About the iFi Audio iPurifier3

Improve your listening experience

I listen to a lot of music at my desk. And just like with my living room system, I'm always interested in simple tweaks that can improve my listening experience. That's why I'm intrigued by the iFi iPurifier3. This compact, solidly built device plugs into your computer's USB port and instantly reduces noise and jitter that can color what you're hearing.

Improve your listening experience

I listen to a lot of music at my desk. And just like with my living room system, I'm always interested in simple tweaks that can improve my listening experience. That's why I'm intrigued by the iFi iPurifier3. This compact, solidly built device plugs into your computer's USB port and instantly reduces noise and jitter that can color what you're hearing.

How does it work?

The iPurifier3 uses active noise cancellation to reduce noise that's generated by your computer's circuitry. It also "reclocks" your source's digital audio stream, providing a clean, jitter-free path for your music. 

Use it in conjunction with an outboard DAC (digital-to-analog converter) to get the best sound possible from music, YouTube® streams, and video games. With no buttons to press — and no set up required — the iPurifier3 is truly "plug and play."

Who is iFi Audio?

iFi is an award-winning British audio company that specializes in sound-improving solutions. Their gear is packed with sophisticated circuitry that helps you get the most out of your listening experience.

Product Research

Features

Overview: The iFi Audio iPurifier 3 is a USB filter that eliminates noise, giving you a better computer audio experience. The iPurifier 3 is made with simply plugs into the USB chain, either through the USB A or USB B port, with adapters for USB-C and Micro USB. It uses several iFi technologies, including Active Noise Cancellation and second-generation REclock/REgenerate/REbalance. The input port is compatible with USB 3.0 and USB 2.0, while the output port is USB 2.0 High Speed compliant, supporting all formats, including future PCM, DSD, and DXD formats. The iPurifier 3 is 3/4" wide, 3/4" high, and 2-3/4" long, and weighs only 2 ounces.

Construction: The iPurifier 3 is built for performance, with solid aluminum connectors and a white armored case. Inside, it utilizes OS-CON capacitors for excellent noise reduction, Tantalum capacitors for stability and efficiency, and Vishay MELF resistors for better accuracy and reliability. Gold-plated copper-alloy shielding isolates devices and cables from EMI and RFI interference.

Active Noise Cancellation: The iPurifier 3 uses military-grade Active Noise Cancellation (ANC) to reduce noise in your audio system by 40dB or 100x, compared to a common noise filter. Similar to ANC in headphones, the iPurifier 3 detects unwanted noise and introduces a second but opposite sound wave that cancels out the noise, particularly in the lower frequencies. The device also utilizes passive noise cancellation through insulating filters which eliminate middle and high frequency noise.

REclock, REgenerate, REbalance2: iFi Audio's state-of-the-art REclock, REgenerate, REbalance2 technology corrects any errors that may have occurred in the transmission of the USB audio and power streams. In the REclock and REgenerate phase, the USB signal is repeated so the frame and packet noise and jitter can be removed, restoring the integrity of the USB signal. The REbalance phase corrects the USB signal balance and impedance mismatch to remove distortion caused by DC offset.
