SilentPower USB iPurifier Pro – Advanced USB Noise Elimination Module

The USB iPurifier Pro combines galvanic isolation, active noise cancellation, and IsoGround technology into a single device, designed to purify USB power and data for high-fidelity audio systems. It ensures cleaner signals and lower noise floors for DACs, streamers, and USB audio setups.

Key Features

• Galvanic isolation: Fully decouples input and output circuits to block stray currents and jitter
• Active Noise Cancellation (ANC3): Cancels electromagnetic and radio frequency interference in the USB power path
• IsoGround technology: Detects and eliminates ground loops, with a grounding port for added control
• External power bypass: USB-C 5 V input lets you power the unit cleanly and disable noisy host power
• High-speed USB 3.0 / 10 Gbps data support: Maintains full bandwidth for high-resolution audio files
• Dual USB-A outputs: One output carries both power and data, the other provides isolated power only

Customer Benefits

By removing noise, interference, and ground loops at the USB source, the iPurifier Pro gives you purer playback, deeper dynamics, and better detail in your audio chain. It’s especially helpful for USB-based DACs and sensitive signal paths, where noise contamination can mask subtle textures.

Use Cases / Ideal For

Best suited for audiophiles, streamers, and high-end USB DAC users who want to suppress noise and preserve signal integrity. Ideal between computer/streamer and DAC, or in any USB-based audio path that demands clean, reliable power.

Compatibility

Works with any USB audio setup—plug between source and DAC or USB device. Compatible with macOS, Windows, Linux, and USB host-capable streamers. The external power bypass is optional but recommended in higher-noise systems.

Pros & Cons

✅ Pros:

• Combines three advanced noise reduction technologies in one compact unit
• Maintains full USB data speed—no throughput compromise
• External power bypass ensures clean supply when needed
• Grounding terminal offers control over ground loop issues
• Low weight and minimal footprint—easy to integrate into setups

⚠️ Cons:

• Requires high-quality external cables for best results
• Full benefit more noticeable in sensitive/high-end systems than basic setups
• No power supply included beyond USB, so external PSU is optional addition

The USB iPurifier Pro is a sophisticated and elegant solution for USB audio noise — ideal for serious listeners seeking cleaner, more refined playback from their digital audio chains.
