I have heard and believe an excellent table/plinth is the building block for a good turntable.
Effectively the cartridge's job is to measure vibrations so the better the table and the tonearm the easier the job is for the cartridge to get the information.
Some people like car analogies - race tires and good seat and harness keep the driver in position enable a great driver to get more out of a car. If the driver's not skilled then the impact of race tires and properly seating position don't really have an impact.
