Learsfool, we're not so far apart; there's many things we see similarly. Most different is the amount we would each contribute to the cables in a system and their "importance" overall. Everyone has to decide that for himself.
At first it sounded like you were indicating leaving the cables unplugged for a short period of time, hence my choice of the term "breathing". It seems you're rephrasing the action of unplugging and plugging them in again. If there is indeed an audible effect I would never experience the degradation of sound from leaving cables connected too long, as I break down and rebuild systems on a regular basis.
