Loving your computer audio set-up but got annoying system and power noise?

Let the iPurifier3 improve your USB audio playback experience.

Gremlins beware

Computer audio often comes with annoying noise and jitter.

The iPurifier3 is for anyone into USB audio who regularly battles with these irritating audio gremlins.

Never fear, let the iPurifier3 be your system’s white knight.

The white knight

The third generation and slightly larger reincarnation of the iPurifier measures just 69 x 19 x 20mm in its new, dashing white armour. Both Type A and B are available.

It uses iFi Active Noise Cancellation2 tech to decrease noise by 100x or -40dB in comparison to the common noise filter.

REclock, REgenerate, REbalance®

Our state-of-the-art REclock, REgenarate and REbalance2® technology will get your audio back on track.

Put simply, it actively ‘restores’ the USB audio+power streams which eliminates jitter and ensures smooth passage for your music. REbalance® actually removes distortion caused by DC offset.

Dashing. Durable.

The iPurifier3 is set up for all future PCM, DSD and DXD formats. And it’s not just better looking on the outside, it’s been improved on the inside with updated components. No need to worry about upgrading for years to come.

It will improve your USB audio playback experience faster than you can say King Arthur and the Round Table.

The good news is that it is ready for all present and all future PCM, DSD and DXD files without restriction. Your music is safe, sound and future-proofed.

Enjoy the silence! Our Active Noise Cancellation II® (ANC II) tech means that measured noise drops by 100x or 40dB in comparison to the common noise filter.

Tantalum capacitors are another example of the top-notch components we prefer. These polarised electrolytic capacitors have superior frequency and stability characteristics, giving them a super high volumetric efficiency.

iFi always uses the best components possible. These OS-CON™ capacitors provide excellent noise reduction and have a long life span. They are not often found in products costing <US$1000.

REclock2, REgenerate2, REbalance2® – cleaner, clearer music. The 2nd generation of this technology creates an all new signal, eliminates computer jitter and removes noise contamination to restore a ‘balanced’ signal.

This excellent copper-alloy EMI shielding isolates devices and cables to block radio frequency electromagnetic radiation.

Vishay MELF resistors – complex, costly but superior.

These metal electrode leadless face resistors have excellent accuracy, stability, reliability, and pulse load capability. They provide optimal power rating and pulse load capability. Nothing else comes close.

Reviews

It’s ‘i-fi’ and not iffy at all!

“…considering the modest price I consider it to be a bargain and a very worthwhile addition to my hifi.”

USB Audio

USB audio is a digital audio connection used to send digital music from your computer to a digital to analogue converter (DAC). Usually computer manufacturers spend most of the overall budget on the processors and screen, leaving minimal budget for the built-in DAC and audio outputs.

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.

Common Noise Filter

The common noise filter cuts out most noise gremlins found in typical audio systems such as RFI/EMI.

File formats

MP3 – this is the most popular format, every device in the world can use it.

DSD – Direct Stream Digital is a very high-quality audio format, better than CD quality. The higher the number (sample rate), the better the recording – DSD64, 128, 256, 512 and 1024.

PCM – Pulse Code Modulation is the most common format for CDs and DVDs.

DXD – Digital eXtreme Definition is a very high-quality PCM format. It was developed to edit hi-res (high quality) recordings recorded in DSD.

Volumetric Efficiency

In electronics, volumetric efficiency quantifies the performance of some electronic function per unit volume, usually in as small a space as possible.

Pulse Load

A ‘load’ refers to a current drain that is applied to a battery. For example, charging the flash in a camera. The term ‘Pulse Load’ indicates that the load is automatically applied for a specific period of time, then disconnected without user intervention.

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.
