Hi,
I have a PuprePower 2000 power regenerator. It takes the power from the wall and converts the power into a few large batteries, which then powers the components. AC/DC/AC?
Would a regenerator benefit from an upgraded power cord or receptacle, in your opinion? My guess is probably not, but it's totally just a guess.
Thanks,
Mamoru

Follow Ups:
Based upon what others have said, it seems like a good unit. I would give it a good power cord and a good outlet. Not talking big dollar stuff but standard outlets can be 69 cent specials and should always be replaced with better quality outlets (a few bucks each). I have seen many outlets with the wire that just slips into a hole in the back. Think of the wire being grabbed by two small, semi-circular edges that conduct all the current (yuck!). IMO, solid AC power needs to be screwed or, preferably, because it is easier, screw clamped. Note that if it is at the end of serial run of 3 other similarly crappy outlets, it may all be for naught (so replace the whole series with clamped outlets:). Dedicated line, even better.
Look for a power cord with larger gauge conductors.

Thanks.I decided to add another Oyaide R1. I hooked one up to where my power amp plugs in and will add another one where my PP2000 plugs into the wall.
I also opted to get a Pangea AC9 SE MK II with IEC connector to connect the PP2000 to my 15 amp outlet.
I thought about different cables but I recently swapped out my AC9s on the power amps with cables costing 4x more and the differences were prerty slight, which got me into thinking the Pangeas are truly a bang-for-the-buck product. That, and the fact I could get the length I need without scouring the internet for a used one. Plus it arrives tomorrow.
The Oyaide arrives Tuesday. So after Tuesday, I'm done with upgrade/tweaking for a very long time.

Good plan!
If there are any other outlets on the run between your nice stereo outlets and the breaker box, make sure those outlets have decent quality screw clamped wiring. The last outlet in the run will probably have only one set of wiring feeding it. You can track back the wiring run by turning off the breaker and checking which outlets (including those on the opposite side of the wall) are depowered.

Years ago I owned a PurePower 1500. I like what it did for my system.
I tried an experiment. I plugged into the same outlet the PurePower was connected to, a very noisy switching power supply. In the back panel of the Purepower, where all the outlets are, I plugged in my Entech wideband powerline noise analyzer. You could CLEARLY hear, and see the larger number on the digital display.
Moral of the story: These regeneration units do not work exactly the way you think. Cleaner/better power going in, equates to better going out.
No criticism, it is a good experiment but it gets much more complicated from here.
Coupling of RF noise can be conducted or radiated. Without hunting it down, the noise could have gone airborne straight from your noise source to your measuring device since they were physically adjacent. No way to tell what the emission and shielding characteristics of each were in this example. The output of the regenerator could have been clean as a whistle (or not).
Various shielding experiments would have needed to be done to determine the exact path of noise conduction.
Mike
Testing procedure:
1) Noisy switching ps was powered by a true sine wave inverter, which is powered by a 12v battery, and super caps. Totally "off grid".
2) Entech Noise Analyzer placed one foot away from switching ps. Powered from house grid.
3) Entech set at reading of "100".
4) Switching ps energized. No change in Entech reading.
5) Entech moved to six inches away from ps. Noise reading "125".
6) Enteck touching ps. Noise reading of "150".
Based upon the above test, I can conclude that noise does indeed pass from input to output of the PurePower 1500.
That was my experience with the PP1050.When my refrigerator turned on I heard a click through the speakers.
Could not possibly be isolated from other AC sources.

Good experiment.
So you are saying that your original experiment with the regenerator would coordinate with 4 above? Specifically, that the Entech was physically far enough from the noisy SMPS that there would have been no airborne RF noise coupling.
I am surprised that the regenerator did not have incoming low pass filters. Doesn't seem like that would be terribly costly, parts-wise, for such a device.
I use a Topaz isolation transformer and it works really well in my home / system. Output is balanced AC with an independent ground wire to cold water pipe (same as breaker box). I have an additional small iso transformer, with noise filtering, connected to my balanced AC power, that feeds my DVD player. DVD power is completely disconnected if I am spinning vinyl.
Mike
Yes, the original test the switching ps was way more than one foot away.
I also am running "balanced" power, via a single Isoclean PT-3030GII. Better than regen units that I had tried. (PS Audio & PurePower)
Amp is straight to wall. Source is on the above mentioned inverter.
I am very happy with the sound, and that is all that matters.
My 400va Isolation Transformer also providess 'balanced' power and really helps.
Too much is never enough
Mike, I agree with you on this. Good point...
I still have the exact switching power supply. I will devise a test to see if airborne is part of the equation. Will post results here soon.
Wow, good info! That's a wild concept you have checking to see if you have a problem before you try to solve it.
It sucks to get old. It really sucks to get old and bitter.
Thank you for the info.

I have a PS audio PPP. It does a good job. That said, there is an audible effect of different power cords going from the wall to the regenerator.
There *shouldn't* be, but there is.

Thank you.

Looking at the webpage and spec sheet it's difficult to get past the audiophile pseudo science and description. This is nothing more than a hyped up AC inverter. What they don't say is if the sine wave is a modified or pure wave, in fact they seem to do their best to avoid that. I'm going out on limb and saying it's modified due to the omission of detail. If it was a pure sine wave I'm sure the audiophile virtues would be touted in the promotion. An oscilloscope would quickly confirm it.
All that being said I just acquired a Xantrex Freedom 2012 inverter / charger that is pure sine wave with more features than you would need or want for less than $1200 shipped to my home. Along with two Lion Energy UT 1300 LiFePo 105 AH batteries for $1450.

FWIW, our old pal Romy the Cat, did some fairly extensive testing of the same PurePower 2000 unit the OP has connecting it to a scope. In the write up on his site, he found that it indeed does output pure sine. Furthermore, he goes on to state that this is the first, maybe only (since I have not been to his site in some time), re-generator unit he feels comfortable with having his entire system, including amps, plugged in to. The presence of the on-board wet cell batteries act as their own supply storage and for brief periods can supply more current than is available at the wall even.
While I didn't have any interaction with the aforementioned person, at least not directly I was aware of his antics and views. For those reasons I would take his recommendations with a grain of salt.
FWIW the equipment I listed is for an A/C backup with optional solar charging in my RV. This will allow me to stay off grid for several days at a time. The reason I posted it to show with a little homework you could build a better mousetrap. The charge on those batteries would probably power the OP's audio equipment for a week with clean constant voltage.

Wow!Great to hear.
Thank you.

There are no audio devices I'm aware of that are immune to the effects of high-performance power cords and AC outlets in a system, AudioDwebe.
Thanks, Duster.
What I'm having a hard time understanding is if the unit is constantly charging the batteries, and the batteries are outputting the power, do the batteries remember the quality of the electricity charging them and do they then release the clean power?

I don't have the kind of technical knowledge you seek, so I'll just posture this rather ordinary finding. I have a solid state preamplifier with a stiff power supply. When I pull the power cord out of the IEC inlet, the sound continues to play until the power supply caps are discharged. The sonic signature of the preamplifier does not notably change during the time that the power supply caps are discharging, with no power cord at all connected to AC power. The energy storage reservoir capacitors of an audio component is just ordinary anecdotal evidence to ponder; I'm sure other AA Inmates can provide further comments about your particular application.
