“A magic box called Micro iUSB 3.0!” says MacTechNews.

“iFi Audio Micro iUSB 3.0 is a USB hub and filter, the aim to which is to free the computer audio stream and the USB power supply as well as possible from all possible electromagnetic ‘dirt’…The iUSB 3.0 provides dual USB ports, only capable of transmitting power and data….The sound gain with the Micro iUSB and Gemini cable was enormous in my tests….the sounds difference with and without the 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’.”

Thank you MacTechNew for your awesome review.
