Theft on this scale is not something law enforcement puts on the top of the list. You would pretty much have to solve the case yourself and then hand if over to the authorities. Sure, they will file a report and create a file, but at this point unless the whole head-fi community and Audeze themselves were to expend all their time and resources to try and break the case (which would require luck and probably some damaging false accusations in the process), it's pretty much over and done.
Not trying to upset anyone, as I'm a new guy to this forum, but as a former business owner who has had stuff stolen and his business broken into, I'm less than optimistic that this will ever get resolved.
I will say though that I bet the people who did do this aren't aware of the head-fi community and I am impressed with amount of heart you all have. I'm glad to have joined the forum.
