What would give the best overall improvement

I'm considering updating one piece of my turntable setup. Either the phono preamp, the interconnect to the phono pre, the platter, arm, or the cart - or maybe another piece I haven't even thought of.

I currently have a VPI scout and use the VPI interconnect to my phono pre. I run a Dynavector DV20x2 Low. My phono pre is a Dynavector P75 MKIII set to the enhanced mode.

If I wanted to spend around $1000+/-, would there be a decent upgrade in the price range worth while? I'd like a little more mid bass heft, and maybe a tad more air to the music presentation.
