hi Myriad!
The Sumiko is indeed a good cartridge. The Project turntables comes with Ortofons usually unless specifically asked for something else. We have sold a Project Perspective 2 turntables with the Sumiko Bluepoint 2. they are very good but not as warm as the Ortofons. But this probably would'nt be a problem for you since you are already using a Sumiko.
regards,
Abhishek
