The Purepower state at their site that efficiency of the unit is 89-92% depending on load. I presume that they meant the power factor correction that need to be taking to the consideration. In my case my two 6-ch Melquiades run from two new PP2000. M...

I have written before that Dima is at the finish line with his new power treatment invention.

BTW, Dima’s regenerator has a new name Avicenna Power Device and it is how it will be refered in future...

Paul. GSC = goodsoundclub I have worked with Richard (pure power owner) and i know the problems of customers but i think paypal is a good way to shop from Richard. Ask Richard to send you video from the unit before paying to him. Recently 3 or 4 pure...

Paul,
Ok, I would agree with this. The power handling is the factor that I forgot to mention. The Japanese home drivers are rated for a few watts vs. the pro driver are rated for hundreds watts. BTW, some of older pro drivers (like my Vitavox) wer...

Well, there is no question that power companies pay zero attention to the complaints of audiophiles, neither shall they. The power companies are in pusses to sell power and unhappiness of a done or so fringe consumer is understandably not their conce...

Are we all in agreement that up to now "the best power" in terms of sound has been the best wall power?Maybe this has something to do with the fact that on a good day there is a LOT of current pushing the "best" wall power into a system tha...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

Well,
The most miserable things about electricity that you never know what to do. I had in past different filters and mny imaginable power gismos, a number of isolated transformers, balanced transformers, regenerators…
For a couple years I was runn...

I am looking for a good external power supply for ATX motherboard and Sotm pci to usb card.i need 12v, 3.3v , 5v, -12v , 9vsometimes i think if i use CEC TL0-X power supply it may help but i did not measured it's output voltage.CEC TL0-X has 4 transf...

Well, there is always a field for concern regarding the size and internal resistance of the battery. Relatively small power bateries do make negative impact. Another field for concern - musical quality of the mains power in Russia an...

Looking again at the NAT Audio Magna amp, the amps around the 833A, GU81, 50TH, 1000TH, GM100 and many other SETs that try to use powers transmuting tubes I feel that the entire endeavor of powerful SETs shoot itself in a leg.
If a person has too de...

dont know if the posters comment was meant to sound negitave or positive about this thread and you. myself and countless others who use PP2000 because its performance and clean power is what our hifi systems love. PP2000 is delivering the power and t...

Romy,
I ran the tube conservatively at 40W, because it is still breaking in, and I do not want to push it too much power to damage it (then I will have to break-in a new tube all over again). This amp can give max power at 20.35W (12.76Vrms into 8 ...

Romy,do not spit in my eyes as I do have solid state PassLabs 350.5 but even with this 50W Class A amp (push pull) it is exactly the same problem if it is switched off completely even for a short while. I can take ~ 2 - 3 days to be back to norma...

TonyB,Romy has commented on the perceived differences between the 2000 and 3000 as well as the older units and the Plus units earlier in the thread.I am thinking that the power utilization level of a system may be a significant factor in perceived be...

The situation reported has been presented unfairly we believe and includes completely false information regarding PurePower. We were working to solve a problem with a PurePower installation in California for over a year providing three replacemen...

Romy, Just make a good power generator that will not screw up dynamics and not be affected by dirty power. You had some ideas before (60Hz sine wave + amp with a lot of power) and you have experience in this matter. That will take care of all folks ...

The first goal is the best sound possible, taking every advantage to get it. Since the [crappy] [wall] power source is such a big factor in the sound we get from hi-fi, I could see designing line-level stages for use with batteries as a possible...

[quote user="N-set"] Do you also suggest getting rid of the chokes at the power entry?[/quote] I am surprised that you ask those questions. Who cares what I, you or somebody else think or suggest. You have the input filters in please, when the unit ...

Hum is a multi faceted problem. We have identified 4 completely different causes of hum in amplifier power supply transformers exacerabted by AC power problems - and that kind of hum is not even the most common hum audiophiles have to deal with. ...

Hello Romy,I am no power expert but here are my observations on your situation.Even though a PS Audio and others create a perfect AC sine wave this does not seem to be the answer, even for low draw front end components. It seems that some type of&nbs...

I touched on local electricity problems in a recent electricity post. Briefly, the local nuclear plant has been shut down by concerned politicians after "leaks" were detected. Setting aside mutated flora and fauna, sound has been worse more of the ...

[quote user="Paul S"]Scott, is it your specific aim to configure an enclosure to "effectively" lower driver Fs? While this, along with an exponential increase in power, is a proven strategy for generating ULF, it seems like this approach creates more...

[quote user="drdna"] So it would require a new OPT to be made with around 3.5-4K primary impedance. The power the amplifier puts out is already far too much. I always have the volume dial around 1-2, so this will be okay. I don't have such an OPT on ...

[quote user="jessie.dazzle"] Make sure the power switch is off, and connect the power cord.[/quote] Unless you are a republican. If you are then you need to change voltage with power switch on and power cord attached.

I figured out that my site turned out to be a quite good source for “PurePower’s Survival Guide”. It would be nice to abstract the PurePower into a separate subject but it is too much intervened with the thread of “Bad Electricity” that I decided to ...

Dear Romy,I do not know who uses the PowerStation75 so I cannot say whether it is helpful. I use the Powerware 5115 UPS boxes for managing the mains power supply [details on www.nps.com.au under Products and Line Interactive UPS (Corporate...

In regard to the noise issue I had with my Pure Power unit in the past, I never noticed it with my tuner or other components, but I mostly listen to the phonograph. In particular the Decca cartridges are incredible as antennas and seem to pick up all...

Well, the issue you are talking about is very complex. You have many components in your signal chain, that contribute to the noise and signal quality,not only in power supply,but also in the signal chain ckts. The USB A/D converters have their own po...
