You are right, mechanical should dominate. My point in commenting is that there are real observations out there that should not be discounted. Too many people say that Magico speakers go through that process to discount it, especially when there are known measurements that show that drivers change over time for a finite amount of time when they are new. They also change electrically over time. What else in a speaker changes electrically over time? Has anyone ever measured that? I know that I have had speaker crossovers modified and Clarity Cap MR installed. The sound absolutely changed over time. What causes that? I don't know. What I do know is that it was a real process similar to hearing a speaker with new drivers. To insinuate that Magico are poorly designed is in my mind absolutely not true. They are meticulously engineered. I have heard the S5 on several occasions at shows, some not so good, some good, and a couple very impressive. What was the reason for the differences? It could be any of a number of things, including speaker break in, system matching and room set up. IME, all of those things are real and matter.
