The Grado Reference ($1200) is a wonderfully musical cartridge, although I can't attest to its compliance compatibility with your Spacearm. I've also heard the Shelter 901 which sounded very good (although, in my system, I prefer my Grado).
Absolute Sound mag also recommends the Sumiko Celebration ($1500) and the Lyra Helicon ($2k). And if you want to save some money and still get a great performing cartridge, you should audition the Shelter 501 Mk2 ($850).
