Cartridge to turntable price ratio

Personally, I think the point of diminishing returns effects the turntable before it does the cartridge.

I agree, just don't put a $5000 cart on a $300 table. 

Better cartridges are always a plus with any well designed modern turntable and price is no indication. I would feel perfectly comfortable putting a Lyra Atlas in a Thorens TD 1600. However, it also depends on the rest of the system and again price is no indication. Most important is a high definition loudspeaker. Some speakers can appreciate the difference a cartridge makes and some can not. 

Depending on your system, Don't forget the tonearm's possible influence.

These “proper” cost ratio questions are…. tedious.

Lewn, then don't read/answer it then. I wasn't asking for thoughts on my question. Before these answers I was thinking of upgrading my turntable before I broke the $2000 price point on a cartridge.  Now probably not. I know the system including the tonearm comes into play. But I wanted to keep the conversation to cartridge and turntable. Thanks to the people whom responded.
