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

>>>>>Yeah, right. Maybe if you live in the Okefenokee Swamp.

No, but if you live in say Arizona, or you don't humidify you house in a cool climate, then yes humidity can dip into the 10-30% range where frequencies can be attenuate in a large room, especially if you have a "lively" room total energy at higher frequencies is more dependent on bounces extending path length.  10db would be more a concert hall / outdoor venue figure, but completely possible.

Humidity effects (Attenuation of high frequencies) on the sound in a room are very minimal. Just like temperature effects. Over very long distances they add up, though. Now, electric static charge is certainly an audiophile issue and related to humidity. I can’t help notice nobody’s answered by question why bowls of very cold water placed out in front of the speakers improve the sound.

Look, this is pretty simple ... you have not yet readjusted to your original set up. That can take time, so don't sweat it.

Over typical listening temperatures, it does not make much differences, but w.r.t. humidity it can. Depending on the reference quoted, at 5 meters attenuation of 1db at 10KHz  at the right humidity level will happen. When you consider directed sound is only part of the total energy, the path lengths will average longer so higher than 1db at 10KHz is possible. That right humidity being ~20-25%.

With the exception of phono cables and interconnects specifically designed to filter, I guarantee you no interconnect is going to make a 1db change at 10Khz, and keep in mind this causes a change in direct/reflected energy.

Who cares? Most systems are too bright anyway.
