Whatever your set-up, digital, analogue or both, the PowerStation will ensure your system receives super quiet mains.
The iFi PowerStation is for everyone who likes their audio interference free.
It comes in 4 variatons – UK, EU and AU with 6 individual sockets and USA/JAPAN with 8.
Put a stop to RFI or EMI noise and enjoy pain-free audio – all from one solid, snazzy dark anodised aluminium power block.
The PowerStation uses iFi’s Active Noise Cancelation II to ACTIVELY eliminates noise across the frequency range, even across the lower frequencies.
Each outlet has added passive filters to also eradicate noise from the very highest frequencies.
Each outlet is independently isolated in its own chamber to prevent cross-contamination, with the addition of vibration-damping EVA (ethylene-vinyl acetate).
We use PurCopper – a form of 99.9999 per cent pure OFHC (oxygen-free high-conductivity) continuous-cast copper – for its superior conductivity.
The PowerStation has inbuilt earth/ground and polarity detection.
No earth/ground can lead to annoying buzzes and hums – the scourge of audio.
We’ve added a 4mm banana socket to the PowerStation so a grounding cable can be used to create a ground/earth when one isn’t present.
Bingo, the sound is gone.
And the PowerStation is smart. The supplementary ground/earth connection will NOT introduce a ground loop EVEN if the system is already earthed.
More than one earth would also create a ground loop leading to more buzzing and humming and we don’t want that.
Polarity detection is vital if you don’t want to hamper the quality of your audio mains. With the PowerStation, this is built-in.
And never fear, max. 30,000A @ 1,000V/10uS surge protection is also here. If it detects a power surge or a mains short, the PowerStation will shut down, protecting your downstream equipment from peril.
The PowerStation doesn’t forget where it came from – the original AC iPurifier.
You can still use your original AC iPurifier with the PowerStation – use them to separate your digital and analogue devices for even less noise contamination.
This is an active not a passive product. As can be seen from the graph, it cancels far more noise across the frequency range than a passive product.
Active filtration is MUCH better in the lower frequencies, at -40dB. Passive filtration is only truly effective in the very top-end of the frequency range.

PurCopper – a form of 99.9999 per cent pure OFHC (oxygen-free high-conductivity) continuous-cast copper – is used extensively for its superior conductivity.
This includes 13 AWG, heavy-gauge internal wiring with multi-layered polymer insulation, solid PurCopper busbars and the conductive elements of the outlets themselves.
Our Wireless Purification System (WPS) is a complex circuit that reduces power line noise without audible or measured side-effects.
This is important because other solutions while attempting to curb noise, also hamper dynamics.
The LED indicators show Polarity and Earth detection. As usual, green is good, red signifies an issue.
There are four possible combinations and these can be found in a brief table in the User Manual. This tells you what the issue is and suggests how to remedy it.
The Over-voltage Surge Protection (OSP) is an auto detection and cut-off circuit.
Should it detect an excessive power surge or short in the mains electricity it will automatically cut off. If this issue persists, it will not reboot and will protect your equipment from harm.
It is effective to max. 30,000A @ 1,000V/10uS.
Our Intelligent Ground is a smart diagnostic tool.
It only actively provides an earth/ground connection if your system needs one. It will NOT create a ground loop even if the system is already earthed/grounded.
You can use AC iPurifiers in the PowerStation.
The more AC iPurifiers you use, the cleaner the overall power. If the AC iPurifier is placed in the middle of the PowerStation it will also act as a noise shield. Noise is reduced, isolated and confined to the respective left/right sections of the AC iPurifier.
Use it to separate your analogue and digital devices.
Based on military tech, our improved Active Noise Cancellation II® actively cancels all incoming noise.
It does this in a similar way to active noise-cancelling headphones – it generates a signal identical to that of the incoming electrical noise but in the opposite phase, actively cancelling it out. This is highly effective at removing low- and mid-frequency noise, while passive insulating filters deal with higher frequency interference. This combination is measurably more effective at eradicating noise corrupting the USB signal than devices relying solely on passive filtering.
It reduces the noise floor by > 40dB (> 100x).

I live in an old building from the 30s and the last refresh of the house electrical system was more than 50 years ago. At the same time, I have neighbors who like to indulge in all kinds of hobbies with pre-historic machines at the weekend. Especially when you have time to listen to music in peace, you can be sure that the loudspeakers will also make quiet whistling, crackling or crackling. So far, these disturbances have been fairly well suppressed to a tolerable level by line filters from the hardware store.
My last new acquisition (a streaming preamp) reacted so fussy to the network interference that listening was really no longer fun. So the alternative was: exchange the device, finally let the electrician lay the long planned separate line from the meter box – or try something completely different.
I had used a power supply from ifi for a problematic device some time ago, so I knew the brand and the basic idea of active interference compensation. At the time, however, I was not really convinced of the result. Nevertheless, I wanted to give ifi another chance, but I almost ordered the (expensive !!!) bar with the expectation that I would have to send it back.
In fact, the results in my application scenario are so convincing that I can only advise anyone with real network problems to try the part: Not only are all of the above-mentioned faults gone, but the system’s noise floor is also significantly lower. Incidentally, the active interference compensation affects the entire strip, but each socket has its own line filter. If you suspect that one of the system components is affecting the others on the network side (!), The bar is also worth trying.
Great power strip. I’m getting better sound from my ps audio amps and mytek Brooklyn dac +. Better than Furman and Furutech that I have used. Clean natural sound.
For years iFi audio has been known mainly for quality DACs, headphone amps and multiple handy accessories mainly associated with USB. In late July 2019 this operation’s portfolio expanded in the not exactly new but quite intriguing direction, which resulted in today’s arrival – iFi audio PowerStation. Enjoy!
iFi’s Audio’s AC iPurifier is a small, cylindrical, plug-in mini-power conditioner that plugs directly into AC outlets. Each AC iPurifier uses iFi’s distinctive Active Noise Cancellation circuitry. The AC iPurifier can detect polarity and/or earthing problems. There is also a 4mm banana-socket for adding supplemental earthing wires if desired. Finally, the AC iPurifier provides surge suppression to a maximum of 30,000A @ 1,000V/10ųS.
We were surprised by the nature and magnitude of the sonic improvements the PowerStation/AC iPurifiers wrought. Along with quieter backgrounds, the reviewer felt that, “really significant gains came in the form of deeper levels of textural and transient details.” He concluded that, “I recommend the iFi PowerStation and AC iPurifiers for the simple reason that they help unlock more music for less money than other competing power conditioners I have tried. You cannot say fairer than that.”
Putting together a high-quality hi-fi system, especially on a budget, is a daunting proposition.
There are so many variables at play, ranging from speakers, amps, sources, cables, not to mention your personal preferences.
After you read through all the reviews, get a gauge on what gear works for you, audition stuff, then plunk your hard-earned money down on a system that appeals to your ear, you may be ready to exhale and enjoy some music.
But wait! You’re not done. The quality of the power you get from the wall outlet also affects the quality of sound coming from your system. Many devices in the home, like televisions or even the power supplies used by your audio equipment, can introduce electrical noise…
Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.
Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.
A busbar is simply a conductor through which current flows.
EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.
In simple terms, polarity refers to the way a signal flows.
Audio signals generally flow one way, like DC current, and have positive polarity. Inverting the polarity can have a negative impact on sound and equipment.
Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.
Top tip: just don’t add water.
