Items from audiophile's estate, list and photos link provided; helpful advice appreciated!

Thanks again, tomic601! We're doing OK and just going one step at a time. Be good to yourself, my friend!

This is a challenge to go through. Are there any pictures?

maybe you might want some of this stuff if that’s possible. Or you could purchase it

Who did he buy the gear from does he have any invoices can you go back to these people to see if they want to buy it back or whatever.

I find that people don’t mind spending the money but they do mind when the process is very difficult so they don’t want to deal with it.

Maybe go after the low hanging fruit to reap the most value and then throw the rest in a pile and light a match.

It's not good to read that the gear hasn't been tested so nobody's gonna buy it then or at least have much of an interest

in my experience:

you get the most on usaudiomart. It takes time, 3-9 months

you sell fast on ebay, but they keep 15+ percent

it will sell for less and maybe even more random on FB marketplace. 

But that requires that you list them all, one by one. 

also contact All Elite Audio they are fantastic and could point you in the right direction

Looking at the photos, my sense is that you could sell 10, maybe 15% of it for 10 or 15K, so your original estimate is right. 20 if you get lucky. The rest are unfortunately of little interest today. 

Thanks and good luck. In my view, it would be most effective to simply list descriptions in text of the items and prices if you can. The idea of going to a google drive and opening a pdf of a stranger is not something I want to do. But maybe that's just me.
