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


I've been experimenting with different cables between components. Nothing sounds right since trying to improve sound with new mix of cables. There is no bass and boring, highs are okay but life is gone from system. So I flipped everything back the way it was still sound horrible. Ran everything 24/7 for a couple days still no go. Let it run a couple more days dynamics are back and bass is full big and has tone again and enjoyable to listen to. Can someone tell me why this happens. I've also moved just speaker cables around without unhooking them and seen this happen, I don't get it.

As Bob Dylan said when a disgruntled fan pointed out how crappy some of his more recent albums sounded, especially with respect to dynamic range but also generally speaking, “It sounded good when we recorded it.” Therein lies the rub, you can’t get there from here. It’s the playback system, stupid! Hint - it ain’t the converters.
Yes I agree with  @dmac's friend.
But, I am surprised by people who refuse to hear a change in sound (caused by some change in system) just because they don’t know how to explain this change scientifically.
I think probably everything has to have scientifically explanation, but nobody from us has a full knowledge about the wold around us.
Recently ran into a rather interesting article....( which btw pivots on a notion put forth by Robert Ludwig way back at the dawn of The Great Digital Delightenment...)


And in a voila thingee moment that Ludwig article kinda magically reappeared....

Ludwig must be listening to something other than what is available to everyone else. What everyone else has does not sound like the original recording. That’s just the way things are. Of course, he has a lot of money on the line to make such a pronouncement. 🤗
