Paul,I finally received my unit in February 2010. After installing it there was an immediate improvement to the sound of my system. I live in an apartment near downtown Boston. My playback varied from day to day. It proved to be very frustrating ...

[quote user="PurePower"]We routinely operate our 230 volt models with two phase +/- 120 volt input.[/quote] That's interesting. I use a couple of 5KVA balanced transformers. I tried to feed my 240V PP2000 with one of them, but the output was non-symm...

I've now been using three of the PP2000 now for 6 months and in that time There have been no further hiccups since one of the fuses went out. They are giving me the best musical enjoyment I've had from my system in 30 years of trying to cure my elect...

[quote user="Lx_"] Well, this is consistent with the behavior I have. I can hear electrical devices behind the PP, especially those of the switching PS type: computer screen, laptop charger, DSL box, printer, SAT decoder... Good luck finding electron...

Every day that I listen to my system, I thank God for Romy's perseverance with the pp2000. For the past 25 years I've fought the crappy electricity that comes to my house in the woods with everything from banks of 8 massive 2 and 3 KVA isolation tran...

I got my last PP2000, after the repair was done. My second new unit works since I got it repaired; it runs the whole playback, sounding very well and my attempts to add a second PP2000 led, as I described to worsening of sound. In the very deep core ...

|
Very interesting. Mine are 6 feet apart with the left and right controlling the amps on top of their own cabinets with source equipment and amps at least 3 feet away. The middle one supplying the source components sits on top of my main stand directl...

[quote user="Romy the Cat"]A few post above Bill mentioned that he run his PP2000 from AdeptResponse power conditioner. I am not familiar if AdeptResponse helps to separate one PP2000 effect another. I am not also familiar with AdeptResponse its...

As I said before, in many if not all instances the provisions for “bad electricity” are deeply entrenched into the design of our playbacks. A few days back I took advantages of some new possibilities that PP2000 offered and made some changes in playb...

[quote user="Paul S"]Adrian, may I assume that if your unit was finally sorted out, then you would have said as much by now?[/quote]The issue is unresolved. The unit still emits a buzzing sound when it is plugged in. I have sent a few e-mails to APS ...
|
|
After many unanswered e-mails, I got word from APS today, who said they have had a few customers with similar issues and that it seems to be system dependent. However, they also said that they were working on a way to fix this that they might have i...

|
Well, I think the short answer is yes.What the people over at Technical Support have told me is that this is due to the power supply design of the amplifiers that are being driven by the PP2000 and that it seems to be characteristic of certain types ...
|
|
[quote user="Bud"]Sounds to me like your switch mode transformer is doing the buzzing... There is always a turn on buzz, but just for about 10 seconds. The original one had a noisy fan also, to keep it from self igniting, perhaps that is your actual ...

Well,
I have to tell you, Meiko41 that I was pleased to see that a local guy got a new PP2000. I kind of on the verge to get another PP2000 and this was a good preview what newest state of the PP2000 is. Even it was very clear the with PP2000...

Will do if I can get a review sample.

Have purchased two of the units for evaluation, using them for right and left channel and sources. Have also been using Romy's unit for the surrounds. Each running at about 35-45%. Sound is phenomenal; best I've ever heard from my system. One problem...

[quote user="Paul S"]Every case of a "dedicated ground" I have seen, including my own, involves only the redundant "ground" wire. The "ground" wire may not be useful for every component, and it can actually introduce noise in some cases.[/quote]Toda...
|
|
Considering that PP2000 isn't plugged into a dedicated line and that line can be shared by other electric devices plugged into the grid, I wonder if the hum noise is getting into the PP2000 not from the ground wire, but the neutral wire for some defe...
|
|
Something very interesting happened today in my battle with the incessant buzz in the PP2000. No, it did not go away unfortunately, but I learned something new.Perhaps inspired by the recent discussions around the original pressings, I decided to spi...

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...
|

Nice to hear that it eventually produces less noise. At least it becomes clear now that it was far from being as silent as they were so quick to claim.Do you know if they plan something for previous buyers of PP2000 ?I would love to ask them myself b...

Had an interesting problem with one of my 2000- units last night. Was listening to Rite of Spring fairly loudly and about 8 minute in there are two strong bass drum thwacks. On the firast one, onr of the units shut down all of the outlets, but didn't...

[quote user="Romy the Cat"]From what you describe I conclude that you have ground loops regardless of the PPs and the PP juts highlights the problem.[/quote]This may well be the case. I can't even remember the exact components I was using last year (...
|
|
Well after getting little communication from PP I decided to sell my unit. The last communication from them was on 1-7 here is their response:Hi Steve,The reports you have provided are giving us valuable clues to the cause of the noise, but are not d...

Perhaps the PP2000 doesn't like working with inferior equipment!It seems obvious but did you try running the PP2000 from different wall outlets ? I know it should't make a difference.R Weissman...

this weekend I plan on taking the cover off and giving my 2000 a good cleaning. its been almost 4 years and ive been getting some ac sounds at the speaker recently. I need to replace the battery as it has ran its life cycle. hoping this cleaning make...
|

Hi Emanuele,FWIW, I've been disappointed with my PP2000 (the 230V model). I love the sound then it's running from battery, but think it totally destroys the sound when running under 'regenerator' mode. And as Romy has pointed out, this is totally una...

I got today my second PP2000. This was the worst sounding unit, the one that I used for over 2 year, was fine then was upgraded to the new version and lost it sound. The first fix of the upgraded unit was not successful but this last one looks like m...

[quote user="Paul S"] Didn't you first become aware of MF "problems" when you got everything else working better via the PP2000, and the MF wound up dropping back to weak sister status with respect to system-wide PP2000 benefits? [/quote] The PP2000 ...
