Interesting thread and from the OPs point of view perhaps downgrading is his best option.
However another option not often mentioned is just sticking.
I’m hoping I’m reaching this stage. I have thought about going active and reducing boxes but am wondering whether this desire is a first cousin of the upgrade path I’ve been “addicted” to for a number of years. That the cure is just stopping.
My thinking (although these pronouncements can be apocryphal) is my system sounds very good, yes it could be upgraded to sound better, yes it may be able to be downgraded and give as much enjoyment - or it could be left as it is and enjoyed full stop.
I’d really like to post here in 10 years time I have the same system in 2031 as I had in 2021.
