This gets passed around the complete system by our cables causing further damage and microphonic effects.
Correct, once noise is in there, it will always be there; in the analogue world, this is why gain structure is so important, maximum gain on the first stage so any further noise isn't amplified and ideally attenuated down the line.

Even in the analogue world, these effects should be irrelevant with good engineering, but noise due to vibration on a digital interconnect is so far away from the signal it should be completely rejected. If the cable is broken, has a dry joint etc. this would make difference.

If anyone likes to experiment, make (or buy) a long digital SPDIF cable and insert it into your system looped out to your listening position, whilst listening to music, grab the cable and give it a good shake. Let me know the results.
