My system has remained essentially unchanged since late 2015 - it is my final system. The only changes since then are as follows:
1- added a McIntosh PS112 subwoofer - free to me from a friend
2- new phono cartridge (old one wore out- I had it around 20 years)
3- added a music streamer-
4- added a Marantz model 20 tuner- that was free as well
