No, lampy; a "big fancy test" would be absolutely necessary, including lab measurements to determine what changes were being made in the crossover and blind listening tests to determine if there were any resulting audible differences and if so, were they preferred.

One of the foundations of Axiom, developed at the NRC when Dr. Toole worked with Ian, Alan and other colleagues, was the necessity of blind listening since you simply can't "Just trust your ears" when other factors are present which can affect your judgment. In an intentional bit of hyperbole, Dr. Toole, when speaking to an AES meeting a few years ago stated that "If you can see what you're listening to, then you can't hear it!"
