Pro-Ject Debut Carbon DC with Ortofon 2M Red Cartridge vs.Pro-Ject - Debut Carbon Esprit S

Hey, 

I finally got back into vinyl and purchased a Pro-Ject Debut Carbon DC TT and am wondering if the Debut Carbon Espirt S is a major upgrade.

If I upgrade the Debut Carbon will it be as good or better than the Espirit?

Apparently one can upgrade the cartridge and platter.  Are there any other upgrades?

I only have a few days to return it so any recommendations would be greatly appreciated
