I have had good luck with the Denon DL-110 on this turntable and arm. It's a relatively inexpensive cartridge but is very musical and lively without sounding bright. Highly recommended (by me).
I must disagree with Mapman and say that, I think that the DL-103 is a very poor match for this tonearm. The 103 is a very low compliance cartridge that was designed for long, heavy tonearms that were in use at radio stations in the early 1960s. I say this from (lots of) experience with this cartridge. The DL-103 can sound wonderful when mounted on an appropriate arm, but the Linn Basik Plus is not one of them (nor is any Linn tonearm). IMO you can do a lot better for and less money.
