@williamjohnston Your've got to the time in your life, where the very well established patterns are now fragile and maintenance of regular interests are quite possible as being not as important to be maintained.
Your openness on this matter is not the usual, and responding to such a openness is not a daily occurrence for myself.
There is the sense that there is a growing need to Finalise Personal Affairs and if one feels the need to include items used to support their Hobby of listening to recorded music as an area to be included in the action of tidying things up, the intensity of how much is put into it is down to the individual.
For what it's worth, in the past few years, I have bought Audio Equipment from two recent widowed individuals only as purchases made to help out.
l purchased with what I deemed to be a full sensitivity towards the Seller, i.e, not making stupid dealer offers and also sharing with the widower experiences in audio which they seemingly related to and were seemingly contented with hearing.
I do believe the meeting had positives, and the widower was glad to have the encounter.
Having a selection of items remaining for the family to deal with as your estate, where they are fully aware of the asking price to be a fair sale, might assist them with processing their loss, when they get to the place, the items left are now able to be let go.
