Does a new cd transport require break-in time?

As a one-time experimental psychologist working in perception and cognition I suspect I am one of few people in this forum to actually do  human experimentation for a living. I have no time for the double-blind crowd because there are just so many things wrong with their claims. At the outset, experiments  proceed by demonstrating that there are differences between conditions not that there are no differences. In statistics this is called rejecting the null hypothesis.   However accepting the null hypothesis is not proof of no difference, rather it is a statement of failure to find a difference and such results are rarely even accepted for publication because they are inherently suspect on the grounds that any fool can botch an experiment. The auditory judgments underlying high fidelity are subtle and complicated and not going to be teased out without major work meaning many experiments.  In any case I have not heard heard of a single item of audio equipment which has been evaluated and then sold on the strength of scientific testing of its sound quality.  This is not because some equipment is not better than others but rather  the difficulty of doing such work. Like it or not, we rely on the golden ears of designers.
