... what is Settling Time in cables and interconnects...

Purist Audio's fluid cables definitely need at least a few hours to settle after you moved them. Couple of other brands that I have and tried - I heard no difference. But that's my hearing and my system. Still - nothing major, unlike Purist.

The cables will settle in faster if you shake a magic chicken’s foot at them. 

And do you happen to sell chicken feet ?

If you start worrying about moving a cable, you have way too much time on your hands and way too little of other things in them.

In fact, if you are reading this, above applies to you, too, regardless of your thoughts about moving a cable.

If you still insist that cable should not be moved because of some detrimental influence on the sound (why cannot it be better, by the way?), start worrying what all the dust that settles on them will do to the cable and the sound. Cockroaches crawling on them may also not have the best electric properties.

Good news is that settling time for dust is much better established and researched phenomenon than for cables.

Obviously when you’re not an audiophile this sort of thing doesn’t matter. Thanks for the reminder, glubson.
