What Cartridge please?


I have a ClearAudio Concept TT w/satisty tone arm, and currently using a Denon DL110 cart, but I want to upgrade. What is the best cart that this TT can fully utilize?? 
I want to stay with MC carts as I like their sound, and preferably a CA unit, but I'm open in that regard.
My phono stage can handle any cart I throw at it, so no limitations there.

Thanks Fellas,
 Cheers

A $9k cart seems ridiculous for a $1.5k table, let's get serious. There has to be a point of diminishing returns some where. 
I was thinking $2k for a cart is enough for this TT. Or is the Concept more capable?
I had a CA champion and satisfy arm, best results I had were with a ZYX Airy3. I also ran CA, denon, and benz on it but ZYX was better.

Read the threads on the AT-ART-9. LP Tunes has it for under $1100.00. or for even less money, under $500.00, you might want to consider the AT OC9 MKIII, also available at LP Tunes. The ART-9 stays right up there with the big boys and outdoes many of them at their own game.
