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...

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 ...

Look what you have done to jack up pricess of vitavox (nobody was buying before your wistle) , Micro Seiki (gathering dust after Art Dudley wrote they bored the hell out of him) meittner dacs (suddenly the most musical in the market ;) Lamms (which a...

[quote user="steverino"]Again I would ask people who are reporting problems to state whether they have the original PP or the Plus version made in the last few years. I assume Adrian had an original version with a hum problem which was incautiously r...

[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...

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 ...

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...

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...

[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="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...

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...

[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...

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...

[quote user="Romy the Cat"]I do not remember that “recommended” APS. I do insist that it is the only devise If does what I want a power devise to do with sound. Is it as recommendation or motivation to buy for others? [/quote]Actually, Romy specific...

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="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...

"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 ...
|

Romy,I agree with the very nice summary you have made of the situation. You remember that I struggled for a couple years to get PurePower to return my PP2000 which had gone for repairs, but ultimately they replaced it with a PP3000+. I just have to ...
|
|
Romy , you are right , pure power affects on wall AC quality, when a pp3000 is connected to wall ac (the TV not connected to PP3000) then the picture quality of my TV decrease. allways I use only one pure power 3000 and other pure powers are disconne...
|
|
It is true never send your unit back for repair to Pure Power. Mine was never returned and my money was never refunded.I agree the sound of the battery was the most pleasant and quiet when I had my PP2000. It is an approach to the problem, but it is ...
|
|
SOS, please note that your PP 2000 does not isolate one component from another within the reconstituted 60 Hz circuit. It only isolates those components from the noisy and variable wall voltage. Since you think you must isolate your TT and phono stag...
|
|
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...
|
|
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...
|
|
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 ...
