Do any of you fear dismantling your setups?

I know I do. In the past when my system has had time to play undisturbed for a period of time and finally hits its stride I do not want to mess with it. (particularly if it's sounding better than ever) I've already had the experience of disconnecting my system and mysteriously not being able to get it to sound the same again evn after it has time to settle in. I frequently read where other audiophiles move their systems to new dedicated rooms (which is a necessity), but I also read about guys who pull an amp out and take it over to a friends to setup in their system or pull a cdp cables etc. It seems audiophiles readily do this with no fear of any permanent affects it could have on the sonics of the system. I have had bad luck with pulling everything from speaker cables to power cords out. In one case, I re-inserted speaker cables I took out and never got the full mids and room shaking bass I had before. Do any of you fear tearing down your systems for whatever reason because of not being able to replicate the sonic performance you had before?
