What Cartridge please?

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?

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.

I listen to a huge variety of music, about only thing I don't listen to is classical. I prefer strings to air (to a point), and tend to shy away from brass instruments other than the sax. I try not to be too analytical when listening as I find it detracts from the joy, but I like to hear "air" around the instruments. 
In all fairness, the DL110 isn't horrible, but the "air" tends to lack, and the stage can become a bit shallow at times. 

What would be your opinions on this........http://www.lpgear.com/product/AT50ANV.html  The cost fits in with the rest of the system.
