It works with virtually any DC powered device and comes in 5, 9, 12 and 15 volts.
Just check the correct voltage and away you go. Clean, audiophile grade power.
When is a plug no ordinary plug? When it’s an iFi iPower.
Use an iPower to replace your regular power supply for clean, noise pollution free power.
Power hungry
Got underlying noise in your system you can’t explain?
It could be as simple as your power supply.
Upgrade to the iFi iPower to feed your system’s circuits with clean, audiophile grade power and address issues at both the output and input stages.
iPower for LED lights
Photography? No way. iPower can also solve my flickering LED light problem?
Yes, a constant current and voltage power supply like iPowerX will ensure that the current supplied to your LED system will remain stable, no matter the fluctuations of the AC power in your wall socket.
It can be used all over the world as it comes with pins for the USA, United Kingdom, Europe and Australasia.
Quiet! Active Noise Cancellation+® (ANC+) at work!
Exceptionally quiet power. The measured noise floor is 100x quieter than the common noise filter.

Sounds great for the money!
Very good lineair power supply to use in your audio and/or network chain and therefor very low noise floor, great effect on portable DAC and “last mile” network switches

Superb
I have been suffering from terrible noise on my Cambridge Soundworks PC speakers for years. This got a lot worse recently when I started using Powerline networking. This was an extreme crackling noise. The iFi psu has completely solved the problem and thus improved my quality of life no end! I can’t recommend this product enough.

Noise killing PSU
I bought this to eliminate the noise generated from a nobsound ns-08e mini tube headphone amplifier’s power supply ac/dc adaptor and it just did that. My only concern was the cost of the total product which is almost the same as the affordable amplifier.
Well done IFI! Goes to show you how much care is needed when building high quality audiophile equipment. I think the cost of the PSU can go down if the buyer could discard the multiple adaptor and cable accessories that come bundled with it especially when you might most certainly buy another one e.g. pre amplifier or digital to analogue converter.

Actually hear a difference
I’ll give it a 5% improvement for my Amazon Cube with Amazon Music HD.

Improvement over the SMS unit supplied with the DAC
Improved the upon the soundstage that came using the supplied SMS. Only minor problem was the SMS used a 3mm diameter male plug. Which meant having to source a 2.5mm to 3mm diameter connector, as the range supplied with the unit did not cover this. Eventually found a source else it was £50. down the drain.

Oh bleep! I expected nothing but it works
I actually used it for a different application to most, I bough it for a Sony PSHX500 turntable. In fact I really do not believe it can do much different to most dacs, as dacs and streamers have already circuit filters but well in the turntable sector one of the first upgrades are linear power supply, yet this not exactly such but neither is my turntable a Rega Planar 3. I just hoped a better switching power supply would mean better pitch stability. I tried it thinking sure I will return it.

EMI (Electromagnetic Interference)
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.
RFI (Radio-frequency interference)
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.
Switch Mode Power Supplies (SMPS)
A switched-mode power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. It transfers power from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics.
Switch-mode power supplies are widely used because of the advantages they offer in terms of size, weight, cost, efficiency and overall performance. They are in themselves noisy and were not designed with audio in mind.
Active Noise Cancellation
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.
