I work in a lab where we have a liq N2 cryo tank. I'll slowly lower the temp of some fuses to -160C and slowly bring them back to RT, and report.
I don't think one week at home freezer will do anything. The theory is that liq N2 low temps will modify the molecular structure and grain of the metal, thus altering conduction through it.
My protocol is 1 day at 4degC, 1 day at -20degC, 3 days at -80degC, 1 week in liq N2, 3 days at -80degC, 1 day at -20degC,1 day at 4degC, then RT and listen.
I will then post listening results and impressions before and after treatment.
Cheers.
