Surely any delay in the re-clocker (likely measured in nanoseconds, maybe tens of nanoseconds) would be completely insignificant compared to changes in path length between the speakers and your ears as you move your head...no?  For example, a head movement of 1 mm towards or away from a speaker would change arrival time by about 3 microseconds which I'd guess is much longer than the propagation delay of the clock signal through the iPurifier2 - but of course, it depends how it's designed.

Yep. That makes sense
