I am sorry to read about your health crisis...
i never think about what my wife will do with my audio gear (not very valuable in money anyway). I had a big collection of minerals and it makes me laugh when she said that after my death she will use them as rocks of colors for the walking entrance..
Dont bother with audio gear, think about yourself not about what you wife will do with the gear pieces...
Gives them to some friends...
I wish you the best anyway, often doctors are contradicted by life itself...
The body touch ground not consciousness...
My best thoughts and prayer for you and family...
