Power Filtering vs Power Regeneration?

I use a P3 for all of my source components. Clean, stable and low distorted power. Pure Power is another option but have had no personal experience with them.

I have the PSAUdio P10 and it works great. the latest firmware was a great up grade. talk to PSAUDIO they will help.
good luck Pete

I allways used passive filters. First the old Lessloss and now the Bybee Holographic. They really made my system better
I have power full tubed mono amps and only passive can drive all my system without losses indynamic, but I'm far from having listenned every power regenerator.
Now I'm watching in the grounding filtering direction with some Entreq products like Silver Tellus and Atlantis

Halcro,
Have you actually documented what's going on at the wall socket during those periods where the sound deteriorates? It would first be prudent to do that, so you are not wasting money on a (expensive) power regenerator. Another reason to do that is to determine the magnitude of the AC voltage swings, if indeed that is the cause of your problem. Because different regenerators will have different capacity to maintain constant AC output for a given variation in input AC. Two excellent brands of regenerator: PS Audio and Furman.

It's also possible that someone in your neighborhood who shares your AC or some household appliance is switching in and out, causing disturbance on your AC line, when switched in. In that case, of course, you need some sort of filter or dedicated AC lines, or both, and not necessarily a regenerator.

Halcro,
Look at this product:

Quite a few have upgraded from really good power regenerators to this passive product in my city. I personally use the lower end model called 6GG and it is just terrific. Music is so pristine, detailed and extended, it is a revelation.

If you must use a regenerator then look at APS Purepower
