iFi Micro iUSB2.0


The most important feature of any USB audio device (USB DAC, USB Amplifier and USB Speaker etc.) is the power supply. The USB system as well as audio, carries its own power. Perfectly adequate to power anything from USB memory sticks to tablet computers; it falls far short from being a suitable noise-free power supply for high-quality music reproduction. To improve all USB audio devices out there, iFi wanted to develop not just a better power supply, but the best power supply for all audio devices.

With the iUSB, quiet passages are whisper quiet. The climaxes are fiercer and everything in between is richer, more vibrant and no longer grainy. To create a USB power supply that is ultra-quiet is an engineering feat in its own right. They went several steps further. The Super Regulator technology encompasses; multi-stage and multi-order power purifying with filtering. They even commissioned a special, audio-grade USB power supply unit.

The iUSB with an excellent voltage accuracy of 0.5% is even quieter than a 9V dry cell battery. To put it into perspective, if the DC power supply voltage from the iUSBPower was taken as equivalent to the sound level of a large calibre gun fired right next to you (painfully loud, usually taken as around 140dB), the noise produced by the iUSBPower would be completely inaudible to the human ear. The IsoPower system is a completely new way to connect your USB audio device.

There is the standard USB connection option; but with the iFi dual-path Gemini USB cable, iFi engineers developed the IsoPower system which offers the option to run separate power and audio data lines. You wouldn't place interconnects and power cables together so why should the USB connection do it? IsoPower eliminates any pollution between data and power lines. It keeps your USB audio data free from contamination and removes the USB Signal noise from the power supply lines, to enjoy the maximum performance from your USB audio device, unhindered.

iFi engineers developed the advanced IsoEarth technology specifically for the iUSBPower. By breaking the noisy DC ground connection between the computer and your USB audio device, this further reduces the ground noise by a factor of 10. Your USB audio device can now operate in the cleanest environment possible; allowing your music to flow.
