iFi audio iPower Plug
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.

Ifi Audio iPower Plug

Power up!

The iPower use Active Noise Cancellation+ to cancel all incoming EMI or RFI noise.

It is at least 10x quieter than previous iFi power adapters, 20x quieter than audiophile linear power supplies and 1000x quieter than standard SMPS wall adapters.

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.

You’ve got the power

Add the iPower into your system and you’ll notice music come back to life. It can add in detail originally lost through conventional power supplies.

Get your power back with the iFi iPower.

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.

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.

Reviews

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.
