... this last time ive been doing some "ear" experiments and trying different setups of filtering . Just a question regarding a phenomena that im having , ive tried some ups/on-line regenerators and I think they tend to "smooth" all music but they do...

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 ...

[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...

Romy, this is very interesting indeed. I'm assuming that the sonic difference between these two files is in line with the sonic difference you hear between bad and good 'electricity' days when you're just listening to music, with no recording chain i...

hmmm sorry Romy for the lost of your pp2000 ....I would like to share one opinion from a technician that lives in Japan and lived in Chile . We were discussing the issues of electricity and he said "Lines in Chile are poor quiality , cables are too t...

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...

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"]This is why I am a bit skeptical
and with big worry hear news that PP did some improvement. [/quote]Since (at least comparing PP2000 and PP3000+) PurePower is still effective, the one thing we can say is that PurePower has...

[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...

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...

[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...
|
|
Have a hum through my center channel speaker, the SET amp of which sits directly in front of the pp200 about a foot away. It is not relaTED to the DC offset of the 2000 as adjusting that does nothing to the hum, and running the amp from the wall rat...
|
|
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...
|
|
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...
|
|
Bill, have you been using and reporting on Romy's unit, while you wait for your own unit to arrive? I ask because if this is the case then we still have no evidence that there is a second viable unit out there.It sounds like the AC/DC converter/char...
|
|
Yes, you are right, the voltage divider from 6.3V across 47K and 10K resistors shall give not 0.9V but 1.1V. However, the numbers that are in circuit are not something that I saw in my dreams but the actual numbers that I measured. I might presume th...
|
|
Ok, I think it is a good time to deal with room acoustics. All infrastructure problems are set. The Midbass horns are underway; the electricity will be investigated but as now is addressed by PP2000. Macondo and Milqs are inhaled, the system is up. I...
|
|
It is detailed elsewhere on the website, but when I sent my PP2000 to be repaired, I received endless promises. It turned out the company was going through a major crisis with a Chinese manufacturer and distributor trying to usurp the brand. They eve...

I am very convinced that in Adrian case he has more t...

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 do not know, Meiko41. I am not a speak-person for PP2000 and I am in very same boat as you are. They told me that they have a modification that would make the fan more silent and they promised to send it to me… a year ago. Frankly I did not insist ...

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...
|
|
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 ...
|
|
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...
|
|
Adrian, I have alternately revelled in and anguished over this for some time now, the lynch pin for me being the electricity. Yes, I can generally hear any change I make to the system, but it is consistently the quality of the electricity that ...

|
[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...
