More info

The Power Plant Premier, available in both Limited Edition Black and silver, is the world抯 first and only low distortion, high efficiency AC power regenerator.  The device provides regulated, low distortion sine waves from the AC wall socket and can power an entire system.
 
By generating new AC, the Premier produces up to 1500 watts of regulated AC power at an efficiency of 85% with little to distortion or noise.  The Premier has ten outlets, five IsoZones™, a built in power sequencer, THD analyzer, voltage meter, MultiWave, CleanWave and a remote control to access all the features.
 
The Premier is our finest power product ever made and replaces the P300, P500, P600, P1000 and P1200 Power Plants.

The Premier is housed in a scrumptious new chassis whose industrial design is based on the BMW automobile and is the brain child of one of our country抯 brightest new ID talents, Chris Malato. 

Not just another 揵ox?the Premier marries solid aluminum castings, extrusions, milled blocks and hand crafted parts to form one of the most stunning pieces of industrial art anyone抯 laid eyes on. You抎 be quite proud to display this beauty in your system.

A little history
In 1997, PS Audio introduced the world抯 first AC regenerator, the P300 Power Plant.  The P300 was an instant hit amongst Audiophiles the world over and there are nearly 3000 in the field.  The P300 produced up to 300 watts of pure regenerated AC power. 

The idea behind the P300 was based on the principal that filtering the AC with a power conditioner was only a Band Aid solution because it did not address the most important problems in AC power delivery: regulating the voltage, high distortion clipped sine waves, multiple harmonics and noise.

No simple series or parallel filter can correct these problems.  In order to produce perfect sine waves, regardless of the quality of the input AC, it is necessary to add energy back into the sine wave to replace what抯 missing.  That is exactly what the Power Plants do.   

Unfortunately, there was a hitch: the technology used in the P300 was not efficient and up to half the energy consumed was wasted in heat and restricted output power.  So, while the ground breaking P300 would power most preamps, CD players and turntables, it was not capable of powering power amplifiers, receivers and integrateds.

To solve this problem we introduced larger models that could deliver more power, with the largest being the P1200 Power Plant that weighed in at 150 lbs!  The performance of these devices was unquestioned but their inefficiency led to a number of problems and limitations.

To solve these problems we wanted a 揹ream machine?that offered everything in a Power Plant with higher efficiency.  This turns out to be a rather difficult technological challenge that the engineering team at PS has struggled with for nearly 10 years.

A dream come true
The breakthrough came several years ago when our VP of engineering, Bob Stadtherr, came up with a brainstorm that led to a patent application for a new technology and eventually, the Power Plant Premier.
The 50% efficiency of the older Power Plants was upgraded to an astonishing 85% using Bob抯 new technology.

Suddenly it was possible to build a Power Plant capable of delivering almost as much as the wall has to offer. 

Once we had the technology in place we started adding features that our customers had asked for over the years and finally, the Power Plant Premier was born.

The technology
To understand how the Premier works and why it is efficient, it抯 necessary to first understand how the older Power Plants work and why they are not efficient.

The original Power Plant technology was relatively simple: a stereo power amplifier fed 60 Hz from a sine wave generator.  The output of the stereo amplifier was connected to the AC input of the connected equipment.  Each channel of the stereo amplifier produced ?the necessary 60Hz sine wave voltage and when you combined the two channels across a load, you got 120 volts (in the US) at 60Hz.

The Power Plants used conventional class AB power amplifiers to drive the power and these types of amplifiers are about 50% efficient, hence the low efficiency of the Power Plant.  The reason these amplifiers are inefficient stems from the fact that they require a large power supply voltage, generating heat as the signal travels between the supply voltages extremes.

There are other amplifier topologies that are more efficient, like the Class D amplifiers we use in the G Series, but these produce too much noise to be used as a Power Plant. 

In the G Series, this noise doesn抰 matter because it feeds a loudspeaker which cannot reproduce the 500 kHz noise and is unaffected.  But a Power Plant has to be clean; very clean.

Bob抯 discovery was a way to lower the large power supply voltages so the amp was efficient.  To do this, Bob figured out a way to move the entire power supply up and down in lock step with the sine wave generator, so the voltage across the amp is only what is needed, thus increasing the efficiency.  In most other respects, the old and the new Power Plants are the same.

