Just a question about the discussion. SH, when you refer to "Industrial Equipment" what equipment specifically are you referring to? My first thought here is....maybe one doesn't critically listen to/evaluate "industrial equipment" so maybe subtle changes (break in?) wouldn't really be relavant or examined. Certainly in Audio, when we are all sitting in the quietness of our houses, listening rooms, studio's etc ..subtle changes might be noticed? Certainly not challenging the premise, just trying to understand all the points of view,

I am one of the loony audio geeks that swear I can hear a differnce in electronics as they age...for whatever reason.....and not always for the better. I'm sure it's my ears that deceive me....THOSE HAIRY BASTARDS!

Peace,
