The SilentPower USB iPurifier Pro is a high-performance USB noise filter that upgrades USB audio by combining galvanic isolation, ANC3 Active Noise Cancellation, and IsoGround ground-loop management. It helps reduce EMI/RFI and stray currents that can mask detail and degrade clarity in DACs and USB-powered devices. With USB-C or USB-B 3.0 inputs, dual USB-A 3.0 outputs (Power & Data + Power Only), and up to 10Gbps support, it’s built for modern high-resolution playback. Add a clean 5V external power supply via USB-C to bypass noisy bus power and further improve performance.

Features & Specs
Galvanic Isolation
Electrically separates the USB input and output stages to prevent noisy source devices and connected peripherals from injecting stray currents that can increase jitter and haze.
ANC3 Active Noise Cancellation
Actively reduces high-frequency interference (EMI/RFI) on the USB power line, helping lower the noise floor and preserve micro-detail and spatial cues.
IsoGround Ground Management
Intelligently manages earth connections to reduce ground-loop behavior that can cause hum, buzz, or inconsistent sonic performance across multi-device systems.
External 5V USB-C Power Input
Enables you to supply clean external power (5V/3A max per manual), effectively bypassing noisy USB bus power—especially beneficial for USB-powered DACs and devices.
Two Purpose-Built USB Outputs
Provides a dedicated Power & Data output for your DAC plus a separate Power Only output for devices that need clean USB power without a data link.
High-Speed USB Support
Designed for modern use with up to 10Gbps capability to help maintain broad compatibility without sacrificing responsiveness or stability in demanding USB setups.

iFi Audio SilentPower USB iPurifier Pro
Silence USB noise and elevate your audio experience with the USB iPurifier Pro — the all-in-one successor to iFi Audio’s most sought-after innovations. Merging the galvanic isolation of the iGalvanic3.0, the ANC technology of the iSilencer, and the ground control of the iDefender, this compact powerhouse eliminates jitter, EMI/RFI interference, and ground loops. Designed for audiophiles seeking pure, uncolored sound, the USB iPurifier Pro ensures flawless data transfer at 10Gbps, supports external low-noise power, and is optimized to enhance every element of your USB audio chain. Whether streaming high-res music or refining your home studio setup, this plug-and-play device delivers clean, uninterrupted audio fidelity.
What It’s Good At
Lowering the noise floor for clearer detail, tighter imaging, and improved separation
Blocking stray currents and interference via galvanic isolation for cleaner USB audio
Reducing EMI/RFI on USB power with ANC3 Active Noise Cancellation technology
Taming ground-loop issues using IsoGround intelligent earth-connection management
Upgrading USB-powered DAC performance by enabling clean 5V external power input
Maintaining high-speed compatibility with up to 10Gbps data transfer support
Key Features List
All-in-One USB Noise Solution: Merges galvanic isolation, noise cancellation, and ground loop elimination into a single device.
True Galvanic Isolation: Blocks noise-causing stray currents without affecting signal flow or USB data integrity.
Advanced Active Noise Cancellation: Cancels EMI/RFI interference for dramatically cleaner USB power delivery.
External Low-Noise Power Option: USB-C input allows clean external 5V power, cutting off noisy source power entirely.
10Gbps USB 3.2 Compatibility: Ensures flawless playback of ultra high-res audio files and full-speed device functionality.
Q&A Section
Q: What exactly does the USB iPurifier Pro do? A: It removes USB noise caused by EMI/RFI, stray currents, and ground loops, delivering cleaner audio from your USB devices.
Q: How is this different from the iGalvanic3.0? A: The iPurifier Pro includes galvanic isolation like the iGalvanic3.0 but also adds Active Noise Cancellation and IsoGround grounding control, making it a 3-in-1 solution.
Q: Can I use it with my DAC or streamer? A: Yes, it works perfectly with any USB-based DAC, streamer, or audio interface to improve signal quality.
Q: Does it slow down USB speeds? A: Not at all — it supports USB 3.2 Gen 2 with up to 10Gbps transfer, ensuring no speed compromises.
Q: What is the benefit of the external power input? A: You can bypass noisy source power by supplying clean 5V power via the USB-C port, which improves overall performance.
Q: What if I need to add ground instead of removing it? A: The unit includes a 4mm grounding port compatible with iFi's Groundhog+ for manual grounding options.
Q: Is it difficult to install? A: No, it’s plug-and-play — just connect it between your source and DAC or USB device.
Q: Can I use it with USB-powered devices? A: Absolutely — it even improves power delivery for bus-powered DACs or headphone amps.
