Many seem to be talking about their last system .

pokey77, thank you for your words.

Sort of a tangential thought, but I don't see much mention of the advances in streaming quality and how that might effect folks systems as they retire and their needs and/or budget change. Tidal has "master tape" quality streaming available for some of its music and rumor has it that Spotify will soon have higher-res streaming available.  You can't really downsize your speakers without losing quality, but one's music collection takes up a lot of space, so these new options make a lot of sense for those wishing to downsize and simplify.  

I'm retired and love CDs and vinyl although not exclusively, and if the streamer isn't working for some reason both of those will (except in power failures...until I get my used submarine nuke plant going). Always. Also it's important to have as much of the stuff you like as soon as possible in life as you could Buy the Farm any day from a number of causes. So the best way to be is wealthy with a lot of toys all over the place....just piles of stuff...simplify schmimplify!
