Noise. Noise. Noise.

Computers and laptops are inherently noisy. They can emit up to tens of millivolts of noise.

Plus the presence of a ground connection between the computer and the USB audio device can create earth/ground loops. These will impair sound quality and may also cause buzz and hum.


The micro iUSB3.0 stops all of the above and more besides.

It eliminates USB jitter, ground noise, EMI and RFI, restores signal integrity and corrects signal balance, suppresses frame and packet noise and corrects impedance mis-match.

The only thing it doesn’t do is make coffee!

Make sweet music

Simply plug into your USB port. It will work with DACs up to and above $5000.

Vocals become clearer, more defined, instruments feel more rounded and life-like.


And with dual ports, the micro iUSB3.0 operates as a computer audiophile-grade powered hub to serve two devices – just add DAC and HDD.

One source does not contaminate the other.

Back by popular demand

Most products have a finite shelf life but not the micro iUSB3.0.

We were going to withdraw it BUT you guys disagreed! And with comments like this, how could we not keep it around!

…the sounds difference with and without the micro iUSB is striking and goes far beyond what I would have expected. If you do not believe it, try it yourself..If I had to describe the effect with only one word, then that would probably be ‘purity’.”
