SoundSmith cartridges how good?


And how do they compare to others. Forget about cost just thoughts on sonics? Obviously if matched with correct tonearm.

Seeking advice.  Would you guys wait for the Hyperion to be built ( could be months if ever) or scrap that idea and go for the same price point Koetsu Rosewood Signature Platinum? 
Someone above asked - I run my Soundsmith Carmen 2 on the MM setting, hope that helps.
