Military radar tech
for audio

1uV of audio noise,
astoundingly quiet

Dynamic noise suppression
circuitry on Input and Output

For ‘centre negative’

The central characteristic of iFi is in pursuit of the zenith in audio performance: it leaves no stone unturned. Well, the all new iPOWER is an exemplary example of this. Despite the fact that the iFi Ultra-Low Noise AC/DC adapter was exceptionally quiet and elevated the iUSB and iPhono to punch way beyond their respective categories, the all new iPower is even quieter, up to 10x quieter in fact.

What is it?

Brand new audiophile-standard DC-power supply:

In 5V, 9V, 12V and even 15V versions.


Which products is it aimed at?

Virtually any DC powered device.

Just check the correct voltage (5V/9V/12V/15V).

Check the correct polarity setup (see ‘Polarity Inverter’ below)

Ensure the current output is sufficient, then plug in and enjoy.

Advanced DC power design – the best has just been bettered.

Three years ago, iFi’s Ultra-Low Noise AC/DC power adapter set the way and underpinned the whole iFi range from the iUSB to the iPhono leading to their loyal following.

Well, not to rest on its laurels, iFi now has a completely new ‘ground-up’ DC powered supply.

Active Noise Cancellation+® drawn from military radar technology


Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation+ ® (ANC+®) audio power system. It is so good ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range.


An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an onboard system to cancel out the enemy radar signal.

By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+® is the perfect ‘antidote’ for power supply noise, the bane of USB audio.


With ANC+® the power line is filtered for audio band and RF noise. The measured noise floor of 1uV (0.000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of.

What audio noise floor?


Measured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi’s very own Ultra-Low Noise AC/DC adapter was in a class of its own at 10uV. Compared to a typical audiophile Linear Power Supply which measured at 20uV, it is demonstrably clear AMR/iFi power supply technology is unparalleled.


12-Element Output Array/6-Element Input Array

Shaping the face of technology, AMR/iFi not only pushes the boundaries of audio design, but power design too. After all, electricity is the ‘fuel’ behind the audio signal.

There are two separate, but similar ‘Array Technologies’ in the iPOWER:

12-Element Output Array – is for addressing noise on the output (at the DC barrel) end.
6-Element Input Array – is for dealing with noise at the input (at the 2-pin mains) end.

What this means is that any noise is contained and neutralised with the iPOWER to halt it from contaminating the local mains or audio system. iFi is one of a handful of companies that manufacture ‘battery quiet’ DC power supplies. Just like hybrid technology in cars, both have come a long way in a short space of time and are gaining wider acceptance.

Polarity Inverter Adapter for ‘centre negative’ audio products


At iFi, we like to think comprehensively and while the majority of home and pro audio products have a ‘centre positive’ DC power connector type, if your product such as a guitar pedal or a Sony Discman has a ‘centre negative’ instead of ‘centre positive’ pin, it is important to use the iFi power inverter. If you are unsure of the DC polarity of your product, please check with your vendor. For equipment using a DC power connection, it is common practice to include protection circuitry against over-voltage/reverse polarity, but not every manufacturer will have applied this. Always check first as AMR/iFi is not responsible for incorrect use or damage arising from use of the iPower.

Can be used globally; world-wide suitability


AMR/iFi understands and appreciates that today, being portable and user-friendly is paramount. So the iPower is light, convenient and above all, easy to travel with and work in any country in the world. It comes in 5V, 9V ,12V and 15V versions for all manners of DC powered devices and a set of interchangeable pins to span the globe: for USA/UK/EU/AUS electrical outlets. Performance and portability personified.

In summary, all the technology behind the iPower would count for little if it was not audible. Well, it is both. With the all-new iPower, the noise floor is virtually inaudible and the all-important level of refinement (whether listening to an analogue or digital source) has been amplified several notches.

Best of all, all existing iFi-powered devices all benefit, and in the different DC-power versions, the iPower now compliments non-iFi DC-powered products too. So all can enjoy the “sound of iFi.”

Got Raspberry Pi or similar? Then use the iPOWER 5v

iDSD Nano LE, iDefender 3.0 & iPower 5v all put to the test!

