The only thing that affects my upgraditis is speakers, but then in diy form. I've build almost all my speakers myself and try to do better each time. Amps and electronics tend to be used untill they break down. What is the case is that i now live in a relative big house compared to my old small appartment in the city. So i need a setup in each room at least. That makes me buy more amps and build more speakers.
But my 10 years old Marantz PM5004 is still in use. it's precestor (an old Sony integrated amp from the late 80's) died in action (beyond repair). My good old trusted Goodman Mezzo SL's, once and longtime my main speakers are also stil in use in other spaces. My tube amp is also not the latest series, it's an old series but it does what it needs to do so no need for replacement. And my vintage Luxman preamplifier, that seems to be collectible and go for high prices second hand will soon be sold and replaced by a diy model (build is in progress, design is known and tested) that is not that fashionable, but will sound better i think. It surely will be a lot cheaper. I sold some stuff that i did not like (the Project Debut Carbon DC turntable, some old class D amps and an tascam inteface), but the replacement for my turntable (a second hand but mint Technics SL1500 MKI) and interface (a DacMagic 100) was not more expensive, it was cheaper...
The only thing i think i will buy in the near future are some more integrated amplifiers, as some rooms lack an amp. And maybe replace my dac in my main system with a Topping and put that dac in an other system that does not have one yet (so i use the line out of my laptop, which is crappy). And building more speakers will also happen for diy-fun reasons. But for the rest i got everything i need i think.
But i see in my envirroment that a lot of people's ego's depend on their system, and that they always want the latest, best and most impressive ones. It's sad that they need that to feel a bit secure. But the same happens with cars, clothes, ...