Let抯 take a tour
Now that we know how it works, let抯 see what a Premier has to offer.

Perhaps the biggest benefit is unlimited power.  At 1500 watts there抯 enough power for even the most demanding systems.  Whether it抯 an audio based two channel system or a video based multi-channel home theater, 1500 watts will power pretty much anything you have. 

The Premier takes what the wall AC has to offer and converts it into perfect AC.  Rebuilding the sine wave into this low distortion waveform is a huge benefit to owner抯 of the Premier.  Most AC power is deformed and flawed out of the wall, with the top of the sine wave missing.  The Premier fixes this problem as well as provides instantaneous voltage regulation to connected equipment, regardless of the power demands.

Surge and spike protection are unparalleled in the Premier.  Not only does your equipment benefit from the over under voltage control of the Premier, instantaneous non-volatile spike protection, but the voltage regulating capabilities of the Premier keep everything connected to it at a perfect steady voltage regardless of input conditions.

Inside is an amazing piece of construction.  From the custom built Power Port AC receptacles, to the 1/4 inch thick copper bars that carry the power from the Power Cartridge to each of the receptacles with zero loss, hundreds of hours of design time have gone into the building of this amazing power delivery system.

Isolation from connected equipment.  The 5 IsoZones and 10 receptacles on the rear of the Power Plant Premier keep one piece of equipment from contaminating other pieces plugged into the Premier.

The Premier also has a unique feature that allows it to apply more power than it can regenerate for short periods of time.  For instance, if you turn on a very large power amplifier, the turn-on power required by the amp can exceed the Premier抯 regenerating capabilities.  No problem, the Premier simply connects directly to the wall AC until the amplifier has powered up, then reverts back to regenerated power.

Front panel features
The front panel of the new Premier has a number of innovative features and functions not found on any other power product.

MultiWave and CleanWave
Two of the many features unique to Power Plants are their ability to produce different waveforms. 
Unlike a power conditioner that simply filters, Power Plants can produce perfect sine waves as well as modified sine waves.

MultiWaves were first introduced nearly five years ago.  Invented by our good friend and Northrop Grumman engineer, Doug Goldberg, MultiWave revolutionized the AC power conditioning industry.  Instead of the classic sine wave, there can be advantages to connected power supplies by changing some of the sine waves parameters.

Of all the MultiWave choices we have lived with over the years, the most consistent winner was MultiWave 1.  This waveform, used in every version of MultiWave as well as AutoWave extends the charging time of the sine wave peak so attached power supplies have less ripple.  In the Premier, we decided easy-was-better and offered one choice for MultiWave instead of many.  To our ears, this is the clear winner.

CleanWave was introduced about a year ago and 揹egausses?or cleans attached equipment.  It does this by varying the frequency and amplitude of the sine wave in small bubble-like responses.  The Premier maintains this feature and CleanWave is available via the remote control as well as MultiWave.

THD in and out
No one has ever dared place a true THD meter on an AC power product, and for good reason; they cannot do anything about the problem.  Our power lines are polluted with 3d, 5th, 7th, 9th and higher harmonics as a result of AC sine wave distortion, common in everyone抯 home.  These harmonics generate higher order harmonics as well.  By purifying and rebuilding the sine wave, you eliminate these harmonics.  The two go hand-in-hand.

Why do you care if the sine wave is distorted or clipped?  Simple: clipped sine waves cannot deliver the needed peak power.  Once the integrity of the sine wave is restored, then the harmonics are reduced and your equipment performs at its best.

A common power filter, whether series or parallel, cannot lower the harmonic distortion of the AC without reducing its level, because you need to add energy back into the sine wave to fix it properly.  Passive power filters can only take away, they cannot add, so the sine wave is always distorted.

Power Plants can and do replace the missing parts of the sine wave to produce a low distortion output, low impedance output even under extreme loads.

The front panel of the Power Plant can read both incoming and outgoing harmonic distortion, known as THD.  You won抰 find this on any other product in the world, and as we said, for good reason.

