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

After some time (hours and hours) on the ol' interweb, I've seen the Shelter 501 and Lyra Delos come up several times. Thinking I may have to put them on my short list. But still open to suggestions.
Consider a Denon DL-S1, LOMC.  There are reviews here and on Audio Asylum.  I do not find any need to upgrade and the price was very reasonable.
I second WillieWonka on the Soundsmith upgrade. Don't underestimate it for the sake of change.

Shawnlh, I haven't personally made the comparison, but I have an industry insider friend who rolls lots of top cartridges, and who positions the AT ART7 & ART9 above both the Kleos and the Delos.  I have an ART7 and will probably try an ART9.  Reportedly the ART9 has a fuller and more dynamic presentation than the ART7(and a more phono stage friendly .5mV output.)  I do have both ART7 and DL-S1 and prefer the ART7.

Whatever the merits of the AT ARTs, there are doubtless audiophiles who won't try them due to confirmation bias favoring higher priced brands.
