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

I'm glad to hear some people tend to experience this problem, I  believe and respect others do not hear it. The issue is I know personally I experience total loss of bloom, bass, spl or energizing of the room or what ever you would like to call it.  All cables are many years old and fully broken in, ranging from JPS, Acoustic Zen, XLO Sig. and Harmonic Technology, so solid core, silver and copper. One thing mentioned is cleaning connections is something I haven't done in a year or so. If some believe removing cables need time to recover sonicly how can you judge adding or subtracting cables to improve things when the benefits or down falls take a few days to hear. My main system I rarely change things. Maybe it's best to set things up best you can and leave it alone and listen to music, it sounds good now

I think if this happens, after turning off gear you've had on for months you should wait 2-3 days first.

Gee, never realized that Toronto was in the Okefenonkee Swamp category of humidity swings ( Toronto being the location where we experienced this sort of phenomenon during a very script heavy shoot...the effect was not subtle and some scenes were re-shot as a result...).

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.