Voltage in and out
The Premier抯 front panel also allows you to measure both incoming and outgoing voltage, or you can monitor the difference between the two.  If the line voltage is 110 volts, for example, the Power Plant will show an output voltage of 120 and a difference of +10.  The +10 is what the Power Plant is adding to the output to keep the voltage steady.

While several of our competitors make long term regulators that either correct these voltage differences slowly (like the AVS 2000) or in jumpy steps like those found on a UPS or transformer based units, they cannot react quickly when the voltage changes are due to power amps and projector demands under real world conditions.  The Power Plant can.

Remote control
Perhaps the one consistent customer request we抳e had over the years is for a remote control to activate the different functions and display options.  The new Premier has an included remote control that can change the display brightness, choose THD or voltage, select MultiWave or sine wave, or activate the CleanWave function.

Rack ears included
Many of our customers have asked for an easy rack mount solution for the Power Plant and Quintessence Power Center.  Each of these products is two rack high (3.5 inch) and comes with rack ears you can choose to add or keep off the front.

Rear panel features
The rear panel of the Power Plant Premier is where the 搑ubber meets the road?  On the rear panel there are 10 AC receptacles, 5 IsoZones, a power sequencer, circuit breaker, CATV connectors and telephone in and out.

5 IsoZones
IsoZones are one of the new technologies we抮e introducing with the new power line that includes the Premier Power Plant, Quintessence, Quintet and Duet Power Centers.  An IsoZone is a separate differential mode filter, fed by a common mode Nano Crystalline filter.

Each of the 5 IsoZones on the rear of the Premier Power Plant separates equipment noise.  All electronic equipment generates AC line noise, some more than others.  When you plug a digital device in the same receptacle as an analog device, the noise of one can interfere and contaminate the performance of the other.  To solve this problem, you need effective isolation between equipment.

The challenge is to build a filter that is effective at isolating noise while at the same time, non-intrusive.  It抯 not difficult to build a filter that has remarkable performance in terms of noise reduction.  It is extremely difficult to build such a filter without using a lot of wire and components that restrict the power delivery of the filter.  The IsoZones use very short pieces of heavy gauge wire, wrapped around small high permeability magnetics to achieve both these design objectives.

To further enhance their performance, each IsoZone is fed from a common mode filter made of pure Nano Crystalline, a remarkable new space age material that has the highest permeability of any magnetic material currently available.  Together, the two filters form an isolation and cleaning network that is both non-intrusive and an excellent performer.

Power sequencer
The new Premier has the capability to drive an entire system and it is therefore essential that connected equipment be turned on in the proper order.  Preamps, surround processors and sources of all kinds need to be turned on first, while power amplifiers, integrateds and receivers should be turned on last. 

In some cases, like that of a Tivo, hard drive music based systems or control setups, it is important to never lose power.  The Premier抯 rear panel power sequencer allows you to select any of the three available power zones and choose always on, switched on, delayed on.  With these choices, you can setup your system to automatically leave power on, turn it on or off via the front panel power button (or the remote), and delay the turn on sequence until the source equipment has been activated.

12 volt trigger
The Power Plant also features two 12 volt triggers.  These triggers are easy to use and will turn on or off the P3 (Power Plant Premier) power sequencer.  Apply 12 volts at either trigger input and the P3 will sequence on the connected equipment.  Remove the 12 volts and the P3 will turn off the connected equipment.  !2 volt triggers are commonly found on surround processors, receivers, automation equipment and some preamplifiers.

Power Cartridge surge and control
One of the more interesting and novel features of the Premier, as well as all products in the new power line is the Power Cartridge AC input module.  Invented by PS Engineering, the Power Cartridge contains the surge and spike protection, circuit breaker, over/under voltage control and the first stage of common mode filtering.

The unique cartridge is the heart of our new series and can be replaced in the field should a problem ever occur.  For instance, if the home is struck by lightning or a surge or spike big enough to damage the cartridge, it easily slides out and can be replaced by the dealer.

CATV, telephone
For those owners of complete AV systems that have connected video and telephone, the rear panel supports two sets of antenna, cable TV, satellite or anything using a CATV connector or two sets of telephones.  Anything plugged into these in/out connectors will be protected from high voltage spikes that can come through these outside world connections.

