Best Cartridge for SME309 arm

Also possibly considering Kiseki Purple Heart short body. I am quite interested in that Hana but there is really not that much info on its sound signature....

I’ve tried a number of cartridges on my 12A and ending up settling on a Grado Statement3. I think most MC cartridges are overrated. BTW, Grado holds the patent on the MC cartridge but has always made MM.

I got Hana Umami red and upgraded arm to V and will not look back.... 

I have the Soundsmith Zephyr MIMC Star on my SME309. It is the best tracking cartridge that I have ever had. It sounds great. I have a couple of records going back to the 70s that I thought had bad grooves. The Zephyr tracks them perfectly. I have used Benz and Koetsu cartridges and enjoyed them very much. In the 90s I had a Blue Point Special which was my first cartridge with my SME309 Arm.
The compliance and mass of the Zephyr is nominal for the SME Arm. The Benz cartridges are as well. The Benz and SME are like cream and honey together. But the Soundsmith is my new favorite.

I am using Benz Gullwing SLR on SME 309 with nearly the same specs as the Ruby. Very good match indeed. You can’t go wrong. It replaced a Lyra Kleos which is a good Cartridge but with less body and drive, more analytical. 
Would be interested how the Dynavector sound on a SME 309 even though feom the specs alone the Benz is a better match.
