Is getting a new pre-amp the right upgrade path?

Hi everyone - over the last few years I have built a moderate system and tweaked it along the way. I love my Magnepan MG12QRs since I have a small listening room. They are driven by a Rotel RB 991 and a Rotel RC 995 pre-amp, both with upgraded power cords (retrofit IEC connection). Sources are a heavily modified Rega RP3 with Zu Audio DL103 and Music Hall Speed Control. Phono preamp is a Bellari VP 130 and MT 502.  I am looking at the Primaluna Prologue Premium as my next possible upgrade in this chain to give it even more air. Is this the best course of action? Or should I opt for changing the speakers to Magnepan 0.7i? Or replace the turntable with a Rega Planar 6? I’d very much welcome any input .

A tube preamp combined with your Rotel amp could add a more organic presentation and a sense of realism.  
However, the Prologue Premium preamp would not be a match with your amp.
The preamp's output impedance of 2800 ohms is too high for the Rotel's impedance of 36 kOhms. The impedance specs of this preamp makes it more suited to a tube amp.

You mentioned more air. If you mean better separation between instruments and more detail, then the power source of your system should be addressed by lowering the noise floor. eg, dedicated  line of power conditioning.
