I think the life span of your equipment is different than the utilization of your equipment providing you joy.
I like your equipment and technology has moved forward significantly not only in sources (streamers, DACs and such) but also the cost per sound reproduction in components such as speakers.
I know someone who moved from a vintage system with Carver CD player and and McIntosh pre-amp/amp with Martin Logan speakers tied to structured wiring providing music through in room speakers in the kitchen, patio and garage move to a Sonos set up because was easier to use at a price point versus upgrading a the multi-zone audio system in the house.
Define your goals and budget then you may get some ideas on what you can add and if there's a secondary market for what you may not be utilizing.
