As an engineer working in QA I always think about what can go wrong. While I doubt if I will ever be moving up the Magico speaker line, you never know what might happen in the future. One thing that has always bothered me about the construction of these speakers is human error. We all make mistakes, and I can easily see someone forgetting to apply Loctite, or not enough, to some brace. Then at some point in the future it works loose and some internal rattle starts. What an annoyance that could be. It would start with a 'feeling' that something isn't right, but trying to get to the source of that feeling would be a nightmare.
Anyway, that is just the way I think. Hopefully it is wrong.
