Power conditioning v re-generation; Shunyata v. PS

Wouldn't the effect of any power conditioner, including these, depend upon the mix of components in your system?

Magfan, yes Powerplants are essentially amplifiers generating 60hz. Markny, It does not output power from a battery. Ncarv, yes, the perceived benefit of regeneration vs. conditioning depends on your equipment and tastes. I've seldom seen a product category that generates such diversity of opinion as this one. Anyone who thinks they are going to get a definitive thumbs up or down on this question is going to end up more confused than enlightened after the forum dust settles. For instance, Jeff Dorgay, the publisher of Tone Audio magazine, can't stand any of the Powerplant regenerators. He's listened to many of them and dislikes every one. (Read his recent posts about this at Audiocircle if interested.) As mentioned earlier, he thinks they suck the life out of the music. However, for every detractor, there are plenty more who love the regeneration route. I've been reading reviews and posts about this product category for many years, and every single product has it's detractors and enthusiasts. You'll just have to try for yourself.

Markny said "If the PS unit is producing new power from its battery - why do they recommend that I upgrade the power cord from the wall to the unit ? It would seem to not matter what is going in since it is totally re-created as new power from the battery. Any explanations on this one ?"

Assuming that the power cord from the wall to the unit is rated for the current requirements, there is no robust technical explanation for replacing the power cord. If the company recommending the power cord upgrade is also selling power cords, then the explanation is that it will benefit the seller if you buy a power cord from them.

Markny, all that being said . Upgrading the power cord from the wall to power conditioners usually improves the conditioner output. The PS which I had owned is nothing more than a power conditioner with a differnt approach to the method of power conditioning.

Example: Of improvements .
I have a Hydra 8 that I use for my Video only.
When I began using a Virtual Dynamics Revelation 2.0 power cord into the Hydra 8 the video improved greatly.
Whats that phase we all like to use," garbage in garbage out".
In other words, give the conditioner the best possible AC to work with .

But, I personally run my Audio (CD,Preamp and Power Amp) directly from 3 dedicated circuits with power cords that complement the quality of each component. I find that though the Hydra 8 and other Conditioners clean up the sound a little , running direct into dedicated circuits has more dynamics.

Musicnoise: I'd say it's because the PS power plants are not perfect.
