Yes, i believe this is the same things as Hans B is talking about when he says that it starts looking like this \_/ instead of having vertical lines. This is caused by noise hitting the DAC clock, from how i understand him.
What people has never understood is how incredible sensitive this is. When we do stuff, prior to the DAC, we are basically just modulating the noise and since the DAC is incredible sensitive it reacts even if you only insert another cable, or add an addtional clock, way before in the signal chain since the noise profile changed just a tiny bit.
