Moving cables around killed dynamics for days anyone else experience this?

It was not apparent to me that the original poster moved the cables back to the exact same spot. So it is still guessing what could have happened. I have only described a few technical possibilities that could have happened. Maybe the dynamics were killed by other possible symptoms like dc-offset on the grid. But I still don't believe in voodoo. I believe in an electrical explanation. Maybe Garth Powell or Cailin Gabriel can shine a light on this matter. 

In most  cases the difference is the amp adjusting to the wire .

How does the AI in the amp know how to respond to external variances? Where can I get one of these amps?

" But why does it need to settle in? That is the question. "
  Have you ever opened a box of cereal and it is half full? When it settles you have all the same quantities of things but they take up less space. This relates to wires settling down and compacting atomic structure that was fluffed up during moving. It is an established fact that reduced space between atoms means better conductance and signal purity. I always take new cables and put them in a vibratory rock tumbler for a day and then with as little as possible additional movement place them in my system. The time reduction to achieve settled signal purity is cut way down doing this.

Last time I was in Toronto , which is nicer than any American city, it was on a very large body of water .
erik is 1000% correct . I believe he lives in the only City in USA that could give Toronto a small run . Montreal as well, which has the Toronto water going bye at high speed .
