Before switching to another speaker, get the 1.6 set up and dialed in as best as you can in your new room BEFORE moving to another speaker.
I have been a Magnepan user my entire audiophile life, starting with the SMGa, MGI, MGIII, MMG, 3.6R. I still use the MMG in a smaller second system.
I did, however, move on from the 3.6R in my listening room to the Kharma Ceramique 2.2 and have no regrets...
