Anyone else regenerating A/C?

I'd like to second an earlier post asking for a listening omparison between the Shunyata Hydra and the Exact Power EP/SP combo. Has any one auditioned both?

It doesn't appear that the two power solutions compare like apples to apples. The Shunyata webpage says that the Hydra filters noise and isolates the components from each other, but does not claim that the unit regulates voltage.

Shunyata doesn't say how the Hydra's component isolation is accomplished, but apparently it does not offer a dedicated iso transformer for each outlet, as with the PS Audio Power Plant Premier. From the ExactPower webpage, the EP15a only separates the digital outlets from the rest. Can anyone make the case for the further isolation of EVERY component from every other component, via separate iso transformers or other filtering methods; or should it be sufficient to isolate the digital gear only?

A more recent technology comparison would be the New PS Audio Power Plant Premier vs. the New Shunyata Hydra V-Ray. These are both new and updated technologies which should bring power conditioning to a new level. I also heard Furman has recently released some really good conditioners as well. I’m interested to hear anyone’s experiences with any of these fine products.

Ubglub: Neither the P3 nor the EP15A use iso-trannies for outlet/component isolation. The P3 has more (and, it would appear, more extensively) isolated outlets than does the 15A when used by itself, but both units use filters for that purpose, not iso-trannies. The Shunyatas, in common with most PLCs, are passive units that aren't transformer-based, so they can't regulate voltage or provide balanced AC (of course Shunyata would argue for the superiority of their approach based on other reasons).

The API Power Wedge Ultra 116 I use after my EP15A has six individual iso-trannies for source components and preamp, each individually selectable for balanced, floating, or regular operation. In my system balanced is almost always best sonically (but never worse) for each attached device as compared with the other settings, so I believe I can vouch for the general efficacy of balanced AC (which the P3 provides by itself). But there's no meaningful way I can make a comparison of whether the individualized level of inter-component isolation I'm getting is more beneficial than a lesser degree of isolation would be, without also introducing uncontrolled variables which would invalidate the test, though one assumes it couldn't hurt as such -- the possible exception being if the iso-trannies were in and of themselves inferior-sounding to another, filter-based approach (something I can't answer, other than to say that using the PWU results in better sound than just plugging my sources straight into the EP along with my power amp, *even if* balanced AC isn't selected on the PWU).

I have read this thread with great interest. I have an aging EP15A and have been considering the PPP for the reasons people discuss here (more outlets, better isolation) and a few other reasons not mentioned so far (has surge/spike protection for satellite/cable connections and for telephone, also has multiwave). Can anyone tell me how the SOUND compared when powering their system with an EP15A and with the Power Plant Premier?

thanks!

Hi I m currently using a EP15A. Anybody change to stock power cord? if yes, what do u like abt the changes brought abt by the new PC? Happy listening
