Ok all,
I haven't read every post yet but here it goes, you will have to excuse me my theory is 15 years old and I have no memory left.
As far as the cables go I have no idea.
Silicone transistors on the other hand have an ambient operating tempeture of 70 degrees farenheight. As silicone is heated the electrons in the atoms orbit break there bonds easier arbitrarilly increasing current flow through a silicon device. (Hypothisys these current flucuations can be eratic over any given frequency therefore affecting the signal at the driver. Just how this will affect the sound I am not sure but at higher frequencies where current flucuations are more noticible it seems that the highs will not be as crisp as they otherwise might be.)
Now for the facts, by freezing the electronics specifically the transistors they maintain there ambient operating temperature longer than they would otherwise. How long this affect will last will depend on the room environment the volume at which the music is played and various other factors.
If you would like to try this experiment there is a better way if you have an air conditioner. Take a flexable conduit and tape it to the output of a airconditioning duct. Cool off specifically your amplifier(s) by placing the other end on the amplifier(s) listen with the airconditioning on, be prepaired for an extended listening session to see if you can hear any difference as the amplifier heats up. DON'T I repeat DON'T cool of the electronics first as you will develop condensation. All you are trying to acheive is a lower operating temperature. If your equipment has been engineered to operate at higher temperatures you may hear no affect. But theory says you probably will.
I would try this as my curosity is now peaked but I don't have an air conditioner.
Remember electronics is PFM. (Pure ******* Magic) This hobby engrains that into my very being more and more every day.
Remember to take the system as a whole.
