Where do you want your system to go when you go?

I laughed when I read your heading but it does have merit.  My kids do not enjoy music the way I do and my equipment would not fit into their houses.  When I sold my last house the people demanded my two-channel system as part of the deal.  At first, I was pissed and said no.  After thinking about it I changed my mind.  It helped me close the deal and I got to pick out a whole new system which was fun.  So, in my case, I would assume my kids will sell my house with the equipment in it.

It's bad enough worrying about my material possessions while I'm alive. After that, someone else can worry about it.

Perhaps a worthy local Audio group?

Find a friend or relative who would be willing to sell your system, either at retail or at wholesale to someplace like The Music Room or a local hi-end dealer. Add a codicil to your will, give the friend a commission on the sale, and the balance of cash goes into your estate.  At the end of the day, it's just "stuff," just like your furniture and clothing.  Your family will want to get everything sold or given away as quickly as possible and move on.

It will be sold off and the proceeds will become part of the estate.
