 PurePower+™ 2000

Well, the results of my completely subjective test are in. Music with the Pure Power+ units as the AC source clearly sounds best. 

Lows are defined, not muddled, and not "thuddy".  Mids and highs are dynamic, subtle, and clearly & distinctly audible.  I use the Pure Power+ units exclusively, and NEVER switch to another power source.

The low bass notes were both heard and felt with regenerated AC - not so with PG&E utility power.  I could hear that a bass was being played, but could not feel it at all, with plain old wall power.  With regenerated AC, the bass was delivered with far more definition and coherency.  That's probably why I could feel it at 12 milliwatts!

The noise floor was similarly reduced with regenerated AC.  Not being an audible thing, it's more the way the listening experience unfolds with lowered noise floors.  Here too, the way the music arrives at the ear is more present, with less in the way of the music on its path from disc file to your brain.  I hope that makes sense ...

The midrange was open with regenerated AC; flat with pg&e.  Wall power was like listening to Iggy Pop's famously low fidelity recordings: if he didn't do it on purpose, it's as if he did.  His music is very funny because it uses virtually no dynamic range, and is just wham and bang - but great if you like punk of the 70's and 80's.  That said, I do not want all my music to sound that way. PG&E made my system sound non-dynamic.  Regenerated AC allowed the full dynamic range.  I could hear and feel the difference.

I seem to be in the habit of thanking you.  So, let me do it one more time!  Thanks so much for everything.  I am thrilled with the regenerators.  They are easily the best improvement in sound I have ever made - and there's protection from the whims and ravages of PG&E to boot.  What more could an audiophile ask?

 PurePower+™ 1500

Now I'd like to discuss the best thing that's happened to my system in months, the PurePower line of AC regenerators. I've been running all of my equipment through three of their PP 2000 units for several years now and have been more than content with the sound of my system. They do an excellent job of cleaning up the AC grunge, giving the best sound yet out of my system, even on nights when the electricity is atrocious.

So about two weeks ago, Richard Janzen and his lovely wife Donelda came over with three of their units, a PurePower+ 3000 and two PurePower+ 1500 Regenerators...

All in all, there was a significant enough improvement over the older units to require me to once more dig into my retirement fund for immediate payment for them.

PurePower+™ 3000

After hooking up the PP3000+ to my audio & video system, I noticed the following changes in sound. 

When playing any audio source (CD, Vinyl, DAT, FM tuner) the music seems to come from a much quieter background. On really good recordings, this can be rather startling when music has silence between notes, then starts again from a “blacker” background. The bass seems much more organic, acoustic standup bass sounds more “woody”. Electric bass has more punch. Although not consistent enough to be sure, the high-end (treble) seems a little smoother on some recordings, but not all. The midrange seems to have more space around vocals & instruments, with more “texture”. When using my analog  tuner, once a station has been “tuned”, the center channel tuning meter doesn’t move! When bypassing the regenerator, the tuning meter wobbles around, and sometimes requires “re-tuning” to center the meter. The sound from my Stereo is now consistent, regardless of when I listen. Without the regenerator, my stereo sounds best after midnight, when there is less use of electric by commercial & residential users. It’s like having your very own dedicated electric company for your system! 

Now on to video. Wow! It’s like we got a new TV. The color is way more vibrant, like turning up the color control. This is evident the second you turn on the TV, the colors “pop” without being over saturated. I have Verizon FIOS, and thought my TV was performing at its best. Not so! The PP3000+ makes such a big improvement, like going from regular TV to High-Definition TV. The picture is that much clearer. I can never go back to not having this brilliant piece of engineering. Pure Power LLC is definitely on top of their game with these new “Plus” units. 

Thank-you from a happy customer! I appreciate everything you did for me. I love this thing!

"Sound. It is no brainer: the new unit does sound notably better then old one. 
It is across the board: bass, dynamics, HF noise, in any audible 
characteristic. ....It was very interesting to switch the new unit to operate 
from wall to battery (with no bypass mode). The sound is virtually the same... 

