The conventional wisdom that you state is generally true, but bear in mind that the turntable / tonearm / cartridge combo is a SYSTEM, and that it it interactive. Hence, using a fine cartridge with an inexpensive turntable / tonearm makes little sense, nor does it make sense to use an inexpensive cartridge with a high quality turntable / tonearm.
Generally speaking, however, you are best advised to get the best turntable / tonearm you can, since a stable foundation is vital to achieving the best performance from the cartridge. It is always easier (and cheaper) to upgrade the quality of the cartridge than replacing the table and tonearm.
