That's easy to understand clean boxes = clean sound. My speakers sound much cleaner after dusting too. I have good highs on second floor but better lows in the basement and more "air" when playing outside.

All jokes aside, is it possible that the build up of plaster dust and the like contains some synthetic elements that would have a detrimental effect much in the same way as synthetic elements of say, a carpet and what it does to speaker cables that lie on the floor?
I wouldn't cover my PCs in crap that would be detrimental to the sound so would it stand to reason that all than gunk around the power wires would have some negative effect?
Just food for thought.
All the best,
All jokes aside, what I would wonder is if putting the couple of ounces of plaster back in the box would cause the less clean sound to return.
If (as I suspect) it would not return, it would be an indication that something else was responsible for the perceived change. Perhaps even just having the system unpowered while the cleaning was performed, or just the effects on the contacts of removing and reinserting the power plug.
Which is not to say that anyone would or should bother doing that. But at the same time I would resist the temptation to attribute a perceived change to a seemingly implausible variable in the absence of methodology that is sufficiently thorough to rule out the possibility that something else may have been responsible.
Bojack, I see no basis for having any doubt about Mark's statement. For several reasons:
1)In my book, his many posts here over the years have earned high credibility for the perceptions he reports.
2)Operating temperature, which obviously would be affected for some amount of time afterward by an interruption in power, is fundamental to the physics and the performance of both analog and digital devices and circuits.
3)Overwhelming anecdotal evidence attests to the significance of warmup effects, in some cases over periods of many hours or even days.
4)If digital circuitry or processing is involved, initialization, resets, clearing of memory, the effects of temperature on risetimes, falltimes, and propagation delays, and other such things that occur when power is cycled can affect both those circuits and coupling of noise from those circuits to analog circuits. For example, I presume you've had occasion to see at times how computer behavior can sometimes be affected or corrected by rebooting.
I say all of that, btw, as someone who I doubt would ever be accused of being at or near the extreme "believer" end of the "believer" vs. "skeptic" spectrum.
And, frankly, your concluding phrase was entirely uncalled for regardless of the correctness or incorrectness of what you or Mark had to say.
Getting back to the OPs thread, I did some research on the negative aspects of plaster on power lines and the only thing I could find were a couple of sites. One was a British electricians site where plaster was also asked about and it turns out that modern plaster has no ill effects on wire but older plaster has some corrosive elements in it, especially lime, which eats away at the PVC coating of any wire.
Another site rated plaster as really good at rejecting/blocking RF so I guess it depends on the age and type of plaster so the argument would seem to be whether old, corrosive plaster has a deleterious effect on sound.
I know it is a reach but it's all I could find.
All the best,