To summarized everything. Pure Power after the famous Chinese accident had to come up with own version made in Canada. They did. If the PP+ would be 
identical to older Chinese-made units then Pure Power world have logical 
problems. Luckily for  Pure Power, ..., the new PP+ units are sonically more 
advanced than the older PurePower units. It shall give to new PP+ some 
momentum. I think the main attention for Pure Power shall be functionality, 
stability of operation and quality control. They do have a good product in my 
view ..."

So, I connected two of my big Goldmund amps to the PP3000 today.  I always feel like I get incredible sound late at night when the 200 pc's in this building are turned off.  Well to my surprise the sound with the two amps going into the PP3000 along with a bunch of my front end stuff is giving me the same sound in the day as it does at night.  Just like you said it would!

... some initial feedback on your PurePower+ 2000 device:
much whiter whites, much more deeper blues, blacks and reds on my Kuro plasma. 
Sonically, my system never sounded better; incredibly clear clean "punchy" lows via the sub-woofer; highs and mid range very very "crisp". Hearing things I've never heard before when I watch Blu-Ray DVD's.
Well done!! on your newest PROD release of the PurePower+ 2000 device.

"The experience of this thing – your 2000 plus – is mind blowing. It’s a gigantic, huge and massive improvement in ways that I couldn’t even have imagined. A whole different stereo system, a whole different sound stage, whole different bits of information, bits of information that I hadn’t heard before, bass information that is massive by comparison. So it’s huge."

"A lot of "grunge" is gone. I hear things I have never heard before. There is a "sweetness" that wasn't there before. Dynamics are better. Bass is both fuller, and more tuneful or "fast". Tonality is wonderfully pure. Most importantly, I find myself wanting to listen more; and not getting tired. This is just what I had hoped for. And I have a happy feeling that is similar to what I used to experience in my room, before the gremlins in our electronic world gradually took over. It's what I remember music used to be like at home! It has been a very long time, and I didn't realize how long.

So ... thank you."

All I can say is "WOW" the 1050 is the best improvement in my 35 years of High End audio experience!  The "Enjoy The Music" reviewer was right!  My Magnepan 3.6 speakers with  the Pass Labs XA30.5 amp is producing "State of Art" sound quality.  Very dynamic, 3D, pure, sound from the bass to extreme high frequencies. I would have never expected that.

Could not be more pleased!  Well worth the wait."

On two channel SACDs and computerized digitized reproductions of studio analog tapes from the 50's and 60's, the sound was unbelievable, the best my system has sounded in it's 28 years of existence. And the sound has not varied by day, time of day, or programming. In other words, the units have cleaned up the electricity to the point where its quality never varies.

.... I’ll be selling off all of my other AC filters, and I suggest you do the same and purchase one or more of these units before they are inundated with buyers as their supplies of the units are limited."

"I am a bit hard to impress any more but the PurePower has managed to bump the performance up a notch. I am now able to run my whole system from one power conditioner and actually love the results.

I kicked it up a notch this evening to put the unit through its paces and see if it it holds up under some "pressure". Hugh Masekela "Hope" CD was chosen for its exemplary clean and wide dynamic range. Cranking up the sound to beyond the "usual", the drums exhibited stupendous slam, crispness and articulation. The Lamm amps hold up to the punishing 1.8 ohm dip at 90Hz that Wilson Sasha presents easily and I'd say this PurePower unit will hold up to anything I can throw at it with its 2000VA/1400w power rating and the demand from the amps. I am happy.  Transients are crisp and well controlled but the input side of AC does dip even further than 115v  The output side is still rock steady at 120V.  Good enough for me."

PurePower™ 2000

Audiophiles are a funny group. Compulsive, often manic depressive and deeply committed to their audio systems. Ask us to describe the latest improvements and we become Oscar Wilde dipping into our deep hat of colorful descriptive adjectives. What happened last night left me drawing a complete blank as I gasped for words to convey my reaction to a product I am evaluating for my company.

