Cartridge suggestions for SME Turntable

Zyx Cartridges 

Ok Lalitk, The Koetsu I would recommend strongly against. It really works best in the heaviest of arms and even so it is not a great tracker. You could add weight to your arm but....
The Etsuro is not the greatest tracker at 70um. The Windfeld Ti is rated for 90um. 80 um is IMHO acceptable. 
Both the Charisma and Miyajima Labs are stiffer cartridge's meant for the larger arms the Japanese like. Again you can add weight but...
Your arm is best suited for cartridges in the 13 - 20 um/mN range. Such as The Ortofon Windfeld Ti, any Lyra cartidge, any Clearaudio cartridge, any Van den Hul Cartridge, any Grado cartridge. I generally stay away from cottage companies and stick to the well established generally more technically sophisticated, larger companies. IMHO the Windfeld Ti is the perfect cartridge for you given what you want to spend. The Lyra Kleos would be my second pick followed by the Clearaudio Stradivari V2 and the Van den Hul Frog. 

Dynavector Karat 17DX

I mirror jperry's words...I just bought a Benz Micro LP-S due to advice I got from a few audiophiles.

Here's a review:https://www.avsa.co.za/benz-micro-lp-s-mr-heart-and-soul/
It weighs 16.4 grams.
Good luck!

Effective mass of your SME tonearm maybe ?