“I wonder what will come of all this. Very interesting…….we are going to test it in the way that so far no one has tested it……..I listened to this immediately after the release, immediately after the first IFI Audio products in Poland. ”

Kalman of Stereophile enjoying the iPower!


“In the case of the miniDSP DAC, the iPower fulfilled iFi’s promise. When I switched over from the stock supply, the DAC didn’t seem quieter when there was no audio signal, but that’s not the real test. Recordings with open, ambient soundstages sounded cleaner, and both instrumental and vocal music was more distinct. This was no major change that struck me every time I listened, but it did make all of my listening much more relaxing—perhaps because, subliminally, it required less effort to attend to individual sounds, particularly those far back on the soundstage”

Thanks Kalman Rubinson and!

Dr.Pi introduces the iPower 5V to the Raspberry Pi!


“If there is one major question that I get all the time is how to improve the Raspberry Pi streamer performance. The most obvious choice is to upgrade the power supply…….A great alternative is the iPower, a sophisticated ultra low noise SMPS from British manufacturer iFi Audio…….Back when I first tested the linear power supply against the run of the mill SMPS I was using in the first days the difference in sound was noticeable so iFi has obviously performed some magic with the iPower. Highly recommended!”

Thanks Panagiotis Karavitis aka, Dr.Pi! provides a press review of the iPower!


“Among their many products we have finally found what could be the solution to the many problems of our age-old power pedals and crank-gear multi-effect. There are many power supplies on the market stabilized, but wanting to power a single pedal or a multi-effect pedals without fear hums classical or electric shock? iFi Audio has thought of iPower , a power supply (available in versions 5V, 9V, 12V and 15V) which promises to be as quiet and stable on the market. iPower can replace any power supply for pedals or sound cards or other audio devices. Its internal technology is rather complex but, without going into much detail, we can say that contains a cancellation circuit activates the electric noise derived from military technology and an array of 12 elements that filter the noise about 1000 times more than a normal power supply .The power supply can be used in any area, thanks to the sockets adaptable, and can also be used with center-negative products, thanks to an ‘inverter’ included.”

iPower: “The iFi feeding the sound of the piano became fuller, the momentum grew and here was again the better display of texture on. In this incredibly beautiful recording is also a lot of ‘ambient’ sound, both in the foreground as far back, and with the iFi food was all to follow a lot better, which the entire display was much richer. This is, for the five decades that cost the food, an absolute no-brainer. ”

Richardo enjoys the iPower!

“so I asked to try one of the iFi new iPower products on the iFi iTube…If you have an iFi iTube, do not take my words, go and try one, the difference is big, really big, at least in my system, a lot more clear, in all areas, and it’s only a power supply, but for 50 euros, is the best 50 euros I have spent lately.”

Thanks Richardo!

Diminuitive iPhono+iPower ‘David’ slays ‘Goliaths’ and then some

AudioFun on Audiogon is sure having plenty of his moniker when he paired the iPhono+iPower against some serious US$10k phonos (including its bigger sibling, the AMR PH-77).

‘I know some of you will dismiss this next statement as the rantings of a mad man but, if you are looking to spend up to $9k on a phono stage you really should audition this unit (with the newer power supply) and fully run in (say at least 300 hours to be safe).’

Many thanks AudioFun and keep on enjoying the tunes!

The iPower from Teta Mona’s perspective!

To celebrate the release of the new iFi accessory, iPower, Teta Mona a musician and vocalist from Italy has kindly submitted to us a few images of the iPower with her setup! We recently met at this years High-End event in Munich along with Pro Audio Italia when she twisted our arms and bagged an iPower to try with her equipment such as a guitar’s foot pedal. Teta reports good results using the 9v version of the iPower!

Her equip in these photo’s are; flanger pedal, iPower 9v / 1a, Epiphone sheraton ii and 1960s rogers drums.

Although the iPower is an audiophile-standard DC product its aimed for everyone in the audio market….this includes musicians!

Grazie Teta Mona and Pro Audio Italia (iFi: Italy)!
