Bill, if you have fearlessly ordered a PP2000, and if you actually receive a functioning unit at some point, I hope you will find a way to test and compare it directly to Romy's repeatedly and selectively modified (yet still not correct...) unit. Th...

Thanks, Bill, I do not need it yet. I estimate that I am a good 2-5 weeks away from the time what I might just stat play with my playback at any more or less refined level. Also, I would like as well you to compare your PP2000 with mine, not that I s...

I was moving today my speakers back and forth and fine that the 14.5 foot is the most suitable distance between the speakers for my room. To get more precise positioning I would need to get better sound, so I will take my PP2000 back and will drive e...

Yes. Their is a direct correlation between surge current and dielectric materials dielectric constant. The voltages in question are high enough to use a thick dielectric material and just as with the effective resistance of the capacitor, there is a ...

Romy:You may in the meantime build your own battery pack to increase the playtime you get from batteries. When I last spoke to PurePower (I placed an order for a PP2000 in another life and then cancelled the order), I asked whether they would pro...

I got a contact from PurePower this morning and they requested some times to look into what is going on. It was not exactly pleasant that they took my behavior as my personal attack against them – it was absolutely not my intention and I have no pers...

Only on this website do I find myself laughing and crying reading the same post.[quote user="Romy the Cat"]PurePower do not need to collect opinions, including from me. The need to produce a product that has default operational sound and the made of ...

I don't have a scope, so can't measure the output of my particular unit. However, if I were to guess, I would say that my unit probably falls alongside your #2 unit. When run from AC, the bass disappears and the sound becomes bright and edgy, to the ...

That is funny and I kind of forgot how it is. Got home and plugged the SMS digital crossover into the chain of my new midbass horn. I sat to lie different crossover sloped. The bass from the midbass horn was like somebody hit me in face with a wet sp...

[quote user="Romy the Cat"] OK, I agree – it might be not necessary as PP2000 does produce fine electricity in a convenient package. Furthermore it violates the rule that I try to follow in audio generally: define snick objective and ONLY then re...

To recap what I have said before, the issue is bad electricity, which makes your stereo much like aliving thing with tempermental moods. The same way that a steak can change from a sizzling, juicy tender delight to a cold greasy lump after being chil...

I am talking about the fans and the capacitors. I have a PP2000 and the more you load it, the more the capacitors "whine".Nothing from the speakers themselves. It is a pity that cooling is not passive taking into account the efficiency announced. I g...

I ordered a unit at the end of December and was told it would be shipped in approx. one week. However they ran out of units and the delivery time will probably be the first week of February. I'm tying to maintain the patience of Romy. The only thin...

The new hours that I am hatching now has some funny electrical setting. The house owned by a guy who is retired electrician ME (Master Electrician) and he did a very good job with wiring. The house has 200A line with dedicated 100A subpanels. If beca...

Hello i was told by the shop that sold me my pp2000 that the unit was not designed for battery back up in normal operation. That battery back up was added only for cases of power lost. Ive had that happen only once in the time ive used the unit. Now ...
|

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="Beav"] What I have is a subwoofer made by ACI; no information on the amplifier used other than it uses a two prong power cord, no ground. When I hooked it up to the APS 2000 I got a very loud pitched hum. Taking if off the 2000 an...

"Success" equals better except for added hum? How lucky is APS to have customers like this?!?Any dimmer switches within a mile and a half of the system? Any variable inductors connected anywhere in the house? Root out anything like ...

[quote user="drdna"] 3. When the PP2000 is plugged in, the neutral AC connection adds an additional ground reference. [/quote] Adrian, if you make such an assumption than it was why I advised you do not plug all your components into PP20000 but to pl...

[quote user="drdna"] As I said before, the perception of the audiophile imaging and soundstage is really gone. [/quote] I think you might revise your view about imaging in future. No one cares about soundstage but with imaging it is a bit tricky. One...

By definition and code, a separate non-current carrying ground is required for all outlets. In every house I've lived in, the ground is a separate thick copper bar that goes deep into the ground (the earth outside the house) and that is the gro...

The PP2000, eventually(!!!!), demonstrated something that I was looking for long time. Years after year I read and listen comments of different audio people when they describe benefits of different power treatment devises and year after year th...

Yes, the HF do slowly return with PurePower 2000 where they shell be. It very slowly the PP2000 look like dials itself back to “neutrality”. I begin very leisurely to roll back my tweeter and the plate current on my MF channels.
The Cat ...

Wouldn't it be nice if the PP2000 finally allowed a "qualified" system to produce realistic HF, where the treble sounds clearly originate down where they are supposed to and the highest frequencies are "inaudible", like they're supposed to be?&n...

After the endless battles with bad electricity, great news that you have found one, and possibly two, good solutions. I can vouch for the terrible electrical infrastructure and great radio stations Boston has to offer. Some days my system sounds pr...
