Do any of you kids , want your system ???

Nope, to big for their apartment and to heavy to move around. They would rather listen to their iphones.

My daughter MALUCA, a singer songwriter performer (she appears here with Robyn in a video that they wrote together https://youtu.be/xOGFdCWC5ls) has recently asked me for my advice on helping her by an audio system set up for vinyl, but what she wants is nowhere near the quality of my setup. 

I've always thought those Mac ads banging on about 'heirloom quality' big ugly boxes with sharp edges, are selling a delusion.
Like your kids are going to have a suitable home for all those massive boxes. 
Sad truth: your beloved system is destined to become landfill

This is a great thread and very real set of questions, for which I have the following responses bases on what I have done.

(1) First, I think it is important to factor in the kids and where they are in life.  Daughter in graduate school now.  Until she settles down, she will not want to schlep my 15 boxes and crates of audio gear around.  I just don't think they will fit into her Subaru Outback.  But I set the stage for her with a McIntosh RS100.

(2) I wrote into my will what will happen with my audio equipment, music collection and artwork.  Specially, no Habitat for Humanity, Goodwill or Craigslist for this stuff.

(3) I discussed it with my audio dealer already - If I'm gone and you are still in business, please work on selling them on consignment.  I trust they will do it, since they really like my system too and I purchased it from them.

(4) I'm a widower, so no wife to weigh in on what happens.

My 8-year-old son has gotten hooked in a big way.  I set him up initially with a vintage Fischer receiver and a vintage Pioneer direct drive turntable that was given to me by the widow of a long-time music lover.  I replaced the tiny table-top speakers with a pair of Wharfdale bookshelf speakers.  One channel on the Fischer died, so I replaced it with a 35-year-old Onkyo receiver I had stashed away over a decade ago.  He was jealous of my OPPO disc player, so I pulled an old Sony DVD player out of a closet and set that up so he could start listening to CDs.  That morphed into buying him a Bluenode 2i so he can stream as well.

He constantly tells me his speakers are way better than my 25-year-old Von Schweikert VR4s, and his turntable is better than my 35+-year-old B&O.

If I died tonight, he would gladly take my OPPO 205, Bryston amp and Don Sachs preamp.  But he would toss the speaker and TT.  I guess that is better than nothing  :-)
