George, I can certainly understand your concern and your analysis seems like it might hold water. The problem with your analysis is that in reality tubes are cryo'd everyday in cryo labs around the country without experiencing any problems.
What Exactly Does "Burn In" do for Electronics?
I understand the break in of an internal combustion engine and such, but was wondering what exactly "burn in" of electrical equipment benefits musicality, especially with solid state equipment? Tubes (valves) I can see where they work better with age, to a point, but not quite sure why usage would improve cables, for instance. Thanks in advance for your insight.
