Cartridge for Michell Gyro SE and SME 309

You will do much better with a Soundsmith Aida. The Aida has a more advanced stylus profile than the Grado and is also an MI cartridge. Dealing with Soundsmith, IMHE, is better than dealing with Grado although Grado is not bad. The Aida will work perfectly with your arm. You do not get the same level of tracking with a moving coil cartridge until you get to the ones with really small low impedance coils under 2 ohms like the SL Lyras, the My Sonic Labs series and the Air Tight cartridges. All are very expensive and sonically the Aida comes VERY close. Untrained listeners would never know the difference. 

Be aware that MI cartridges do not always mate well with a step up transformer, if you are using a step up transformer.

@lewm I have Aesthetix Rhea so I am covered in that area. I am still looking and have yet to decide. Still looking at different cartridges in my price range. 

Just saw Michell engineering CUSIS S MC. I did not know Michell is making cartridges. What do you guys think about this cartridge?

Well bought Hana ML low output and will mount it on Saturday and see if I made the correct decision.
