Dynavector Karat 17D3 for a Pro-Ject RPM 5?

Any thoughts on moving from benz micro mc20e low output to the above mentioned dynavector on my RPM 5? I've heard great things about the dyavector, and I'm getting very curious. I know tonearm cartridge matching is essential, but I know very little about this science.

I don't have problems, with the benz, just curious what spending a little more may get me.

System:
McCormack microphono drive
Spectral DMA 50, DMC 15
Thiel 1.6, MIT cabling

Thanks
