How often do you upgrade turntable ?

1966 various low/mid-fi turntables 

1975 Garrard Zero 100

1977 Empire 598

1999 Pro-ject Pearwood

2000 VPI HW19 MkIII, Audioquest arm

2016 VPI Classic SE, SDS, 3d uni arm

2024 Pure Fidelity Harmony Mk2, Origin Live Illustrious SE arm

I lived with the Rega Planar 2 that I bought in 1981 until the start of Covid. At that point I began a major upgrade to my entire system and over the past years went through the following:

Rega Planar 6

Pure Fidelity Harmony 

Palmer 2.5i

Kuzma Stabi R

CS Port TAT1M2

For me, the CS Port is the end game and it never fails to make me appreciate its ability to deliver an exceptional listening experience.

My mono table is from 1976 - Technics SL-1300MK2 (the cuing arm and lift all fixed).  

My main table is Luxman PD-171 from 2002.  The tone arm was upgraded to Jelco TK850S.  

Unless either of them break, i will probably never replace these tables.
