Power conditioning v re-generation; Shunyata v. PS

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.

Everyone - thanks ! As many have pointed out - there are no answers ! It's hard of course to compare units side by side. Maybe I will buy a Shunyata and try though, and then sell the unit that is not as good. Thanks again !
