Max, it sounds like this is not a case of ground (loop) hum, although 3V might well cause problems with HE speakers, depending on how the system grounding is stacked. As a control, try running the APS off its battery while it's loaded (ie, the amp i...

[quote user="Romy the Cat"].[/quote]What do you know, today is December, that makes me to use the APS Purepower 2000 for one year. I would like to share some observations about the experiences.Since I posted my comments last year a few folks I know b...

OK, at this point I might say my patience with APS has paid off and this new 2000W unit is something way more civilized – a very cool New Year gift to me. The result that the regenerator produces is VERY interning and I think it would be worth to tal...

Above, talking about APS-like regenerators, I was skeptically referred to the battery back up functionality in the APS PurePower, calling it bogus and completely unnecessary. It was very funny to read at the APS site as the APS guys promote their uni...

I did not say how my saga with APS Pure Power regenerator finish but it never finished. Since the end of the last year the regenerators is sitting in my closet and I have sent the unit’s main board to APS people for the “revision” as I do not feel it...

Petrasescu_Lucian,
I perfectly understand your sentiments. There are unquestionable differences in operation between 1050 and 2000 but I do not know if it is the differences due to the topological differences or due to implantation differences...

Guys,
you do not need to ask this question to anybody else but the APS themselves. Would it make sense to ask a manufactures about the principles of their products operation?
I would certainly not talk to the APS re-salers as they even fur...

[quote user="Antonio J."] I really can't understand how a company selling a power regeneration device priced well over 2000 or maybe 3000 USD could send you 5 units and being al them "defective". Did I miss anything here? [/quote]
Nope, you do not m...

Well, dealing with Purepower I think it worth to understand the APS specific. They did not impress me as an engendering shop but rather they are the long-ceremony type of operation. It is not that you comment on some kind of problem on the fi...

[quote user="Paul S"] I think you mostly get where I'm coming from and you just don't like it, and your criticism is smart, and your points are well taken; but there are a few things going on here that just bug me that you either seem oddly comfo...

Thanks for the update, Bill. Good for you! It would be so great, after all these years, to finally be able to take electricity for granted...Meanwhile, perhaps I am not the only one hanging back, watching the failure rate and APS responses from a saf...

Yep, guys, thanks, I hear what you saying and it is true - the possibilities of the power devises in commercial and industrial world are endless. Even among regulators there are dozens and dozens companies that DC-AC inverters. Some of them might be ...

Yes, it is pisser but it looks so far that APS is failing at much more prosaic and much more “earthy” level. I do not know if they would go for a “better” PurePower regenerator as it looks like they sell fine whatever they are selling. I ma sur...

Well, my ride over the APS PurePower wave did not finish yet. As this point I am convinced that my PurePower unit #5 is also defective. I have a conversation with PurePower people and they will look into it. I still fill that my unit #1 and my curren...

[quote user="Romy the Cat"]... I will showily dump in this thread some observations of mine about APS PurePower regenerator... [/quote]If you, I, they, we, whoever… consider APS PurePower as just a power treating or regenerating devise then I feel th...

Romy, this whole report is just too interesting to wait for installments! I love it that you have found a way to "work with" the "effects" of the APS. But now I wonder about and I hope you will clearly address:Whether you use all com...

[quote user="Antonio J."] … looking like the Kemp's unit. But that's provided the input electricity is still under 5% of distortion. They also state that that performance is under linear load, so it might be possible that using chokes or trannies loa...

[quote user="Paul S"]Back to APS troubles, I can't help but think that some plain, old-fashioned, forthright honesty would go a long way. I recently read some posts from an APS wonk claiming outright to an HT group that there is absolutely no di...

Romy, sorry if my outspoken attitude toward Pure Power bothers you, or your own solution to the problem has blunted or greatly narrowed the focus of your current interest. I think you mostly get where I'm coming from and you just don't like it, and y...

The Carl Sagan’s suggestion that he would rather "know than believe” is good tool for sales personnel, priests and pitchers and the politicians of nowadays. Since perception is really it is imposable to “know” with any degree of certainty without sub...

I presume that whoever read this thread have gone over my comments about the Sound of the former PurePower 1050, particulary my comments about the PurePower’s “Super Texture” at the page #5 of this thread. This controversial “Super Texture” was my ma...

[quote user="Antonio J."]I suspect the APS does more or less the same that my friend proposed. It probably has a class D amp which makes some kind of PWM with a so so smoothing circuit, hence the tooth saw trace of the voltage line, some PS which pro...

If the APS works as I described in the paragraph above then the buttery does not filter/buffer the source of ASP’s oscillator and amplifier. In this case I would like to get rid of the buttery and do not let the APS circ...

[quote user="PurePower"]I'm sorry if my post seemed to be directed at your acoustic noise issue. It was meant to reply to 2 other postings that simply asked if the battery only turned on in a blackout and whether there was a difference in the audio s...

Maybe it was easier for an individual to work with APS before they got the great reviews and stepped up production? Now they have all they can do to fill the orders (and invent new products, of course...).Romy, I believe you got a solution to yo...

Many of the expensive power cleaners and regenerators claim that they do not limit current. None the less, many of these devices do seem to go into a swoon as current demands increase. We all remember the days when these devices were widely con...

A friend of mine asked my last night if I feel that PurePower’s Sound as good as a playback during those extremely seldom moments when electrify is good. It was a good question and I feel that it is worth to cover.
First off all I can not say about ...

Paul,
