Your choices are limited: dispose of the gear while you are still alive or leave it to your survivor to deal with. In my case, I have an estate plan that will in theory address both the gear and the record collection.
We tend to value stuff beyond what the market is. I've been through this a few times. I've bought record collections and overpaid only because I wanted to do "right" by the surviving spouse. But, the reality is the market. And it isn't especially good for used high end equipment. Same with motorcycles and a lot of sports cars.
Vintage watches- maybe. Art- depends. Furnishings- I've sent stuff to auction, knowing that it would not fetch what it is theoretically worth.
If you need peace of mind, come up with a plan. Talk to your spouse and to an estates and trusts lawyer. The latter is another outlay.
