The tests were performed with iFi iDSD Micro, Sennheiser HD800, Audeze LCD-X, HiFiMAN HE-560, Shure 535-LTD, Sennheiser IE800, FiiO X5, FiiO E12A.
“Looking at the specs I was really impressed….Indeed, the unit is very versatile. You can use it just as DAC, just as headphone amp, pre-amp and dac/amp combo of course. The unit can also be used as USB converter as it has a spdif output as well. Besides the above, iFi still had some stuff that impressed me even further…..As I expected, the battery ads clarity and detail to the sound and it is not something hard to notice. The unit sounded very good when it was powered from usb as well and it seemed a little warmer / more analogue….My Shure 535 LTD are very sensitive and I have rarely found an amplifier not to present a small hiss in the background. With iFi the noise disappeared completely proving to be a good match with it….One of the strong things about this unit is that it sounds very natural….The Micro packs a good amount of details. I could hear some subtle things in the songs like only a gentle stroke over a guitar string, a car passing by the recording studio and even an artist scratching his face during the song….iFi Micro iDSD was a really nice surprise. I never expected this quality at that price. I didn’t feel like I was listening to a portable unit at all. I felt like listening to a full blown desktop rig. Actually, I think it might beat a lot of more expensive and bigger desktop rigs.”
