Table/Cartridge price ratio

Of all the equipment in audio the cartridge hits the point of diminishing returns first. One can buy a well designed cartridge for under a hundred dollars. One can buy a very, very, good cartridge for a few hundred dollars. Beyond that the improvements, if any, get very expensive indeed. Generally the additional money would be better spent elsewhere.

I also agree with Audiofiel. Diminishing returns is a concept, not a specific dollar amount or an instruction table. For example, an inexpensive Rega arm might well benefit from a cartridge that cost more than the arm itself. A little knowledge and help with specifics may be required.
