Cartridge for Michell Gyro SE and SME 309

I don't know if this will help you, but I have a Michell Gyro Dec turntable that I bought from a local stereo store. It was their demo table that was up and running, so I had the opportunity to hear it before I bought it. The sale included the cartridge, which is a Benz Micro Reference. I like it so much that I still don't feel compelled to change it. 

Grado cartridges certainly aren't MC, so I'm a bit confused.

@dogberry i know it’s not MC but MI, I wanted to try it if it’s a good match to my TT.

@tonykay I am intrigued by Benz but I heard awhile ago that it’s hard to get. I will check it out. Thanks.