The Dream Machine is shipping now
The Premier made its grand debut in December 2006 and has been received with raves from every owner  It is, by far, the finest Power Plant ever made.

It represents thousands of hours of design work, engineering effort and lots and lots of dreaming about how to make this the world抯 best power product.

We抮e proud that the Premier has it all.  Regardless of your system抯 configuration if you抮e looking to provide pure, steady, perfect AC that gives your system the best chance of perfection, then the Power Plant is the best choice there is on the market today.

Clean, regulated and efficient power was something unobtainable until the advent of the Power Plant Premier.

Cable Products > xStream Statement SC power Cable

xStream Statement SC More Info

Easy for us to say
It抯 easy to say a product is state-of-the-art.  It抯 far more difficult to create a product that actually IS state-of-the-art! And it抯 even tougher to keep it in the forefront of technology.

The original PS Audio xStream™ Statement power cables were, in fact, state-of-the-art for their time. The xStream Statement used OFC (oxygen-free copper), along with unique shielding and construction techniques to form a cable so superior in power delivery that it set a new standard in the world for high performance power cables. And it stayed 搊n top?for a long time.
 
The bad news is that, even at PS Audio, technology moves on, especially in metallurgy.  The good news is now we抮e able to raise the bar a LOT higher because of new conducting material technology! 
And boy, howdy, is it audible!
 
The new PS Power SC (single crystal) version of the venerable PS Power Statement uses the same great construction and shielding but adds yet another improvement to the mix.  OK, it抯 got a lot of letters, so we抣l only make you read it once or twice.  We call it PCOCC.

PCOCC ?aka PS Power SC - is a rare and unusual material, second only to pure silver in its conductivity.  It has just one single crystal that forms the entire length of a conductor!  Compare that with TPC copper or even pure OFC copper - which has literally thousands of crystals in the path of the electrons and these crystals form barriers to connectivity and unimpeded power flow.  Not so with single crystal.

Going against the grain
There are two key elements that determine a conductor抯 performance:

1. Purity of material (such as oxygen-free copper). For as long as we抳e made cables, we抳e had that one covered.
2. The number of grain boundaries.  A grain boundary is the meeting point between two grains (or crystals) of metal.  Here抯 what we抳e discovered?/LI>

Grain boundaries tend to scatter and impede the flow of electrons and act as a non-linear resistance to the flow of electric current.  With fewer boundaries, the less the effect on an electric signal as it propagates from one end of the conductor to the other.
What we want is zero boundaries, and only PS Power SC (single crystal) continuous cast copper provides such performance.  Even silver, which is recognized as the best conductor of all the metals has a few grain boundaries.  Not so with PS Power SC.

Here抯 the coolest part
In the past, the only way to get the most bass impact was to go to lower gauge (thicker) conductors.  And that worked, but there was always a downside or two.

1. If we went too big, we got bass at the expense of treble extension.  So it was always a judgment call to get the best balance.  Worldwide sales certainly proved that we 搗oiced?the cable balance correctly.
2. Big fat cables are a pain in the patootie.  They cause components to move around.  They come out if you barely touch another nearby component.  They add clutter and they definitely are NOT user friendly.

Well guess what?  SC cables don抰 have to be as big as the older technology cables.  We wish we could give you the scientific explanation.  But we can抰.  At least not exactly?BR>
What we think is that without all the grain (crystal) boundaries, the current flow is greatly enhanced, kinda like using larger gauge conductors to achieve the same results.  Only now, with PS Power SC technology, we get fluid mids, and delicate highs to go with truly authoritative bass.

All this improvement AND with a smaller gauge cable - eight gauge in the Statement SC vs. 6 gauge in the older xStream Statement version.

OK, we admit it.  We didn抰 expect it, but who抯 gonna complain?

And to top it all off, we ended up with an absolute reference power cable that you can actually bend! 
What抯 the bottom line, you ask?

PS Power SC simply lets through more of what we want to feed our equipment than we ever thought possible.  The performance benefits are immediately appreciated from the moment you connect a Statement SC to any piece of electronics in your audio video system:

• Increased depth, bass, and richness of the sonic tapestry
• Cleaner and lower noise soundstage
• Breathtaking openness
• More lively presentation
• A simply more involving experience
• Video looks more three dimensional with better blacks because of the lowered noise floor.

