JM Lab Mini Utopia driven by Plinius 8200MKII

Has anyone ever driven Mini Utopias with Plinius 8200 integrated amp? I currently have the Minis and the Plinius 8200 and was thinking of upgrading the amp. Any suggestions or would i just be shelling out too much money for too little improvement with the more expensive integrated amps? I would like to stay with integrateds up to 4000 USD.

The rest of my system is the MF Nu Vista 3D, Analysis Plus cables, DH Labs interconnect.
