Hi Max,If you have buzzing that is audible outside the PurePower case, or audible from a listening position, the behavior is not normal. The probable source is a capacitor. Caps can hum in the same way as transformers - the foil expands and contracts...

Today I have reinstalled my PurePower 1050, it spontaneously blew up a couple of weeks ago. It seems that they installed the latest PCB Version with all the updates and it runs !!The first thing I noticed that the sound of my set is so much better no...

Dear Romy,You said that PS Audio never acknowledged any sound problem with old PP. Did you ever identify something "technically wrong" in the sinewave that a PPP outputs that peoples from PS could work on ?May be I miss your report on that point but ...
|

The PP has the words "winstream" printed on the PCB. I assume they're the ones that make the units for PP.Here's a diagram from their page:http://www.winstream.com.tw/products/RHC-2.htmSend them a mail. They probably know more than Purepower about th...

[quote user="oxric"]Romy, can you tell whether PurePower have identified precisely what made your units to perform as they do and whether that is now a standard feature of their off the shelf units? I am sure many here who might still purchase their ...

The last nigh I tuned the playback and witnessed one of the best sound I had. My playback ordinary doe for but this time it was like last winter – it was way beyond anything ordinary. Obviously the electricity was the factor but this time I was armed...

Dear Romy, your adventures with PurePower appear to be frustrating. As an alternative, have you considered contacting the equipment maintenance department of a local hospital to discuss equipment that they use to ensure pure power to instrument...

Maybe you should get spectral data what your power supply secondaries look like in an case, my suspicion is that we have the exact same issues as with high order crossover networks when our power supplies have "high order" filtration. Maybe we ne...

If i am not mistaken It seems Most High Power UPS in the market like APC or ABB are not good for high dynamic loads (high crest factor like Music signal) and the load transient response of these UPS is not very good at rated power. APC , ABB and ... ...

Spoke last night with PurePower people and have good news.
First, after the “agonizing research efforts” (satire) the APS have discovered that source of fuzziness that I reported above and claim that they have a very simple fix that would not requir...

Yes, but is not the real question *how* different from the Taiwanese company's standard double conversion UPS the purepower units really are. If they are effectively the same topology and components (http://www.winstream.com.tw/products/RHC.htm) but ...

I don't think Purepower Canada has the wherewithal to just close the factory assembly and take a sabbatical while they start from scratch, or better, just return to the old model that mostly worked. In addition they probably have lost their markets i...
|
|
It is good to see PurePower here, and perhaps their representative could clarify how, if at all, their units differ *topologically* from a standard double conversion UPS device. What information the website has shows no significant difference in topo...

Don't get me wrong, I simply wondered if you had fresh news also on that topic. Let's hope that at some point they will remember even if I have to admit that I do not expect much anymore from Purepower......

[quote user="Romy the Cat"]I am very sure that if you buy directly from PP then they will not make
you to pay until you get the unit. I very much do not advocate buying from PP
or from any other manufacture. [/quote]Not correct. However, I am glad ...

Hi George,We did find an email response from Damian to you in early 2010, suggesting that we could think of no technical reason that a PurePower unit would have a problem with +/- 60 volt input. We routinely operate our 230 volt models with two phase...
|
|
Adrian,I am sure you are happy you eventually after years got a Purepower unit after they took yours and "misplaced" it. But if it wasn't for the constant harping on this sorry treatment by you, me and others in these threads who knows what would hav...

I do not see any major changes coming in 2009, nor do I feel a need for them. Recalling all my dids and my thoughts here a brief outline of Audio Projects that I will be involved in 2009 and of cause anything else might come alone in future…

Byzantine Empire and PurePower.[quote user="spytsi"] Everybody here remembers that Romy's initial acquaintance with PP products was through model 1050; at some later point he upgraded to model 2000. Since then quite a few user opinions appeared ...

If you follow this thread and my successes and tribulation with PurePower regenerators than you remember that I had problem with sound running two PP2000 for right and left channels. So, I had everything, including my DAW plugged into on PP2000,...

ArmAlex the fun thing is that you read Romy posts here without understanding his ideas and copy paste Romy instructions in your Audio system and the result is lower than those audiogon guys (an example of your audio logic -> you buy gryphon spea...

[quote user="oxric"]….However, as I have said previously, my interest in Fane is strictly limited to this production run and nothing more sinister as you seem to insinuate. On the other hand, you had no problem being quoted on PurePower's site as a u...

This subject is interesting but unfortunately there are more options then time in life to experiment with all of them. The idea to use fatter cable is right atop of surface. It is not about current caring but the lower impedance of the cable. Remembe...

Eli,
I was in the same place at one time and accepted my listening as it was in relation to electricity. You say
"When [electricity] is good great and when is ok I live with it and when is terrible I just walk away".
This is fine to say...

[quote user="N-set"]
They have figured out a way to
eliminate this but it requires making a new PCB to replace one in the
PP2000. So they say they are going to make these and hopefully the
replacement PCB will be given to me in a month." [/quo...

[quote user="AOK_Farmer"]I think what they did was to put filters, maybe just a simple capacitor on the AC side to try and reduce the noise that the units inject back into the ac mains. Perhaps they were getting complaints that the units worsened the...

Well, here is good news:

Among many good improvements the bypass is there!!! Hallelujah!!! Still, there is no remote control option for bypass, there is no distortion analyzer at input and o...

I had sent my PurePower+ 3000 in for an
“upgrade” (one of many!) back in December 2013 to resolve an issue with a noisy
choke when under load. It still has not
been returned 5 months later after multiple broken promises by the company
president ...