Almost unobtainium
In 1985, a method for the extrusion of a grain free copper wire was developed by Professor Ohno in Japan.  Known as The Ohno Continuous Casting Method, molten copper is forced out of the mold and very slowly draws the grain down the conductor's length, creating a 'single grain structure'. 

Unfortunately, there抯 only one machine in the world that creates single crystal copper. It抯 owned by Furukawa metals in Japan.  This one machine is so specialized that they can only run it every other day.  The casting machine needs an entire day to cool down and be prepared for the next run.

This rare single crystal (SC) copper is nearly ten times more expensive than OFC.  Not surprisingly, it is difficult to purchase. And, as you might imagine, there are relatively small quantities made at any one time.

PS Power has secured futures on this material.  So we can build our power and audio cables with only the finest of materials, directly cast out of this single machine in Japan. 

Here抯 the inside story
The cutaway illustration of the Statement抯 inside shows a wealth of conductors, shields and geometric perfection.

The original Statements were 6 gauge OFC copper.  The new SC version is 8 gauge PCOCC (ok, that抯 the last time you抣l see those initials, promise).  This all new metallurgy allows these new SC versions to be lighter, more flexible and sound more powerful, open and alive.  Reducing the wire gauge of the Statements was one of our goals and the use of SC (single crystal) technology made it possible.

The Statement SC has multiple shields and each of the shields lowers noise. The individual shields make sure that noise from within the power cable as well as noise from outside the power cable never see each other.  The Statement SC is one of the quietest power cables in the world.

But shielding can only do so much.  In the SC series, the AC gets cleaner as it passes through the power cable.  The outer jacket of the PS Power SC acts as a filter to actually clean the AC power as it is delivered to your equipment!  Ferrite, a magnetic material that acts as a noise filter, is impregnated in the Statement抯 outer jacket.  So the cable cleans as it delivers unrestricted power to your equipment.

Despite the heavy SC copper content, ferrite jacket and multiple shields, the Statement SC cables are flexible enough to be used in any situation.  This is truly a state of the art power cable by anyone抯 standards.
Making a Statement
When there抯 no room for compromise you have to choose a PS Power Statement SC to deliver the power your equipment requires.  Whether that equipment is a preamplifier, a power amplifier, a DVD player, projector or a surround processor, the Statement SC simply and effectively delivers AC power in the cleanest most efficient manner of any power cable on the planet.

The SC series of power cables is not a step-up from other aftermarket power cables. By raising the bar so high, the SC power cables have created an entirely new class of power delivery.  From the connectors to the conductors to the outer jacket to the geometry of the cable itself: every single facet of these power cables represents new thinking and new technologies. 

From a performance standpoint the Statement SC抯 provide a remarkable improvement over any other after-market power cord we have ever auditioned, regardless of price.

The difference is in the details
To build the world抯 best power cables, we started from scratch and worked our way up.
What was the first step?  Redesign the connectors themselves.

PS Power SC power cables use our custom made male and female connectors.  In contrast, every aftermarket high-end power cord uses an off-the-shelf male and female AC power connector.  These off-the-shelf connectors find their way on cables as low as $50 to as high as many thousands of dollars.

Some folks (who don抰 yet know better) actually consider these old technology connectors to be state-of-the-art.  But, they are not.  Here抯 why?BR>
Take a look at the way the plug and IEC connectors are made in this photo of a 'state-of-the-art' hospital grade aftermarket connector used on many high end power cords.
 
Note the plug prong is a three-piece affair made from a piece of stamped metal (the IEC is constructed in the same manner).  The three parts are the prong, the clamp cover and the screw.  The prong and clamp are made from brass and the screw is constructed of steel.

To build a high performance power cord with these off-the-shelf connectors, you have to accept a compromised connection scheme: basically you insert the conductor into the clamp and tighten; the steel screw is used to hold the conductor in place.

The problems with this style of build:

• Multiple pieces are prone to oxidation, corrosion and poor fit
• Using a steel screw to pressure copper against the brass prong is not the best connection in the world
• It holds little promise of longevity.

Created male and female
To solve the problems of longevity, connectivity and loss of surface area, PS engineering went to work designing an entirely new male and female connector from the ground up.

