Hi guys I'm a bit confused does the ifi ipurifier do the same thing as the IUSB.
iUSBPower is a super quiet USB power supply. It replaces the noisy 5V rail from a computer with a very quiet 5V rail.
iPurifier2 rebalances, reclocks and regenerates the USB signal so it cleans both the power and data lines. It is widely reported to be even better if used together with an iUSBPower.
nano iUSB3.0 is iUSBPower and iPurifer2 in one box but better still.
micro iUSB3.0 adds a second audio output so two DACs can be used and also two charging outputs for phones, tablets or whatever.
