Arrrrg,
As been reeatedly said . the Regen is NOT about cleaning up USB power.
Its is about stopping the propogation of packet noise from the Dac's USB receiver. It does so by regenerating the USB signal with high signal integrity so as to not cause the PHY in the Dac's receiver from working too hard and hence creating its own noise.
To do so, impedance is well matched and the Power distribution network in the Regen is optimized. All this plus quality reclocking presents a high integrity signal to the Dac.
