Audio System Donation

Hey I just turned 68 so I'm definitely playing on the back nine. I just ordered the Magnapan 0.7 speakers last week. Got my VAC PA 80 80 with ARC LS 15 pre amp thats been in storage for the past 10 years and figured out a way to set it up in my HT room. I had a dual set up with 2 channel and 5.1 but it didn't have much magic music wise. Hopefully getting back into tubes will cure that. Anyway I have accumulated a fair amount of gear over the years and my wife has now idea what we have of frankly dosen't care. It's not super end but probable worth close to $15k ish all in.
So I need to make a list for her so she can decide to sell or maybe donate to a local church. But they would have no idea what most of the equipment is especially the tube gear. I can hear it now " so that little box is a external DAC?? What's a external DAC??? Also I'm going to drag my 40 year old son over, throw he into my listening chair, fire up the tubes, DAC and .7's
and try to get him to peace out and JUST listen to a few songs of his choice.  Hopefully the penny will drop and he'll keep my gear in the family, or at the very least have an understanding on what I have put together over the years.
So keeping things in perspective, when I turned 63 I bought a dedicated Porsche 944 Turbo S track car and started doing HPDE events. Such fun!! My wife is very supportive, but thinks I'm nuts🤪🤑..............never too late!!

This may not work for you.........but my plan is to right now start selling
off all the "extra" amps preamps tuners CD players DACs integrated amps reel-to-reels that I've been collecting/using for the past several decades.  Boil it down to one system, which is still quite a bit of equipment.  At the appropriate time sell that as well and just go with a 
tube headphone amp and headphones using a streamer as source.
Still probably about $5-7K worth of gear, but can be put in the backseat of a car, as opposed to the truck it would take to move my gear now. No one else in my family has the room or the "room" for it. But they sure as hell enjoy listening to it.
Hopefully I'll know when this should take place. All the best to you.

@jrwaudio my new hero!!!!

for the OP think about where you might like proceeds from sale to go vs. heirs, are there music or arts events / organizations you might like to support ?

@tomic601 That's great as I've never been a hero before :  ))
