“It has been 3 years since my original review of iFi Audio’s original micro iUSB Power, iDAC and iCAN…..iFi Audio has decided to update the original models with newer parts, better tech, still excellent sound quality and always a big bang for the buck.”
iDAC 2: “Let begin with iDAC2. Besides sharing the same name with the original iDAC, there is really nothing really similar between the two. Where the original iDAC is meant to be a step beyond entry level USB DAC, the iDAC2 simply takes it to the next level…..All and all, the iDAC2 is a solid upgrade over the original model. I’ll dare to even say it is almost a quantum leap in design.”
iUSB3.0 Nano: “Compare to the iUSB Power for only cleaning up the USB power line, the new nano iUSB3.0 is also a fully suited up USB3.0 hub that not only clean up power line, but also clean up the USB data signal as well as supporting BC1.2 profile. It is pretty much as audiophile as USB hub can ever be. Of course, whether you will detect an improvement with or without nano iUSB3.0 depends on how good or bad your PC’s USB connection is. If it doesn’t have much problem to begin with, then you might not notice much improvement. If it does have problem, then the nano iUSB3.0 will prove to be a good fix.”
iCan Micro SE: ” The main difference is that the iCAN SE, with a higher voltage supply from the 15V iPower adapter, can pump out 10 times the power (4W vs. 0.4W) over the same 16ohm load when compared to the original iCAN as well as having a higher maximum gain for the most demanding of headphone. So does the iCAN SE sounds the same as the already great iCAN? Well, yes and no. It is easy to tell that iCAN SE inheres the same underlying tonality and transparent presentation from iCAN, but there are a few subtle improvement.”
