How often do you upgrade your turntable?


And how do you know that it is time to do it? I mean table itself, not arm or cartridge, though this might of course follow.

Upgrading my turntable is (or any system upgrades), is not something necessary or desired, since I completed my Garrard 401 build a year or so ago.

It's all about the music now.

If the TT is not meeting your expectation then I guess you upgrade it. If it is, is far more common to just upgrade the cartridge.

I have two tables - one is 5 years old and another 38 years old. Both have seen their fair share of cartridge upgrades and I have never given any thought to replacing them.
I changed from my AR ES-1 after 30 years. During that time I tricked it out with almost every improvement ever made for it, but as the rest of my system gradually improved over that length of time the day came when I felt like it was time to move on to something that could improve on one or two small areas and give me a bit more flexibility. It otherwise is still a pretty darn good sounding table.
I have been upgrading every few years but since I got my VPI Aries 3x3 I will be set for life.
