Wijnand, what is talking against the fact that the noise reduction (filtering) is now just making your last DAC clock work perfect, since it is no-longer hit with “any” noise (there is always some level of noise)?
Couldn´t it be that simple, that it is actually only about making the last clock, in your DAC, work as exact as possible?
The other clocks are then actually not involved, from a clocking perspective.
