Poor guy...

gives an honest impression and gets ridiculed. Actually I feel sorry for the other respondents who have taken the time to ridicule this man without even attempting to try it.
The topic of cryogenics and electronics came up a long time ago in my experience (about 5 years ago). I've talked to an aircraft mechanic who told me they routinely cryo aircraft landing axles by simply placing them in a very large cooler packing them in dry ice and pouring LN over the mixture and then sealing the cooler for a week. Curious, I started experimenting with dry ice and LN which can be bought at many air and gas suppliers.
Using simply dry ice can produce some audible change, although there will be many who can not hear such changes. I purchased a used lab freezer (-80) in order to cut down the purchase of dry ice and LN. I was pleasantly surprised that some change was audible even at exposure to the much higher temperatures.
As usual YMMV
