What should my heirs do to dispose of my vinyl and CDs?

@alaric62 same here. My son and daughter will be at odds over my gear and collections. 

Thank you for all the well thought-out suggestions. Those of you with family who value owning a nice music system and the music to go along with it are very fortunate!  Hopefully I have quite a few good years left in me, it's just that I have put so much of myself into optimizing my system and collecting quality recordings over the last five decades that while all is well I should search other like minded folks on this forum for ideas on how to proceed. Thank you to all who have responded.  Any further ideas are very welcome.  All the best!

hifiman5, I can understand your intent, but I wonder if they'll even bother to read it, particularly if it's lengthy and detailed. Instead, they'll probably just get rid of everything as a job lot.

I have a friend who took his collection to a shooting range and use all his records and CD’s as skeet! I saw the pictures and couldn’t decide whether to laugh or cry.

A resonant post.  While I think my son will assume ownership of my hardware (while perhaps not being as passionate about it as I've been ;-), my main concern is the appropriate disposition of collector sets I've accumulated.  As a long-time Deadhead, most of what needs deliberate effort are box sets of Dead releases that are worth 3x - 5x what I paid for them (based on what I see on ebay these days).    I'm talking about a strong 5-digit amount of dough.  From this thread, I picked up the valuable advice to catalog the most resellable pieces to facilitate the process of monetizing them for my heirs.  Great advice.  We ain't getting any younger!
