upgrade path from Dynaudio 52SE

This is what I would change :

Rotel RC-1082 pre
Rotel RB-1092 amp

I kind of agree with Riley804, the Rotel gear is not on the same level as the rest. I would be scoping out preamps, in your shoes. But given your listening preferences, floorstanders cold work better. Is your room large enough for full range speakers?

I don't understand the Rotel hatred on this board. It may be mid-fi stuff but I have tried listening comparisons with Parasound, Classe, BAT, Mac and Krell - all 3-5X the cost of my Rotel gear. There was improvement but not to the tune of $8000+. I suppose I have reached a point in my life that I need to be satisfied with what I have. My room is 12' x 20' with an 80% opening on one of the 20' sides.