Pure Power AC Regenerator Model 2000 is the product. Damian Janzen is the co-owner and if he doesn't walk around with a "Viagra-like grin" on his face all the time, then he is simply too modest. In case I am boring you, let me cut to the chase. With a completely straight face, I can stake my professional reputation on this statement: This  is the most astounding single product I have ever listened to in 35 years of this hobby.  Maybe because its inexpensive ... maybe because I don't see people camped out on street corners claiming their lives have been changed by this thing... or just maybe because I have not read about it or heard about it nearly enough in the mainstream press.   Whatever the reason, I don't understand how it isn't hailed as  the cure for cancer or the world economy. Oh yes, it is that good.  This is from their site:

 “The PurePower™ APS (Audio Power Supply) provides truly regenerated pure power regardless of what problems exist in your utility supply. This is accomplished through our double conversion technology.  We convert the incoming power to produce a clean DC current, then recreate a 60 Hz, 120 volt AC wave-form from the DC.  No spikes, sags, surges or other power disturbances can be passed through from input to output.”

I found out about it from a very erudite audio buddy of mine who has Boulder amps and Wilson Maxx 2 speakers. He maintained I was  "out of touch " by not carrying this line.   Out of touch... how dare you sir! I read everything printed in page and web text, I am the obsessive compulsive one remember?

Sonics: Detail you never knew existed on recordings. Microscopic detail in fact. Weight of cymbals, density of plucked string, depth of percussion and voices... oh my .... voices that defy you to say this is an electrical reproduction event.

Tone: Nothing can prepare you for the kaleidoscope of tonal purity this product delivers. Period, end of discussion.

Transients: The acceleration from midnight to attack is startling. You will be digging out every percussion disc you own and rushing to the computer to order everything you can get with  explosive orchestral passages.

Purity: This is difficult to describe but it all sounds so natural and effortless. Dynamic swings take you by surprise but never at the expense of ease and continuous flow.

The price: You will be wishing you got a few of these before Damian gets wise and triples the price.

System: Aerial 20 T speakers, Aerial SW 12 subs. Conrad Johnson LP140 Monoblocs, Wadia 781i cd-sacd player, David Elrod Statement Gold cables, Critical Mass Grand Master isolation RPG acoustical treatment. All lines are isolated - dedicated from a separate sub panel, separate grounding rod for this system …. every piece of gear on its own circuit.

Pure Power 2000 significantly enhanced the sonics over and above what my previous high end AC conditioner provided: greater dynamics with more punch and liveliness, cleaner and faster transients, better defined and tighter bass, more open highs yielding greater delicacy, increased resolution of complex orchestral passages, cleaner and purer harmonic texture, easier to perceive nuances and longer decays, more natural and relaxed presentation, and enhanced soundstage elements: depth, focus, air, separation of instruments, and transparency.

Immediately apparent now is the startling clarity offered by the music playing system, like a window glass that has just been wiped clean. Noise floor is very certainly brought down by a mile. I found myself now admiring the focus of each and every instrument within the deep, wide sound stage!

The vocals are now very palpable and believable. In fact so good, with recordings that have it, you can certainly hear a face in the room too! I really liked the Pure Power APS 2000 powering my system, it's probably one of the best power line solutions money can buy today.

I, personally, am blown away every time I now watch a DVD! Has taken it to a whole new level. Let me tell you .. I didn't know my equipment was 'this' good .. until now! I could go on and on .. but I won't. I know you've heard it all before.

"I appreciate audio devices that instead of demonstrating their own qualities, force you to think about sound. The new PurePower 2000 is turning to be such a device. I have so many ideas and so many thoughts with the sound the 2000 produces that I truly surprised myself. Today, spending many hours with my new regenerator and listening to music, I could not hold myself from laughing as many times I caught myself acknowledging that this or that aspect of the sound was exactly how I always insisted it should be. It was like being an orphan and suddenly discovering one's own parents

Somehow the PP2000 surgically removes all negative manifestations that are typically associated with bad electricity but keeps everything else absolutely un-affected.

