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.
