Lots of good info has been provided here. cd318 mentioned that a lot depends on the spec level of your table, that is, what bearing does it have, what sub chassis, what arm board, is the plinth a corner braced version, what bottom plate, what top plate, what power supply, etc. Potential money pit? Yes. Mine is outfitted with the full Stack Audio Ultimate upgrade kit (my kit is the previous version, not the current version). Linn has their own upgrade parts as do other companies.
I would not put a 2K - 3K arm on a basic level table.
The old Linn viewpoint is that the table is the most important then the tonearm is next and the cartridge is last in importance. Of course having all three at a high level is a good thing.
Re: Linn tonearms, something to consider is the head shell size of most of the Linn arms. They are a bit small and can limit cartridge choice except for the Ittok, which has a larger head shell. The Ittok is known for having a "lively or energetic" upper mid range. I have an Audio Origami tone arm. It has a generously sized head shell and it has a more evenly balanced sound compared to the Ittok.
