I cook my cables using an old CDP and an old 25watt integrated amp, where I can set the volume, into a 10watt 5.5R resistor using a couple of music CD's that I like for this process :)This is how I burnin my cables, ie ensure my cables have uniform microstructure, which works for me :)
geoffkait, perhaps you can tell us how you do your home freezer method. Especially as it is a permanent method :)
