SilentPower by iFi USB iPurifier PRO

The USB iPurifier Pro is the next evolution in USB audio purification - eliminating noise at the source with galvanic isolation, Active Noise Cancellation (ANC), and IsoGround technology. Combining the DNA of three iFi icons (iSilencer, iDefender, and iGalvanic), it removes the jitter, hum, and electrical interference that degrade sound quality. The result: cleaner, richer, and more immersive audio from your USB DAC.
By physically isolating power and data lines, the iPurifier Pro blocks ground loops and noise transmission from your source to your DAC. Its internal ANC system, inspired by radar technology, cancels interference by generating an inverse signal - cutting noise by 100x. It features dual USB-A outputs (power & data, power only), a USB-C port for clean external power input, and a grounding port for complex systems.
With support for blazing-fast 10Gbps USB 3.0, the iPurifier Pro ensures flawless high-resolution audio playback, no matter the file size or format. Whether you’re running a minimal setup or a full desktop rig, this compact unit gives you the sonic upgrade you’ve been chasing.
Engineered for Purity and Power.

Galvanic Isolation for Pristine Audio
At the heart of the iPurifier Pro is galvanic isolation, which physically separates the USB data lines from the power source. This breaks the electrical connection between noisy computers and your DAC, preventing stray currents from corrupting your signal. The result is a cleaner, more stable audio experience with improved dynamics and detail.

Next-Gen Active Noise Cancellation (ANC3)
Building on military-grade principles, the integrated ANC3 technology identifies and cancels electromagnetic interference by duplicating and inverting noise signals. This process reduces power line noise by up to 100 times (40dB), restoring clarity and silence to your listening environment without compromising speed or performance.

Break Free from Ground Loops
Ground loops are a common cause of hum and buzz in audio setups, especially those with multiple components. The iPurifier Pro features IsoGround technology, which intelligently breaks unnecessary ground paths. This eliminates hum at the source and ensures your system operates with clean, uninterrupted grounding.

External Power, Cleaner Results
While the iPurifier Pro can be powered directly from the USB source, the option to connect an external 5V power supply (such as iFi’s iPower2) unlocks even better performance. This bypasses noisy onboard power from your PC or streamer, providing ultra-clean energy for sensitive audio gear.

Dual Output Flexibility
Equipped with two USB-A 3.0 outputs—one for power and data, the other for power only—the iPurifier Pro gives you flexible connectivity. Whether you're powering a DAC, isolating a USB-powered device, or feeding a headphone amp, the outputs are purpose-built to reduce interference and improve signal quality.

Speed to Match the Silence
With 10Gbps USB 3.0 support, the iPurifier Pro delivers data speeds 20x faster than USB 2.0. This ensures zero bottlenecks for high-resolution audio playback and seamless transmission of even the largest files. It’s designed for modern audiophile systems that demand both silence and speed.
