The device makes a noticeable improvement in sound quality that is not limited to blocking occasional clicks and pops from USB. The noise background is much lower and instrument separation is improved. The treble glare on several of my amps is also reduced or eliminated. I also have the iUSB 3.0 bit for the price the iPurfier really makes a difference.
One thing to note however, this thing is really power hungry. If I have it plugged into a MacBook Pro it cuts the battery life in half and it won’t run using the Apple camera connection kit without external power.”
