You are lucky to have kids that will want and appreciate your audio, when you move on.
My son lives many miles away and has so many other interests, that does not include music, I doubt that anything to do with my audio gear or collection of LPs and CDS would be of much interest to him. My grand son does enjoy a surprising variety of music, but already expressed he has no interest in a lg. audio system, LPs or CDs and grand daughter, only ten, 3,000 miles away with her dad, is a little outdoors girl, interested in horseback riding, camping, hiking and fishing. Is sad that when the wife and I are gone, there will be no one, in the family, interested in our thousands of dollars worth of audio.
In the mean time, I will continue to use and enjoy my system and collection of LPS and CDs, every day. I will continue to upgrade a few things, here and there and never stop checking for a great buy in the media section of The Good Will....Jim
