Conclusions
As electronics and audio theory would tell us, a device like iPurifier does nothing useful for the sound you hear. Marketing material talks about what the device does as far as filtering. But nothing is shown as far as the measured impact on the output of an audio device. And rightfully so because there likely isn't any improvement.
Of course, if you bought this device and plugged it, you immediately hear better bass, more air, more microdynamics and resolution. All of that happens not because the device made these changes, but because when you focus on what a device does, you listen differently. When the sound waves coming out of an audio device has not changed, the only thing that must have, is your perception.
Needless to say, you should not waste your money on such tweaks. You can get a great DAC for the same price as this dongle that doesn't care about USB power quality.
At the risk of stating the obvious, I can not recommend the ifi DC iPurifier. If you have to throw away your money, give it to a needed charity.
