If it’s working well but it could be even better, this will help it along very nicely … with more ambiance and detail and, most importantly, a better sense of timing to the music. I use mine in conjunction with audiophile mains leads (Nordost and Furutech), power conditioning units (Nordost, ISOL8), etc where you think it might have less opportunity to improve things, but it certainly works for me. I use two and am thinking about more. Another iFi power conditioning winner, along with the excellent DC iPurifier 2 (of which I have 6 or 7)!
Tasting pure, clean water only leaves you thirsty for more. The AC iPurifier has the same effect on your ears.
Plug in. Play and hear the difference.
You won’t believe your ears.
When you listen to music there’s a lot of background noise going on. Some noise cannot be missed but there’s also some that is not immediately obvious until it has gone. It mainly comes from your power supply and interference from other devices.
Bring the AC iPurifier into your set-up and you’ll notice the difference instantly.
Music you once thought was clear takes on a new life, filtering out noise you never knew was there and leaving you with pure, undiluted sound.
Hydrate your hearing.
You deserve the best in home audio, and the AC iPurifier does just that.
Drink in crystal clear music once more.
The tech spec.
The AC iPurifier draws from French military engineering and includes:
- Active Noise Cancellation To cancel all incoming mains noise
With EU and USA 3-pin versions. It can handle 100 volts to 240 volts. The UK version comes with adapter to EU version.
And with a chassis made from polyurethane plastic, the AC iPurifier is not only powerful, it’s tough too.
Cleans up noisy mains supplies.
It ACTIVELY cancels noise. The AC iPurifier cancels far more noise across the frequency range than other passive products.
Active filtration is MUCH better at -40dB and effective across the frequency range as this graph shows.
A passive purifier filters only in the very top-end of the frequency range.
By generating a signal identical to the noise signal but in the exact opposite phase, our Active Noise Cancellation® (ANC) actively cancels all incoming noise!
Modern audio systems have a plethora of mains plugs. Each of these add unwanted noise issues and pollute the local mains supply.
You can insert into the AC mains wall outlet that supplies the audio system OR insert into the mains extension block for the audio system.
The design of the AC iPurifier is such that it is even more effective if several are used to ‘contain’ the same type of noisy sources.
Try in different locations to discover which has offers the most improved sonics.
Wireless Purification System.
This reduces noise without audible side effects. It does not hinder dynamics.
Intelligent Ground Connection.
It only actively provides an earth/ground if your system needs one. It will not create a ground loop.
Smart Polarity and Earth Connection.
Insert into your system to check polarity.
Red - incorrect. Green - good to go.
Saves your system!
If it detects a power surge it will automatically cut off, protecting your valuable and highly sensitive equipment from harm.
iFi AC iPurifier review: goodbye, power noise
In regards to noise reduction, the iFi AC iPurifier works as advertised – it removes a lot of noise and makes it more bearable. It is also incredibly easy to operate and fits any power plug (in my case it’s an EU plug, but there is the USA plug also available).
There are multiple factors that can lead to electrical noise in a system, but the AC iPurifier is in fact a quick and effective solution that is not even that expensive. With its ~$100 price tag, it is affordable and can be considered an investment to surely improve the quality of the sound. Contrary to other things (i.e. cables) that may be considered pure snake oil by some, this works.
AC iPurifier – Inexpensive and it has active noise cancellation built in!
“It is user-friendly. Just insert into the audio mains extension block. It’s unique in the marketplace.This thing is actually worth giving it a try!”
AC iPurifier – insert, start music and you’re done!
“The overall sound is more harmonious in every respect – in dynamics, in transparency, in naturalness. The AC iPurifier seems to have a positive effect. The background vocalists are relaxed and in total you can hear pleasure again instead of an analytical search for missing sounds.”
It Cleans The Electrons Of Your Power Outlet!
You plug it to the AC mains wall outlet that supplies the audio system or into the mains extension block for the audio system separating analogue digital equipment, and it automatically takes samples of the current from your socket to perform an optimal filtering.
Through the ANC technology (Active Noise Cancellation) and WPS (Wireless Purification System), the AC iPurifier calculates and sends a signal back to the socket that cancels the perceived noises. On the other hand, it protects the equipment against voltage surges, detects lack of ground in the system and if the polarity is correct. And if that were not enough, it has an intelligent ground connection (Intelligent Earth) that you can use to connect the ground of all your audio equipment, but it only works if necessary, further avoiding more ground loops.
