That approach made me grin: "These speakers were GREAT when I opened the box, but after a month or so they were really awful!"
It is truly a leap of faith. A new watch, a new street, a new beer, a new carpet - all things we don't see see every day, but find better (or worse) as time goes by. Have they, too, "broken in" in our absence?
Or, another way - our brains are complex, and hardly understood, a state of affairs agreed upon by nearly all experts in the field. So we will disregard that theory, and instead embrace one without any evidence, except opinion.
In the meantime, thanks, Axiom, for getting my replacement here so quickly - four days from phone call to delivery, including a Saturday and Sunday. I've been pleased as can be with All Things Axiom at this point.
