The iUSB Power is the World's Only Ultra-Quiet USB Power Supply - Quieter Than a Battery: Bypass the Noisy USB Power from Your Computer and Replace it with Fresh, Clean Power
You've never seen or heard anything like the iFi iUSBPower because there's never been anything like it. The world's quietest USB power supply, it removes noisy USB power from your computer and replaces it with clean power, eliminating any pollution corrupting your data. Designed to be the best power supply for all audio devices, no matter the price! iUSBPower boasts a Super Regulator purified power supply, the innovative IsoPower connection system, and IsoEarth technology. Use the iUSBPower with any DAC, and the level of sonic improvement you'll hear will be shocking. Pair it with the iFi DAC or any USB DAC in the world, and you'll be in heaven.
"In my nearfield desktop system replacing the stock AC power supply with the iUSBPower lowered the iDAC's already low noise floor to the point where it sounded very much like what I'm used to hearing from a live microphone feed. Micro-dynamics seemed more pronounced when the iUSBPower was attached and the smallest details buried in the mix were easier to hear."

Super Regulator Technology Combines Purifying With Filtering
At its core, iUSBPower lowers the noise floor, enhances microdynamics, delivers whisper-quiet soft passages, improves sonic richness, and unearths important musical details. Quieter than a battery, it elevates the vibrancy and lifelikeness of any music you play. Its Super Regulator technology encompasses multi-stage and multi-order power purifying with filtering. An audio-grade USB power-supply unit and incredible voltage accuracy help explain why the iUSBPower supplies the cleanest power ever.
"This has some serious implications for the deluxe music server sector. Why spend $2-3k building a bespoke PC or buying off-the-shelf megabuck servers when a $200 appendage will soothe EMI/RFI nerves on ANY device with a single clunk-click? At that price, EVERY serious digital audiophile should have one. A round of applause, please."
– John Darko, Digital Audio Blog
An Entirely New Way to Connect Your USB Audio Device
More than just a stunningly quiet power supply, iUSBPower offers an entirely new way to connect your USB audio device. Sure, there's the standard USB option. But taking into account the iFi dual-path USB cable, iFi's IsoPower system allows you the opportunity to run separate power and audio data lines - much like you already do with separate interconnects and power cables. IsoPower eliminates any pollution between data and power lines, keeping your USB data free of contamination and removing USB signal noise from power-supply lines. You'll hear your USB devices perform at their maximum ability.
"This was another review where it was mostly all fun from the first to the last notes played through the iFi duo."
– Michael Lavorgna, AudioStream
Reduces Ground Noise by a Factor of 10
Specifically developed for the iUSBPower, IsoEarth breaks the noisy DC ground connection between your computer and your USB audio device, further reducing ground noise by a factor of 10! With the iUSBPower, your device will operate in the cleanest-possible environment, affording music to flow through unimpeded and with utmost transparency.
Not an Add-On But an Essential Audio Component
If you're serious about sound, there's no reason not to at least give the iUSBPower a shot in your system. It's 100% Music Direct Money-Back Guaranteed. And it'll have you wondering why it took so long for a manufacturer to come up with its likeness. Thanks, iFi.