To address the issue of multiple pieces of stamped and dissimilar metals in the actual prong itself, we machined our prongs out of a solid block of high copper content brass, and then polished both the female and male prongs ?and finally nickel plated all surfaces and polished them again.

By machining the new prongs from a solid block of material, we were also able to resolve the dilemma of the unnecessary hole in the mating prong as well as the dissimilar metal problem.

Even the female side of the PS power cable is revolutionary as well.  So strong is the gripping force of the PS Power IEC female end that you can literally dangle a piece of equipment from the PS power cable without it falling!  Try that with another power cable!

Hot and Cold
Once we had a single piece of machined metal with an appropriately sized hole to receive the cable抯 conductor, it was time to do a better job of attaching the conductor to the connector.

Traditional off-the-shelf stock power cords simply squeeze the brass end over the wire.  Most 揾igh-end?power cables use a tightened steel screw to hold the conductor against the prong.  Both of these methods are prone to oxidation and corrosion AND loss of connectivity due to repeated twisting of the connector.

The PS Power Punch and SC series each employs two forms of welding to fuse the conductor to the machined prong: cold and hot.
Cold welding exerts thousands of pounds of pressure supplied through the force of a  hydraulic press to squeeze the two metals together such that the metal structure of the two pieces actually fuse together.

To further insure a perfect connection, we then solder each of the machined prongs with high silver content solder in a hot welding technique that creates the perfect bond.

Hermetically sealed for protection
To address the issue of long term conductivity and eliminate problems such as oxidation, PS Power engineers designed an outer shell that is molded over the machined, cold and hot welded connectors.

This molding process, which also incorporates a built in strain relief, keeps the outer elements away from the all-important fusion of the prongs to the conductors.

The custom connectors on the PS Power Punch and SC alone will revolutionize the category and set new standards for state-of-the-art status in power delivery systems.

A shield that cleans?
Each SC power cable has multiple shields to keep the noise from the powerline contained and unwanted radiation from entering the power stream.

But we didn抰 stop at just shielding.  PS Power SCs actually clean the noise from the AC line while it is powering your equipment.

Every SC power cord employs magnetically active ferrite powder evenly distributed along the entire length of the outer jacket. This produces the world抯 first distributed inductive shield that actively cleans some of the high frequency noise on the AC line itself!

This is a major achievement in the art of power cable delivery, resulting in the lowest noise floor of any power cord we know of.  And that means a richer listening and/or viewing experience to you!

Why didn抰 I think of that?
One of the most useful innovations with the xStream SC and Power Punch cables is a removable ground pin. The ground pin on a power cable is there to tie the ground of the AC receptacle to your equipment. However, in some cases, this ground pin can cause a ground loop and cause hum and buzz in your system.

To neutralize the ground loop that creates hum and buzz in your system, audio and theater enthusiasts have traditionally used what is known as a 揷heater plug?.  A cheater plug is an inexpensive three-prong to two-prong adapter.

Unfortunately, this adapter completely ruins many of the benefits of a high performance power cable like the SC or Power Punch.

PS engineers invented a better way: a screw-in ground pin.  Instead of using a cheesy cheater plug and running all the benefits of the SC or Power Punch抯 machined connectors, you simply unscrew the ground pin and voila!  No more buzz.

Putting it all together
Machined prongs hewn from a solid billet of material

• Cold and hot welding
• Over-molded and hermetically sealed connectors
• Multiple shields
• Solid core single crystal copper
• Conductive PVC shield
• Multiple braided and foil outer shields

The PS Power SC series will open your eyes and your ears with a level of improvement you probably never dreamed of.

It's time to get the power delivery system in your home audio/video system right.  Remember, if you don't get the power delivered to your equipment properly, then you抣l never take advantage of your investment in fine equipment.

It's time to maximize your system and get connected with a Real Power SolutionTM.

xStream Plus SC More Info

About as close as it gets
It抯 easy to say a product is state-of-the-art.  It抯 far more difficult to create a product that actually IS state-of-the-art like the Statement SC and perhaps even tougher to create the next best ?the Plus SC.  Not really a step-down from the Statement, but more like 揳bout as close as it gets?when compared to our very best.
