You power up your laptop, select your track and press play, then disaster!

You remember how poor the sound quality is. You switch it off and vow never to listen to it again.

The micro iUSB3.0 plugs into your USB port and puts the funk back into your music by:

  • Correcting signal balance
  • Suppressing frame and ground noise
  • Removing USB jitter
  • Reinstating signal integrity

Whether there’s background noise from your power cable, earphones or speakers, the iUSB3.0 cancels it out and restores the warmth and brightness back into your tunes.

Change the way you listen.

The micro iUSB3.0 brings you closer to live music with clear, defined vocals and instruments that feel more rounded and life-like.

Power up your laptop and change the way you listen to music forever.

The tech spec.

The micro iUSB3.0 is powerful to the extreme with:

  • REclock/REgenerate/REbalance Technology – To improve music flow
  • Active Noise Cancellation Military Technology – To cancel all incoming noise

And with two sets of USB ports, you can connect an external hard drive or media server.

It really is the Swiss army knife of audio.

It does everything.

Banish ALL USB gremlins with our Total USB Solution+®. Representing the next gen of computer audio technology the micro USB3.0 works with ¢5000+ DACs.

REclock2/REgenerate2/REbalance2 – cleaner, clearer music.

The 2nd gen of this technology creates an all new signal, eliminates computer jitter and removes noise contamination to restore a ‘balanced’ signal.

Quiet! Active Noise Cancellation+ (ANC) at work!

Exceptionally quiet power. The measured noise floor is 100x quieter than the Common Noise Filter.

Super speed. The USB3.0’s ultra-speed bandwidth of 5.0Gbps offers an incredibly wide bandwidth, ten times that of USB2.0’s 480Mbps.

Vanquish ground contamination. Stay tuned in. Isoground® breaks the ground connection and the ‘Auto/On” USB power line prevents contact with the DAC dropping out.

Dual Ports – just add DAC and HDD. The micro iUSB3.0 operates as a computer audiophile-grade powered hub to serve two devices. One source does not contaminate the other.

Are your devices power hungry? No problem.

This unit is also Bus, Charge 1.2 compliant meaning it can fast charge phones, tablets and even the nano and micro iDSDs!

Good to see that a device that is twice as expensive also performs twice as good

As a follow up on the iFi Nano iUSB3.0 here the review of its bigger brother, the Micro iUSB3.0. It’s twice the price, twice the size but does it also offer twice the quality?