After spending those 4 days with the PurePower 2000, I suggest that they adopt my proposal for a new slogan: "We do not 'f ***-up' your Sound." As far as my familiarity with power treatment devices is concerned, I know of no other power company or product that might be entitled to use this slogan.

It looks like the PurePower 2000 resolves the problem with electricity once and for good..."

I'm a real advocate of PurePower.  I'm in the UK and suffer from "dirty mains" - lots of voltage fluctuation and harmonics that cause the torroidial transformers on my valve (tube) amp to hum badly.
I did a lot of research into various techniques to "clean up" the mains, and decided to go for regeneration.  Frankly, nothing else seemed to make sense to me - I'm not an electrical engineer, but
the thought of trying to resolve mains quality and interference problems using "smoothing" techniques just didn't add up !
So I spent my UK£ to buy the 1050 and the difference is simply astounding.  The overall system quality is significantly improved - the noise floor seems much lower and subjectively the sound is more dynamic or "agile". 
I'm a vinyl junkie with a top-end system (VAC Phi-Beta amp, Sonus Faber Amati speakers, Oracle 1.1 Ultra-Wide cables, Roksan TMS2 T/T with SME V arm, Clearaudio Insider Ref Cartridge and Clearaudio phone stage) and I was not expecting to notice such a big difference running the system on the APS,
but my ears tell me otherwise !

The level of improvement this added to my already exceptional system was akin to a total system upgrade; it did more than I could have imagined a power product could do. Add in all the protection, ability to run on battery power and the fact that I can safely use my system during our frequent Florida lightning storms without worry, and I think it’s a steal. I am keeping this in my system and recommend you get one, too.

In the end, this is the best, most performance-oriented AC power device we have tested at

I have come to the conclusion that the PurePower 1050 is the ultimate piece of electronics for video use. Combined with the vast improvements in color and contrast, something that many display devices lack in this day of fixed pixel digital displays, it provides better backup for safeguarding your display by allowing it to properly cool off in the event of a power outage."

"With the Audiophile APS in use, the various rhythms and textures that he used were reproduced with much more clarity. The different types of cymbals used could be heard much more easily. The increase in clarity was not accompanied by any hardness or glare, and that's a good thing. Tonally, music overall from top to bottom seemed richer, more full sounding as compared to the sound using the PS-Audio P-300."

"I am not aware of any other power line regenerator that has all of the capabilities of the APS 1050. Considering price, performance, technology and style, the Audiophile APS PurePower 1050 Power Conditioner receives my highest recommendation."

"I live in central Fla - we get daily lightening storms for 6 months of the year which will test the toughest of PLCs. One of the reasons I'm purchasing a 1050 is because of what sounds like impenetrable surge protection."

"A few years ago, I lost about $8000 USD worth of amps (which I thought were well protected thru a Tice Powerblock 3C) and last year I lost a board in my prepro thru a BMI Shark PLC. The batteries (conversion to DC) seem an integral part of the design and the surge protection so I just wanted to ensure that the batteries were robust and that I'd have some way to know when to replace them. Replacing $400 worth of batteries is trivial compared to damaged equipment."

"Looks like a terrific product and unique in the marketplace - thanks."

Audiophile APS 1000 

“For our test, we used a pair of Bryston 7B SST monoblocks and the Acoustic Arts power amplifier. Thus, we had two very power-hungry systems that can draw as much as 1000 watts when in operation… The APS handled the loads effortlessly when in the regenerating mode. We then pulled the plug and, to our utmost surprise, the system(s) continued to perform as though power hadn¹t been interrupted at all.”

 “…the APS … picked up subtle distinctive and complex underlying tonal structures never ascertained before. Midrange clarity improved as well and may be the result of the amplifiers¹ noise-free performance. …the APS allowed better, more clear-cut imaging, focus and time-based accuracy.”
