I am still interested to see on what basis you come about this 1-2m taboo length for a digital interconnect as I have not come across it yet. Further more is it based on theory only or have you actually heard faults with this length in used?

It is certainly interesting as I would guess that is what vast amount of people IC in used in real world.... so the implication would be almost everyone has been listening to crap so far. This is a big discovery if you are right.
