Maybe you guys were sleeping in class the day they talked about capacitor "forming" and dielectric migration.
Just so you don't misunderstand my position, I don't follow the Mystic Audio Snake Oil Voodoo garbage out there but I also am not so closed minded as to dismiss what others purport to hear. Especially without experiencing the same event. That's just plain stubborn. And that's not how science advances. As engineers you should know that. When I find something that challenges my belief system I want to explore it further, not dismiss it out of hand simply because it doesn't fit the template.
Oh, and by the way, I agree that most of the differences one hears as a new component "burns in" is an adjustment period experienced by the listener. I think the listener gradually calibrates his/her expectations of what it should sound like and compensates accordingly. The ear/brain is an amazing thing.
