I had a planar 3 in England and used a Rega super bias cartridge (one of their cheaper ones). It was not a rocking cartridge (like some Audio Technicas I heard) but it had a subtlety and finess that I really liked. Perhaps the super bias would not be up to the standards of your system but Rega make more expensive (and presumably better sounding) cartridges, so if you're looking for detail and subtlety that may be your thing. Boy I miss my turntable.
