ExactPower EP15A

I was thinking of getting one of these after my not so stellar audition of the PS Audio P-500. Guys that have or have had one of these (the latest model)good or bad stories about them? Do you have everything plugged in to it or just front end gear? Break in time? Different power cords? I've heard that Ps Audio tried to buy the patent from ExactPower but they weren't going for it. It EP15A looks a better design all the way around. I was thinking of the World Power Power Wing but it doesn't do anything as far as maintaining voltage from a low or high voltage situation or correcting your 60 hertz signwave. The EP15A will maintain 120 volts at it's output while the incoming voltage drops as much as 86 volts, upon hitting 85 volts the unit shuts down to protect your gear also keeps you a 120 output up to 139 volts and shuts down at 140 volts, doing all this with minamal heat unlike the PS Audio P-500 that was spontanious combustion hot with just a 12% 52 watt load on it. Thanks

Pardales,
in not only my experinece the rgenerator gave by far the more important improvement than the balanced power, as I have described above. However, balanced gave another improvement. There are units that do both, as the PS Audio and Burmester, but from I learned when doing my research, the Exact Power combo was cheaper and better. Maybe you can get a unit or even both, for home auditioning first.

PS Audio offers a 30 day trial on their products. Worth a try based on this.

Pardales, please go back and read the first three posts on this thread -- should answer most of your questions. I (sort of) agree w/ Hassel. The only time you would do a balanced power unit first, would be if you had dedicated AC circuits and pretty reliable (constant voltage and accurate 60 cycle) from your power company (like if you live near a hospital or other major facility) and then you could do balanced power just on your front end stuff.

Nsgarch: Thank you. Going back and reading the first few posts of this thread was clarifying. Conclusion: clean and stable power, then balanced power.

One other question: could I stack an SP15-A and EP15-A on top of one another or would there be to much heat? I only have one shelf left on my rack.

Also, what about the Equitech "Q" units? Is there such a thing as a unit that cleans, stabilizes, and balances.

Thanks,

As far as heat is concerned, you could stack a EP over an SP with no problem. The SP has no vents and doesn't even get warm. The EP is minimally warm.

I don't know what the electronic interaction might be though. You should check with Brent Jackson at Exactpower.

All the BP units have line filtering and overload protection. The Exactpower also has surge protection, but I don't know about the other two.
