I find this interesting.
I don't tell my wife what any piece of my equipment cost, not even the cost of the $50 vinyl LPs I have. But I am afraid of one thing:
That If I die today she would not know what to do with my equipment or how much to sell them for. So I came up with a solution:
I have a large folder with all my receipts, sealed. I told her to open the folder when I die, and I told her who to help her with the sale. She thinks I am crazy. But it's the truth. I don't want her to give the stuff away for pennies, or have family fighting over it.
What have you done to prepare for liquidate of your audio stuff when the time comes? Lets be real about this; the time will come. That's why I drive an old car so that I can enjoy my other toys.
