iUSB3.0 Micro: “Since when I have gone to 100% digital I liked the idea of using an USB DAC, storing all loss-less music on an internal/external big capacity HDD and using a PC for controlling my playlist. Unfortunately on some DACs when touching the mouse or when printer was powering one or in general when many USB devices were connected I would hear some pops, cracks and/or distortions, the focusing became blurry and music itself started to fall apart, losing on precision and critical timing……When I connected iUSB3.0 the sound caught a slightly better focus, the base felt cleaner and on top there were more sparkle……Using iDAC2 directly from PC sounds very good, but this iUSB3.0 lifted its performance on another level, as if I listen to a higher performance DAC……iUSB3.0 is impressive from many point of views, besides the fact that it improves the USB DACs performance, and external HDD can be connected to it as well, the benefits doesn’t stop here and possibly other USB devices with benefit more or less from using an iUSB3.0”
iPurifier 2: “In addition to iUSB3.0, iFi developed something similar but much smaller and more affordable, that is called iPurifier2. Basically it does almost the same thing: cleans the USB signal from all unwanted gremlins, it takes access time back to normal, it reduces jitter and regenerates USB signal……At the end I’ve used Hegel HD25 on which differences were felt almost instantly……One thing I enjoyed very much on iPurifier2 is that any problem you might have with USB connection, some buzzing noise, cracklings or if just your USB DAC looses connection very often when connected to your PC/Laptop then iPurifier2 will solve all those problems.”
Verdict: “Both devices are impressive, through their construction, development and through their principle of operation behind both devices……Thus I consider iPurifier2 a real bargain from iFi if you are not interesting investing to a higher performance DAC. iUSB3.0 becomes an ultimate device if draining the last drop of performance from your DAC is your wish.”
Thank you Darku!
