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.
Depends on how many times you have heard Ted Denney tell you that if you move the cables, you have to wait days for them to settle ... as his excuse for never doing double blind tests, even though he has claimed he would, but then backed out.

George Cardas of Cardas Audio has stated many times that simply moving cables will degrade the sound and it will take several days for the sound to recover. 

It is always educational to hear the difference of an audio system at an audio show on day one as compared to the final day.

10db would be more a concert hall / outdoor venue figure, but completely possible

The venue was about 15 mil cu ft....a large warehouse space converted to studio use. It was right beside Lake Ontario (like about 40 ft away). We did the tech survey in February and shot in August. And we had recordings of the before and after, and tape don’t lie ( read ..tape provides a fairly objective view of the event unencumbered by the ear brain editing functions...).

Cardas also says things like this below from their website. Note that any standing voltage is DC (music is AC). However, if I take a fairly inexpensive 2 meter interconnect I have lying around that has not been connected up to anything in months, load it with 100K ohms (higher than most inputs), and hook that up to a 6.5 digit Agilent 34465 meter, I measure <10uV, or at least 100db on a 1V signal, and lower than the offset of any practical amplifier. Of course, the source is likely around 2K, so that 10uV, would be much less.

There are many factors that make cable break-in necessary and many reasons why the results vary. If you measure a new cable with a voltmeter you will see a standing voltage because good dielectrics make poor conductors. They hold a charge much like a rubbed cat’s fur on a dry day. It takes a while for this charge to equalize in the cable. Better cables often take longer to break-in. The best "air dielectric" techniques, such as PFA tube construction, have large non-conductive surfaces to hold charge, much like the cat on a dry day.

Also said this, yet I can put an unused interconnect in front of a speaker playing loud, load one end with 2K (mainly to shunt RF via AC), plug the other end to the AP, and not measure anything above -120db except a spike at 60Hz if the cable is not routed properly?
Cable that has a standing charge is measurably more microphonic and an uneven distribution of the charge causes something akin to structural return loss in a rising impedance system
Cardas makes a lot of other claims, and like the ones above, while there is truth in them, it is the old "lie and statistics" thing. Let’s take that standing voltage thing. I measured <10uV. Cardas says in their marketing blurb, MV (millivolt range, or 100 times more). Who is telling the truth??? We both are. The difference is, I loaded the cable with a rather unrealistic 100K load. I should have loaded it with say 10K to represent a worst case source impedance. That would have brought it down to say 1uV or 1000 times less than Cardas’ marketing number. What did Cardas use? ... likely the input impedance of their meter, perhaps 10 meg (million) ohms. A completely unrealistic number for an interconnect, and a ridiculous number for a speaker cable to power cable.

For a microphone cable with low signal levels and high impedance, micro-phonics is an issue. Teflon being stiffer than say foamed PP/PE (or an air dielectric) is potentially much less susceptible to microphonics as you have less moving of the conductors, which causes pumping of the voltage as with any capacitor if you keep the charge constant. Of course in microphones you often have microphones with a high DC bias which forms a way higher charge on the cable than any "standing charge" ... many orders of magnitude.

You never really get all the way there, you sort of keep halving the distance to zero. Some charge is always retained. It is generally in the MV range in a well settled cable.

To be fair, it is a valid concern for MM cables.
