REclock, REgenerate, REbalance all clean up the signal and restore it to a near-ideal signal (so “bits are bits”).
The hub repeater chip is only the starting point for us. So the reclock is only a part of the equation in the iPurifier 3.
The active noise cancellation and power conditioning clean up the power to the USB (if it draws USB power). Additionally, there is a filtering of ground-borne noise (but no IsoGround to deal with low-frequency ground loops).
