. I have not done this yet but I will before summer is over. I am told you have not listened to this kind of black background.
