How often do you upgrade turntable ?

1- (2) Pioneer PL a45d in 1977.

2- (2) Technics 1200s 1984

3-Technics GAE 2019

4- EMT 948 2022

I sold off one 1200 & gave one Pioneer to my Son. My basement system has the 1200 & a Thorens 126 mk lll

My main system carries both the GAE & 948. Both systems run tubes for my taste, even my phono pre’s are tube drivin. I see no reason in the future for any upgrade, but cartridges. 

@huang - Not unless you want to! 

Still have a SYSTEMDEK IIX from the mid 1980's that I bought almost 20 years ago. 

Great sounding TT for very little money that has been quite durable, and does scale nicely with a better tone arm and phono cartridge. 

Like an oil change in the car, every 5,000 miles. ;^)

Sorry @inna, don't mean to make light of your question.  But it seems as long as one is satisfied with the performance and nothing breaks or wares out, why replace?

Yes, why replace ? Only to have something even better. Many keep their turntables for years, I suppose their speakers too. The rest usually gets upgraded more frequently.
