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

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.

I decided to give the Audiophile APS 1050 a try. I'll you know how it goes when I get it in a few weeks.

Yoryios -- I forgot to answer your question about wire sizes. You are correct, most codes only require 12 AWG for 20A circuits. Sometimes you do find 10AWG in 20A circuits, especially in better construction and/or where there are long (over 30 feet) circuit runs, because of the voltage drop that starts usually around 20+ feet.

I always recommend that for dedicated audio circuits, if your runs are going to be over thirty or so feet, that you install 8AWG wire. Tip: ordinary duplex outlets will not accept 8AWG wire. Make sure to get outlets with "gas-tight" connectors so you don't run into problems. Gas tight connectors are basically clamps, where you insert the wire into a clamping mechanism which is then tigntened with a screw. Most hospital grade 20A outlets are of this type.

I received my Audiophile APS 1050 a few days ago. Well, WOW!!!
The addition of this unit to my system has made a more significant improvement to the sound of my system than almost anything I have done to my system in recent memory. I am now a true believer in power regeneration. I must have had some really weak power delivery in my home. I would recommend people try such a devise before making any other major component changes. WOW!!!

Everything in the sound of my system is qualitatively and quantitatively better. Total Engagement!!!
