Full disclosure: I was sent a sample of the iFi iPurifier 3 by way of iFi and my local supplier, the ever excellent Francois at AudioExchange, in exchange for my honest opinion and review. This is the first in a series of reviews and articles on audio noise and related gear.
If you’re sending audio from your computer to DAC using USB, chances are your sound isn’t as clean as it could be.
Now in its third revision, the aptly-named iFi iPurifier 3 is a small device designed to sit between your digital music source (typically a PC or Mac), and your DAC, taking the signal from your source’s USB output, processing it, reconstructing an all-new ‘clean’ signal, and sending the clean signal to your DAC’s USB input.
All of this is done in real-time, needing no power source other than the power supplied by the USB cable.
Sounds simple enough, right? I mean, who wouldn’t want something that cleans a noisy signal and makes your music sound better for little more than $100? Of course, nothing is that simple, so read on to find out if they hype and the money is worth spending.
