iFi Micro iUSB 3.0 & Gemini USB Cable Reviews
Set Up and Use

Singer and multi-instrumentalist Rhiannon Giddens, of the revivalist band Carolina Chocolate Drops, sounded ever so present on her solo album, Tomorrow Is My Turn (24/96 FLAC). It is an old school, nicely-produced recording and the emotion in her performances really came through. It really was hard to believe that all of this I was experiencing was through a digital front end costing just about $1000 even, when the cost of the Micro iDSD, Micro iUSB 3.0, and the Gemini cable area all added up.

One of my final listening sessions with the iFi digital bundle was Seal’s magnificent album, System, from 2007. Great songs, great recording. The three pieces working together in my opinion, extracted the most from the music and allowed me to lock into the fusion of acoustic guitars and very tasteful electronica, with Seal’s voice riding on top. It could be the noise floor was kept to an absolute minimum. It could be jitter was reduced to vanishingly low levels. I’m not sure but I know that I find both the iUSB 3.0 and the Gemini essential parts of my system now.


iFI makes a lot of claims about the iUSB 3.0 USB solution and Gemini USB cable. My ears tell me all the engineering has paid off. Not only are the sonic improvements palpable, but the build quality and attention to detail, for such relatively inexpensive high-end audio products, are easy to see.

There is currently a lot of competition in the USB audio enhancement market, and iFi is up to the task. However, according to James Haner, of Avatar Acoustics, iFi’s US distributor, “iFi originally created this product category four years ago with the original iUSB Power. The new iUSB3.0 is a complete reimagining and reiteration of the original meant to be the absolute best in the entire category.”

I would also note that the iUSB 3.0 and Gemini should work with the majority of DACs there, regardless of price, and not just their own. Providing the cleanest signal to the USB input lightens the processing load of even megabuck DACs. Of course, as always, if possible, try before you buy. But I suspect very few audiophiles will not satisfied with the improvements.


iFi Gemini USB Cable: $189
iFI Micro iUSB 3.0: $399
