Many seem to be talking about their last system .

i SIT HERE S/P day 6 of quadruple bypass, no big explanation.  but can say a divorce early retirement and substantial income reduction, a new system would be a big deal.  I would like my pre divorce one back.  That would be good enough. 
Unlike some I still want the best sound and did just assemble a  very low cost SET system , which I think might benefit in any number of ways but other things obviously limit what I can hope to do.

In the last 5 years, though I've made certain upgrades to my system, I've probably spent more money on records. There comes a point where, to me, the continual quest to extract the last iota of sound from a reproduction system is subordinate to the the desire to use and enjoy that system to listen for its intended purpose. In the process, I've become less dogmatic about the all analog v digital thing, and can actually enjoy what I have rather than worrying about the 'next big (or little) thing."
@brayeagle- wisdom doesn't always come with age, but it sounds like you are in a good place. 

@mechans -- they probably have you lifting heavy boxes and running the 1/4 mile. You feeling better? 

I retired in June 2017 at 63  1/2 years old.  I  dropped 30K into my 2 systems right after I retired.  I am very happy with both systems and feel I won't be changing.  My income is now half of what it used to be so I won't have the disposable income for many more toys.  I bought all McIntosh pieces with the 30K.  The equipment should last the rest of my lifetime. 

Unlike Bill I am becoming more 'dogmatic', even thinking about reel to reel deck, in fact already decided, it is just a matter of timing. I'll get half track Otari, Studer is just too expensive for me. But I like tape, I'll put everything I need on tape and will keep turntable and records as archive. Besides, very often I don't listen to entire record and I am tired of moving the needle. And if I manage to get some master tape dubs that will be great.
