Geez thanks Jim

No As Martin not so subtly commented, it's always a good discussion that can weedle out the snake oil from the good oil. Personally I'm finding it an interesting discussion. I work in a scientific environment (a Chemistry department) where papers are published and on some matters even the 'experts' cannot agree with each other and publish contradictory studies, each proving their side of the argument, hell one of them has even spent the last 40+ years experimenting, finding evidence to disprove the current popular belief in the cause of global warming!
I'm more siding with Marcus on this one though, to my way of thinking we've taken a living thing, cut it up and machined it which all must impart stresses on it no matter how careful we are to avoid this (splitting a billet instead of sawing for example). We then glue these bits together, all are "strangers" to each other, all with slightly differing rates of expansion and contraction, in the case of bracing this is wanting to do it in a different direction than the top it's glued to wants to. The whole assembly is one big box full of stresses, we then introduce more by stringing it up! It must therefore take some time to reach a state of equilibrium where the top and box have relaxed or at least "gotten used to" their new lot in life. This state of equilibrium is what I believe is what we maybe see or describe as 'opening up'. I can't see that subjecting it to vibrations in the first years of it's life are going to magically make it open up but if like Gsanbrook, you see this method as working to achieve that goal then go for it, do whatever you feel works for you. I can't see it being the elixir of life for my builds though!
What would be interesting to see with that experiment is the same procedure carried out maybe ten years down the track to see if the results were any different than they were on the first test but of course the listening test would be a useless yard stick then.
